Effect of Spray Deposit Characteristics on Insecticide Efficacy

Source

Dosage, droplet size, deposit density, and tank-mix concentration are spray deposit characteristics which may influence the efficacy of insecticides. The relative influence of each of these variables on insect control is difficult to measure because of the interrelationships among the variables. Only a few experiments have actually attempted to quantify the relative influence of all of the spray deposit variables on insecticide efficacy. An indirect approach to estimating the relative influence of these variables on efficacy of insecticides for control of Heliothis spp. larvae on cotton was developed and tested over the past 5 years at Mississippi State University. Results suggest that dosage is more important than the other deposit variables in influencing Heliothis spp. control on cotton. Implications of these results and limitations to current research approaches are examined in this paper.
