the elm leaf beetle xanthogaleruca luteola müller (coleoptera: chrysomelidae), is a serious pest of elm (ulmus spp.) throughout iran. in the present study, lethal and sublethal effects of neem, achook® containing 0.03% azadirachtin, were assessed on mortality, growth, larval weight and feeding deterrence as well as enzymatic and non-enzymatic activities of third instar larvae of the elm leaf be...

A field plots experiment was carried to investigate the influence of soil applications of neem-based (Achook and Nimbidin) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living and plant-pathogenic nematode populations and crop productivity. Data regarding the results showed that all the treatments significantly decreased the number of plant-paras...
