The impact of growing season and cultivation systems on the dissipation of profenofos and λ‑ cyhalothrin on Brassica juncea:a comparative study

This study was conducted to contour dissipation patterns of two pesticides (profenofos and λ-cyhalothrin) on B. juncea (green mustard) grown under green house (G.H.) and open field (O.F.) during dry and wet season. The dissipation data of studied pesticides were fitted into the first order kinetic...
