“…Legumes are important in nitrogen fixation in soils and have increasingly become models/markers of toxic effects of chemicals (such as pesticides) in the environment, on plants. Ahemad and Khan [23] reported that fipronil (an insecticide) was stressful to legumes including chickpea, pea, lentil, and green gram, and observed the negative effects of the insecticide on shoot dry biomass, chlorophyll content, root nodule numbers and biomass. Chlorpyriphos had a significantly lower root nodule number/plant than Ridomil.…”

Germination and root nodule formation of soybean (Glycine max) was evaluated in soil treated with Ridomil (R), Chlorpyriphos (CH), and a Combination of both (COM); using a completely randomized design, and a 3×3 factorial arrangement. Factor 1 was the pesticide type with 3 levels-R, CH, and COM; while factor 2 was the contamination rate (v/wt) with 3 levels-0% (control), 2%, and 4%. Aqueous pesticides preparations (as recommended by manufacturers) were applied once, before seeds were planted. More than Ridomil and Combination, significantly (P<0.05) diminished percentage germination due to Chlorpyriphos was observed at 2, 3, and 4 weeks post application. The control had significantly higher germination than 2% and 4% groups, up until the 5th week. The Chlorpyriphos and pesticide Combination groups both had significantly lower root nodule number/plant, than Ridomil. Root nodule number/plant, and nodule biomass/plant were significantly reduced due to pesticide stress at 2% and 4%. Pesticides application at 2% and 4% negatively affected germination and root nodule formation; but there was no indication of an enhanced effect due to pesticides combination.

The present study was designed to screen the Mesorhizobium strains (50) for tolerance in four recommended pesticides for chickpea. It was followed by in-vitro development of robust pesticide tolerant strains by growth in pesticides amended media over several generations. Further, veri cation of the multifunctional traits of pesticide tolerant mesorhizobia under pesticide stress was conducted invitro. Among different pesticides, signi cantly high tolerance in Mesorhizobium strains was observed with recommended doses of pendimethalin (37%) and ready-mix (36%) followed by chlorpyrifos (31%) and carbendazim (30%), on an overall basis. Based on multifunctional traits, Mesorhizobium strains viz. MR2, MR17 and recommended MR33 were the most promising. Ecological performance of the potential Mesorhizobium strains alone and in dual-inoculation with recommended PGP rhizobacterium strain RB-1 (Pseudomonas argenttinensis JX239745.1) was further analyzed in eld following standard pesticide application in PBG-7 and GPF-2 chickpea varieties for two consecutive rabi seasons (2015 and 2016). Dual-inoculant treatments; recommended RB-1+MR33 (4.1%) and RB-1+MR2 (3.8%) signi cantly increased the grain yield over Mesorhizobium alone treatments viz MR33 and MR2, respectively. Grain yield in PBG7 variety was signi cantly affected (7.3%) by the microbial inoculant treatments over GPF2 variety. Therefore, the potential pesticide tolerant strains MR2 and MR33 can be further explored as compatible dual-inoculants with recommended RB-1 for chickpea under environmentally stressed conditions (pesticide application) at multiple locations. Our approach using robust multifunctional pesticide tolerant Mesorhizobium for bio-augmentation of chickpea with might be helpful in the formulation of effective bio-inoculants consortia in establishing successful chickpea-Mesorhizobium symbiosis.
