Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

Development and evaluation of a targeted orchard sprayer using machine vision technology [PDF]

Journal of Agricultural Machinery, 2016
Introduction In conventional methods of spraying in orchards, the amount of pesticide sprayed, is not targeted. The pesticide consumption data indicates that the application rate of pesticide in greenhouses and orchards is more than required.

External loading of an orchard sprayer with agrochemicals during application

, 2012
External contamination of sprayers during the application of Plant Protection Products (PPP) can lead to a serious threat for operators and the environment. The residue of PPP stays often on the sprayer surfaces until the end of the spray season when the

Collateralization of the Body in the Central Sahara: On Forms and Effects

Economic Anthropology, EarlyView.
ABSTRACT This article tracks a transporter along the route linking Tripoli to the Saharan town of Ghadames in post‐2011 Libya, asking what secures an obligation when the institutions that normally underwrite it (offices, courts, recognized names) have receded. I distinguish the debt, the sum owed, from the security pledged to answer for it: what may be

“Smart” sprayer technology provides environmental and economic benefits in California orchards

California Agriculture, 2008
Spray applications of pesticides to orchards are a common cultural practice; however, they present environmental concerns due to emissions of volatile organic compounds (VOCs), runoff that can allow pesticides to enter waterways, and spray drift onto ...
