Field efficacy of 9 pesticides,including azoxystrobin,on peanut brown spot disease and their effects on yield
为提高花生褐斑病的防治效果,保证花生品质和产量,以菏花11号为供试花生品种,设计80%代森锰锌100 g/667 m2(处理1)、70%甲基硫菌灵90 g/667 m2(处理2)、50%多菌灵120 g/667 m2(处理3)、75%百菌清100 g/667 m2(处理4)、97%戊唑醇10 g/667 m2(处理5)、95%苯醚甲环唑12 g/667 m2(处理6)、98.6%嘧菌酯15 g/667 m2(处理7)、95%丙环唑15 g/667 m2(处理8)和97.5%吡唑醚菌酯20 g/667 m2(处理9)共9个药剂处理和1个清水对照(CK),测定各处理对花生褐斑病的病情指数、防效及花生产量的影响.结果表明,处理7和处理9在整个施药期间防效表现较优,其第1、2和3次施药后7 d的防效分别在74.84%～95.24%、74.41%～95.19%,病情指数在1.17～1.89、1.19～1.91;处理7和处理9的花生产量较高,分别为393.77和396.13 kg/300 m2,较CK增产44.64%和45.51%.综合表明,花生生产中,98.6%嘧菌酯15 g/667 m2(处理7)和97.5%吡唑醚菌酯20 g/667 m2(处理9)可作为花生褐斑病防治的高效药剂施用,以进一步提高花生产量.本文为花生褐斑病防治提供参考.
To improve the control effect on peanut brown spot and ensure the quality and yield of peanuts,Hehua No.11 was used as the test peanut variety.A total of 9 pesticide treatments and 1 clear water control(CK)were designed,including 80%mancozeb at 100 g/667 m2(treatment 1),70%thiophanate-methyl at 90 g/667 m2(treatment 2),50%carbendazim at 120 g/667 m2(treatment 3),75%chlorothalonil at 100 g/667 m2(treatment 4),97%tebuconazole at 10 g/667 m2(treatment 5),95%difenoconazole at 12 g/667 m2(treatment 6),98.6%azoxystrobin at 15 g/667 m2(treatment 7),95%propiconazole at 15 g/667 m2(treatment 8),and 97.5%pyraclostrobin at 20 g/667 m2(treatment 9).The effects of each treatment on the disease index,control effect of peanut brown spot and peanut yield were determined.The results showed that treatment 7 and treatment 8 exhibited excellent control effects during the entire pesticide application period.The control effects 7 days after the 1st,2nd and 3rd pesticide applications were 74.84%-95.24%and 74.41%-95.19%,respectively,and the disease indexes were 1.17-1.89 and 1.19-1.91,respectively.Treatment 7 and treatment 9 achieved higher peanut yields,which were 393.77 kg and 396.13 kg/300 m2,respectively,increasing by 44.64%and 45.51%compared with CK.In conclusion,in peanut production,98.6%azoxystrobin at 15 g/667 m2(treatment 7)and 97.5%pyraclostrobin at 20 g/667 m2(treatment 9)can be used as high-efficiency pesticides for the control of peanut brown spot to further improve peanut yield.This study provides a reference for the control of peanut brown spot.
