tailieunhanh - Effect of insecticides, fungicides and herbicides on biofertilizer bacteria and their consortium

Combined soil application of Bio NPK and pesticides either simultaneous and sequential can enhanced plant growth parameters effectively and most of the pesticides tested viz. Profenofos 50% EC, Spinosad 45% SC, Dichlorvos 76% EC, Imidacloprid EC, Fipronil 5% SC, Chlorpyrifos 20% EC, Pyraclotrobin 20% WG, Ridomil 68% WP, Quizalofop 5% EC and Finoxaprop 9% EC found safe to beneficial bacteria at the field recommended dose exhibiting no reduction of bacterial population compared with untreated control. However, broad spectrum and combination of fungicide (Mencozeb 63% + Carbendazim 12% WP) as well as multiple application of pesticide had inhibitory effect on tested individual bacterial members as well as Bio-NPK consortium. Thus, the studies indicated that all pesticides especially insecticides and herbicides are less detrimental to beneficial bacteria used as biofertilizers in common crop management practices. | Effect of insecticides, fungicides and herbicides on biofertilizer bacteria and their consortium
