Weed Management

The recommendations are intended for the commercial vegetable grower who has to make numerous managerial decisions. Although the proper choices of variety, pesticides, equipment, irrigation, fertilizer, and cultural practices are the individual vegetable grower’s responsibility, it is intended that these recommendations will facilitate decision-making. Recommended planting dates will vary across the six-state region. Local weather conditions, grower experience, and variety may facilitate successful harvest on crops planted outside the planting dates listed in this guide. This can be evaluated in consultation with the local agents and state specialists. Government agencies and other organizations administrating crop insurance programs or other support programs should contact local Extension agents and/or vegetable specialists for guidance. EB-236

This bulletin is divided into three sections - disease and nematode control, insect control, and weed control. The recommendations are listed according to crop and then pest. In the table of recommendations given under each crop, the pesticide recommendations are given in units (pints, pounds, and so forth) of commercial products. In most cases, the amount of active ingredient to be applied is given. This information will be useful if the pesticide is commercially available at different concentrations. If a pesticide concentration differs from that recommended, determine the amount of a given formulation you need to use to apply the pesticide at the recommended rate. For example, if the recommended rate is 1 pound of active ingredient, then you should use 2 pounds of a 50 percent, wettable-powder formulation. If the formulation is a liquid, you must know the pounds of active ingredient per gallon to make this calculation.
