The Hudson Valley's Experience Securing Endrin For Use In 1977, Warren H. Smith
The Hudson Valley's Experience Securing Endrin For Use In 1977, Warren H. Smith
Eastern Pine and Meadow Vole Symposia
The year 1977 was eventful for Hudson Valley fruit growers who are troubled by pine voles. In March when the snows melted it was clearly evident that serious vole damage to area orchards had taken place and immediate action was necessary to eradicate this menace. Cooperative Extension played a major leadership role organizing grower committee activities, and the North Eastern Fruit Council, a newly formed grower group, represented the industry during these activities. Steve Clark, a Milton, New York fruit grower, was chosen as chairman of the North Eastern Fruit Council grower action committee.
Matters Of Concern In Rodent Control In Pennsylvania Orchards, C. M. Ritter
Matters Of Concern In Rodent Control In Pennsylvania Orchards, C. M. Ritter
Eastern Pine and Meadow Vole Symposia
Rodent control -- both meadow and pine -- has been and continues to be a matter of major concern in all Pennsylvania orchards. Insect and disease problems are vexing but largely seasonal and comparatively easy to correct. Rodent damage, at best, is a debilitating factor in tree growth and fruit production. At worst, it is terminal so far as tree life is concerned.
Preliminary Benefit Analysis Of Endrin Use On Apple Orchards, Mark A. Luttner
Preliminary Benefit Analysis Of Endrin Use On Apple Orchards, Mark A. Luttner
Eastern Pine and Meadow Vole Symposia
This article summarizes the Preliminary Benefit Analysis of Endrin Use on Apple Orchards of September, 1977. The analysis was prepared to be an input to the risk/benefit decision by the Administrator of EPA as to the continued registration of endrin under FIFRA, as amended. A notice of rebuttable presumption against registration (RPAR) of endrin was Issued in the Federal Register on July 27, 1976. If the data on human health and or environmental risks cited in the RPAR are not rebutted and risks outweigh benefits, the Administrator may announce intent to cancel the apple orchard registrations of endrin. This report …

Efficacy Data For Baits Prepared As Candidate Orchard Vole Control Agents, Milo Richmond, Mary Dunlay, Robert Stehn
Eastern Pine and Meadow Vole Symposia
I believe this audience is already well aware of the dilemma in New York State. We have suffered extensive damage from orchard mice over the past three years in New York with some growers losing their entire operation. The pine vole, Pitymys pinetorum, has assumed an Important role as an orchard pest and in eastern New York easily surpasses the related meadow vole, Microtus pennsylvanicus as a significant orchard pest. A recent grower-funded economic survey, initiated by this Unit, and reported in a paper by Pearson and Forsney (1978) points up the severity of losses thru reduced quality and …

Recent Vole Research In New York's Hudson Valley, Jonathan Bart, Milo E. Richmond
Eastern Pine and Meadow Vole Symposia
During fall, 1977, four potential chemical methods for controlling pine voles (Pitymys pinetorum) were evaluated on 12, one hectare plots in three apple orchards in the lower Hudson River valley. Each plot consisted of 45 trees. Three plots were treated with endrin, applied at the recommended rate of 1.5 lbs. per acre; two were treated with 2% technical Vacor (RH 787), applied in an unpelletized meal formulation at a rate of 60-70 gms per tree; two received 10% Vacor in an egg-sugar mix (marketed for human consumption as "Marshmallow Fluff") applied at the rate of 5-10 grams per …

Pine vole attack of one-year-old stem tissue of clones representing many hybrid and other species revealed 5 cultivars apparently less susceptible to damage when compared to Golden Delicious stems. Fusca seemed to be least attacked along with 74R5M9-62, PI 286613, N.Y. 11928, and Hall.
Herbaceous Cover Spray Of Chlorophacinone For Meadow Mice Control In Apple Orchards, Raymond E. Hunter
Herbaceous Cover Spray Of Chlorophacinone For Meadow Mice Control In Apple Orchards, Raymond E. Hunter
Eastern Pine and Meadow Vole Symposia
Very effective control of the short-tailed meadow mice (Microtus spp.) was obtained by means of grass and weed spraying in two orchards with Chlorophacinone. This toxin was applied in one orchard with a boom-type tractor sprayer and in another orchard with a hand-gun nozzle operated from the tractor manually. The anti-coagulant rodenticide in each orchard was mixed in spray tanks at the rate of one pint per 100 gallons water. Spray was directed to an area two feet on each side of apple tree rows applying six pints of the concentrate per treated acre. A five-foot strip of dense …
Reproductive Patterns In The Pine Vole, Margaret Horsfall Schadler
Reproductive Patterns In The Pine Vole, Margaret Horsfall Schadler
Eastern Pine and Meadow Vole Symposia
Reproductive potential in the pine vole is low compared with other small rodents including other species of voles. Age of maturity is late. Males do not reach puberty before 51 days and females before 77 days. Estrus and ovulation are not spontaneous but tend to be induced by mature males. Gestation is long (24 days). Litter sizes are small (2.8 young weaned per female). Litters are produced less frequently because, although females mate and conceive within 3 days of parturition, prolonged gestation insures a minimum of 24-27 days between litters. Only dominant females in a group carry litters to term …
Comparison Of Pine Vole Populations In A Maintained And An Abandoned Orchard, S. K. Kukila, A. R. Tipton, R. L. Kirkpatrick
Comparison Of Pine Vole Populations In A Maintained And An Abandoned Orchard, S. K. Kukila, A. R. Tipton, R. L. Kirkpatrick
Eastern Pine and Meadow Vole Symposia
Before more effective and reliable control methods for pine vole populations can be developed, it is essential to increase our knowledge of the pine vole's basic biology and ecology. Former research conducted by Estep et al (1978) and Noffsinger (1976) has demonstrated distinct differences in food habits, physiological condition and reproductive activity of pine voles in active and abandoned orchards. A summary of their findings is presented in Kirkpatrick and Noffsinger (1977). Results from these studies has promoted an interest to more completely define population characteristics of pine voles in these two orchard types. In this manner, it will be …
An Ecological Framework For Vole Management, Jay Mcaninch
An Ecological Framework For Vole Management, Jay Mcaninch
Eastern Pine and Meadow Vole Symposia
A great deal of past pine vole (Microtus pinetorum) and meadow vole (Microtus pennsylvanicus) research has focused upon toxicants as a means of population control. The advent of more and more environmental restrictions on chemical uses and toxicant resistance in target populations has created endless research in this area of vole control techniques. The application of wildlife management principles through biological and cultural techniques could serve as a sound foundation upon which to build a vole control program.
A Grower's View Of Vole Control Methods, R. N. Barber
A Grower's View Of Vole Control Methods, R. N. Barber
Eastern Pine and Meadow Vole Symposia
Barber Orchards has been an operating orchard since 1903. Our number one problem as far as pests are concerned has been the loss of trees due to mice — pine and meadow vole.
In the 20's, 30’s, and 40's, we consistently lost from 300 to 500 trees per year, even though we were putting out and using every known conventional bait station and bait known to the various states growing apples in a commercial way. We used poisoned oats, wheat, chufers, peanuts and apples which we placed in the runs and holes, as well as under one yard squares of …
A Grower's Experience In Pine Mice Control - 1973 Through 1977, Philip Glaize
A Grower's Experience In Pine Mice Control - 1973 Through 1977, Philip Glaize
Eastern Pine and Meadow Vole Symposia
By 1973 Endrin in Virginia was pro-Ting ineffective. Mice were resistant to Endrin in Most orchards.
Dr. Horafall had started work with Chlorophaclone (C.P.N.) just prior to 1973 and Virginia had cleared it for experimental use.
In November we purchased a considerable amount of the first that was manufactured.
The first C.P.N. that was applied at the recommended rate of .2 lbs. per acre was very effective. The weather was fairly warm and according to our checks we had 90 percent control.
Unfortunately, part of our C.P.N. separated due to a bad formulation and we could not complete the job.
The Meadow, Prairie, And Pine Vole Problem In Ohio, Charles L. Mcgriff
The Meadow, Prairie, And Pine Vole Problem In Ohio, Charles L. Mcgriff
Eastern Pine and Meadow Vole Symposia
Fruit growers, nurserymen, and Christmas tree growers in Ohio suffer economic loss each year if tree-girdling mice are present and not con¬trolled. Unfortunately, in Ohio as elsewhere we have no practical method for arriving at the total value of loss from mouse damage. The grower's reports of losses are merely estimates.
Populations of meadow, prairie, and pine voles are present in Ohio, with pine voles most common in the Southern part. It is essential that the grower identify the species present, because control methods differ, and the same materials are not equally effective for all species.

Pine Vole Control Studies In Virginia - 1977, Ross E. Byers
Eastern Pine and Meadow Vole Symposia
Hand placed baits of Rozol (Chlorophacinone, CPN), Ramik-Brown (Diphacinone, DPN), and Talon (Brodifacoum, BFC) gave excellent control of pine voles in 1977. Vacor (RH 787) did not give adequate control when a meal preparation was hand placed at 10 lbs/A.
Talon and Rozol broadcast at 25 and 22 lbs/A, respectively, gave 100% and 967. control of pine voles. Five lbs/A of hand placed Talon gave equivalent control. A second broadcast experiment of LM 637, Rozol and Talon at 15 lbs/A each was followed by rain the next day but gave 21%, 66%, and 93% control, respectively.

Status Of Pp581 (Volak) Rodenticide Development, Dale E. Kaukeinen
Eastern Pine and Meadow Vole Symposia
In the Proceedings of the first Eastern Pine and Meadow Vole Symposium (March 1977, Winchester VA), ICI was introduced and basic technical information on PP581 presented. PP581 is a second-generation anticoagulant rodenticide, with the approved common chemical name of brodifacoum. The compound is also known as TALON™ in the form of 50 ppm (0.005%) grain-base pelletized bait as developed for control of commensal rodents. The proposed trade name for the orchard formulation of PP581 is VOLAK™. Brodifacoum has been seen to possess several novel characteristics in work with commensal and other rodent species, suggesting a considerable general potential for control …
An Update On Rozol For Orchard Mouse Control, Sol Pitchon
An Update On Rozol For Orchard Mouse Control, Sol Pitchon
Eastern Pine and Meadow Vole Symposia
ROZOL- continues its advance in establishing itself as a reliable product for controlling orchard mice.
ROZOL GROUND SPRAY CONCENTRATE is still the only alternative to Endrin, not only from the persistence point of view, but for its effectiveness. Environmentally, ROZOL GROUND SPRAY CONCENTRATE is proving to be a desirable product because shortly after it controls the mice, it degrades into non-toxic metabolites, thus lacking the residue problems that exist with Endrin.
Furthermore, mouse resistance to Endrin has developed after many years of orchard use. Clear field data has established that ROZOL GROUND SPRAY CONCENTRATE is more effective than Endrin in …
Five Years Of Controlling Meadow And Pine Vole With Ramik Brown, J. G. Connell, W. B. O'Neal
Five Years Of Controlling Meadow And Pine Vole With Ramik Brown, J. G. Connell, W. B. O'Neal
Eastern Pine and Meadow Vole Symposia
Testing of Ramik for control of orchard mice was begun in 1972 in New York. By 1974 there were many test locations all over the Northeast, and by 1975 tests were conducted all over the country. Analyzing the results of some of the early testing suggested some refinements of application technique and formulation. These changes were made to better adapt Ramik to the conditions found in the orchard, and to make it more attractive to the voles. Some of the parameters examined are outlined below:
1. Bait flavor
2. Weather effects on the bait
3. Pellet size
4. Toxicant concentration …
Comments On The Pine Vole In Orchards And Its Control, J. G. Barrat
Comments On The Pine Vole In Orchards And Its Control, J. G. Barrat
Eastern Pine and Meadow Vole Symposia
There are many present orchard problems, most of them seasonal in nature, but few cause the serious losses that extensive vole injury does. Voles do their damage by feeding on the bark of the roots and at the crown of the trunk causing partial or complete girdling which weakens or kills the tree. Vole damage is feared because it means the loss of a tree or a group of trees as a maximum producing unit which takes several years to replace. Partially girdled trees may survive for years with low production. The lack of mouse control is often blamed on …

The Basis Of College Recommendations On Orchard Mouse Control In New York, James W. Caslick
The Basis Of College Recommendations On Orchard Mouse Control In New York, James W. Caslick
Eastern Pine and Meadow Vole Symposia
We all depend heavily upon the advice of others, in making our day-to- day decisions. Months, and perhaps years, before the first ounce of a new rodenticide is used by an orchardist, a series of successful "convincings" must occur. A market analyst must convince his company that a new rodenticide is needed and that a suitable market exists. The company's researchers must convince management that their candidate rodenticide has potential worth exploring. Perhaps researchers outside the company then convince management that outside research services would be beneficial. Researchers must then convince regulatory agencies that the new rodenticide is effective against …
My View Of Our Pine Vole Control Problem, Steve Clark
My View Of Our Pine Vole Control Problem, Steve Clark
Eastern Pine and Meadow Vole Symposia
In a recent survey of pine mouse infestation, it was determined that approximately 37% of the orchard land had serious enough damage to warrant control measures. Some growers are using chlorophacinone as a ground spray. We are also putting out tarpaper bait stations and baiting with either Ramik Brown or Rozol pellets. There has been mixed results with both methods and our growers are still looking for a better control method.
