Improved premixing in-line injection system for variable-rate orchard sprayers with Arduino platform
Unmanned aerial vehicle (UAV) sprayers have been widely used in agriculture. With the goals of using pesticides efficiently and reducing their dosage, we evaluated effects adding not special adjuvants to UAV on droplet deposition control effect leaf folder insects. The quantity coverage area with Kao Adjuvant A-200® rice leaves were better than those without A-200®. Regarding rollers, also bett...
Abstract Dropleg sprayers apply pesticides below the flower horizon of oilseed rape plants and thus reduce unwanted side effects on pollinating insects. Whether this technique benefits parasitoids seed pollen feeding insect pests has not been studied earlier. To answer question, we first assessed vertical distribution using a portable aspirator. In addition, parasitism rates beetle, Brassicoget...
Forest pesticide applicators constitute a unique pesticide use group. Aerial, mechanical-ground, and focal weed control by application of herbicides, in particular chlorophenoxy herbicides, yield diverse exposure scenarios. In the present work, we analyzed aberrations in G-banded chromosomes, reproductive hormone levels, and polymerase chain reaction-based V(D)J rearrangement frequencies in app...
