Using Degree Days To Time Treatments For Insect Pests, Marion Murray Mar 2020

Using Degree Days To Time Treatments For Insect Pests, Marion Murray

All Current Publications

Insecticides that are applied for a perennial insect pest based on a calendar date often result in poor insect control and a waste of resources. Insect activity varies from year to year depending on weather. For example, in Logan, Utah, eggs of the apple pest codling moth began hatching on May 15 in 2005, May 5 in 2006, and April 30 in 2007.

Western Flower Thrips, David Cook, Ian Dadour, Ernie Steiner, Brett Scourse Jan 1996

Western Flower Thrips, David Cook, Ian Dadour, Ernie Steiner, Brett Scourse

Journal of the Department of Agriculture, Western Australia, Series 4

Western flower thrips (Franklinislla occidentalis Pergands) is a serious pest of floral and vegetable crops. From its original habitat in western USA it has now spread throughout North America, Mexico, New Zealand and Europe. David Cook, Ian Dadour, Ernis Steiner and Brett Scourse outline its biology and the control options available.


Tomato Spotted Wilt Virus And Its Management, Lindrea Latham, Roger Jones Jan 1996

Tomato Spotted Wilt Virus And Its Management, Lindrea Latham, Roger Jones

Journal of the Department of Agriculture, Western Australia, Series 4

In 1993, western flower thrips, an important pest of horticultural crops, was found in Western Australia. Since then there has been an upsurge in damsging virus disease epidemics caused by tomato spotter wilt virus in horticultural crops. This has occurred because western flower thrips is a more effective vector of tomato spotted wilt virus than other thrips species. Lindrea Latham and Roger Jones outline the symptoms, spread and management of this serious virus disease in vegetables and ornamentals.


Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble Aug 1990

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.

Thimet For Woolly Aphis Control, G D. Rimes

Journal of the Department of Agriculture, Western Australia, Series 4

THE woolly aphis Eriosoma lanigerum (Hausm) has been known as a serious insect problem in Western Australia since the early days of apple growing.

It was distributed on nursery stock to most parts of the world in the early days of horticulture.


Fruit Fly, D G. Shedley Jan 1960

Fruit Fly, D G. Shedley

Journal of the Department of Agriculture, Western Australia, Series 4

FRUIT fly control is compulsory! To obtain effective control of fruit fly it is necessary to combine strict orchard hygiene with bait spraying.

In addition, cover spraying with DIPTEREX will give extra protection to stone fruit and pears.

When the breeding powers of the fruit fly are considered it is easy to understand why home growers and orchardists need to fight a continual battle against this pest.


Spraying Experiments In Nebraska, J. Ralph Cooper Apr 1917

Spraying Experiments In Nebraska, J. Ralph Cooper

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The more important questions which were considered during the three years covered by the present report were as follows: 1. How many summer sprays are required and when should they be applied? 2. What is the difference in efficiency between various brands of arsenate of lead? 3. What are the relative values of lime sulphur and Bordeaux as fungicides for spraying apples? 4. Is it possible to lessen or prevent Bordeaux injury and at the same time control fungous diseases? 5. Is it possible to interchange Bordeaux and lime sulphur in a spray schedule in such a manner as to …
