New variants of wheat pathogens are emerging in various countries for which there is no known genetic resistance. The current movement of these pathogens suggests that their incursion into the United States is imminent. The objective of this work was

The use of an appropriate adjuvant for pesticide applications is a critical process to improve spray deposit characteristics on waxy leaves and to reduce off-target losses. After deposition and evaporation, residue patterns of 500 ° m sessile drople

The fate of pesticide droplets on leaves is significantly influenced by the fine structures found on leaf surfaces. Evaporation times and the maximum coverage areas of single droplets (246, 343, 575, 762, and 886 μm) on hairy and waxy geranium leaf

Many insect and disease problems occur in specific plant canopy locations and cannot be managed with systemic pesticides. Diseases such as Asian soybean rust (ASR) (Phakopsora pachyrhizi) infect plant material deep inside a canopy that is difficult t

Conventional boom sprayers usually are not effective in delivering droplets to inner parts of dense target canopies, such as soybeans at growth stages from R3 to R5. An experimental mechanical canopy opener was developed with the assistance of mathem

Information is lacking on spray techniques to improve deposit uniformity within nursery canopies and reduce off-target loss on the ground and via spray drift from the treated area. Spray deposits at various elevations within crabapple trees and on th
