Mp92-63 Adult Corn Rootworm Management, Lance J. Meinke

University of Nebraska-Lincoln Extension: Historical Materials

The western corn rootworm (WCR), and the northern corn rootworm (NCR) are among the most economically important insect pests of field corn in the Unitd States. Crop losses and control expenses attributed to corn rootworms annually cost producers millions of dollars. Corn rootworm larvae can cause substantial injury to corn plants by feeding on corn roots.

This Extension circular covers these two corn rootworms, their population dynamics, management considerations, and research/emerging technologies.

Ec90-732 Sugarbeet Population And Spacing Calculator

University of Nebraska-Lincoln Extension: Historical Materials

This extension circular is a slide rule used to help a producer calculate the row spacing, seed population, and estimated percentage of emergence of sugarbeet. A producer can also use this slide rule to find the plant population from plants/100 feet of row at 22" and 30" row spacings.

G84-731 Financing Correctional Services In Nebraska (Revised December 1992), A.L. (Roy) Frederick

University of Nebraska-Lincoln Extension: Historical Materials

This is one of a series of NebGuides on financing state and local government. This publication focuses on correctional services.

Correctional services include confinement and correction of adults and juveniles convicted of offenses against the law plus probation and parole activities.

G74-113 A Quick Test For Atrazine Carryover (Revised March 1989), Alex Martin, R.N. Stougaard, Patrick J. Shea

University of Nebraska-Lincoln Extension: Historical Materials

How can you tell if you have atrazine carryover in your fields? Plants grown in soil samples can tell.

Residues of atrazine may remain in the soil and affect some susceptible crops the next year. Crops most often affected include soybeans, field beans, sugarbeets, alfalfa, oats, wheat and many broadleaf horticultural crops.

Attempts to predict the extent of carryover and damage to sensitive crops the year following atrazine use have been only partially successful. The rate of atrazine disappearance and, therefore, the amount remaining the next year, is affected by soil texture, pH and organic matter content, as well as …
