Pest identification and knowledge of pest control measures are necessary for the commercial applicator to apply and recommend economic pest treatment. This training manual provides you with information on insect pests, weeds and diseases on agricultural crops, along with pesticide application equipment safety considerations and the proper use of pesticide

A vital part of agricultural crop production in Kansas is economic insect control. Control methods must be considered carefully to achieve economic and responsible crop protection. Some insect problems may be avoided by using insect resistant plant varieties, cultural practices and other non-chemical controls. Some insects help humans by pollinating plants and feeding on other insects that are pests. Care should be taken to protect them. Other insect pests can be controlled by use of insecticides. When chemical control is necessary, special care must be taken in selecting the right insecticide and in applying it properly. Economic insect infestations are more likely to occur early in the growing season when weather conditions are more variable. Control with most insecticides will be more effective when applied under conditions where daytime temperatures rise above 60 oF. The importance of sufficient gallonage in spraying dense stands of foliage should not be underestimated. Usually 12 to15 gallons and up to15 to 20gallonsperacre may be required in rank growth. Under such conditions low gallonage aerial application may not give satisfactory results. On regrowth spraying, less gallonage is required and either ground or aerial equipment may perform satisfactorily; but several factors, including the pest, amount of regrowth, weather conditions, etc., must be considered.
