Abstract

Impact of diamides on structure and functional activities of soil microflora and soil health has not been well studied. Effect of chlorantraniliprole and cyantraniliprole on the activity of dehydrogenase, acidic, alkaline phosphatase, amylase, invertase and urease enzymes in chilli planted soil was assessed. Two applications of chlorantraniliprole @ 30, 37.5 and 60 g a.i. ha⁻¹ and cyantraniliprole @ 60, 75 and 120 g a.i. ha⁻¹resulted in adverse effect. Dehydrogenase activity was reduced by 21.34 and 22.07 per cent on 7^thday, in double dose chlorantraniliprole and cyantraniliprole respectively. Activity of both acidic and alkaline phosphatase enzyme reduced by 4.98 and1.06 per cent at 5th day after application of chlorantraniliprole and cyantraniliprole @30 and 60 g a.i. ha⁻¹ respectively. On the other hand, amylase and invertase activity showed non-significant reduction and urease enzyme activity was slightly reduced (0.02–3.44%). The recommended doses of these two diamides had short term adverse effect on these enzymes, while higher doses led to 20 -30 per cent reduction in enzyme activity). However, activity of enzymes was restored after some time which could be due to adaptive capacity of soil microbes and dissipation of the pesticide residues.

新一代二胺对土壤酶活性的影响

二酰胺对土壤微生物菌群结构和功能活动以及土壤健康的影响尚未得到充分研究。本研究评估了氯氰虫酰胺和氰虫酰胺对辣椒种植土壤中脱氢酶、酸性磷酸酶、碱性磷酸酶、淀粉酶、转化酶和脲酶活性的影响。两次施用氯氰虫酰胺（施用量分别为 30、37.5 和 60 克活性成分/公顷-1）和氰虫酰胺（施用量分别为 60、75 和 120 克活性成分/公顷-1）会产生不利影响。在第 7 天，双剂量氯氰吡虫啉和氰烯吡虫啉的脱氢酶活性分别降低了 21.34% 和 22.07%。在施用氯虫苯甲酰胺和氰烯虫酰胺（30 和 60 克活性成分/公顷-1）后的第 5 天，酸性和碱性磷酸酶的活性分别降低了 4.98% 和 1.06%。另一方面，淀粉酶和转化酶活性没有显著降低，脲酶活性略有降低（0.02-3.44%）。这两种二酰胺的推荐剂量会对这些酶产生短期不利影响，而较高剂量则会导致酶活性降低 20%-30%）。不过，一段时间后酶的活性就会恢复，这可能是由于土壤微生物的适应能力和农药残留的消散。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
