Do all the agrochemicals affect the population of litter cryptostigmata in the grass ecosystem? 

Author: BANASHREE MEDHI

Abstract :

The impact of agrochemicals, including insecticide (Flubendiamide), acaricide (Fenazaquin), fungicide (Tricyclazole), IGR (Buprofezin), and water-soluble fertilizers (50:40:25 kg NPK/ha) on the abundance of Cryptostigmata mites in a grassland habitat covered with a thick mat of grasses (Botanical Garden) was studied. Among the treated plots, it was observed that two foliar applications of tricyclazole resulted in the lowest population counts at 165 DAT, which was comparable to the effects of fertilizer, buprofezin 2FA, fenazaquin 2FA, flubendiamide 2FA, tricyclazole 1FA, and fenazaquin 1FA. However, buprofezin 1FA and flubendiamide 1FA led to higher mite populations. At 10DAT, higher toxicity was observed in the tricyclazole 1FA treated plot, followed by tricyclazole 2FA, flubendiamide 1FA, and fenazaquin 1FA. Meanwhile, at 80 DAT, a higher population decrease was noticed in the fenazaquin 1FA treated plot, followed by the effects of fertilizer, flubendiamide 2FA, tricyclazole 2FA, fenazaquin 2FA, flubendiamide 1FA, buprofezin 1FA, buprofezin 2FA, and tricyclazole 1FA in comparison to the untreated control.
