Azadirachtin is the most active substance separated from Azadirachta indica. lt acts destructively on numerous species of insects and mites. The aim of the presented investigations was to determine the effect of azadirachtin on one of the most dangerous pests of cabbage plants, Pieris brassicae, and on its natural enemy, Apanteles glomeratus. The results of the field observations did not show any repellent effect of azadirachtin relating to laying their eggs cabbage butterflies. However, a significant effect of the azadirachtin solution on reduction the number of cabbage butterfly caterpillars (it was more distinctly marked in respect to young larva stages) as well as on limited feeding by caterpillars. No negative influence of azadirachtin on a parasite of Pieris brassicae caterpillars, Apanteles glomeratus was distinctly shown.

The study was conducted in 2007–2009. Winter rape, spring rape, white mustard, Chinese mustard and winter wheat, grown as previous crop for winter wheat were fertilized with supplemental sulfur. The lowest infection rates were noted on the roots of winter wheat grown after white mustard and Chinese mustard, and the highest – after winter wheat. Sulfur fertilization of previous crop had no significant beneficial effect on the health status of winter wheat roots.
