1%噻虫胺·氟氯氰菊酯颗粒剂特种药肥对小麦虫害防治及生长影响试验

Effect of 1%Thiamethasone·Cypermethrin Granule Special Fertilizer on Wheat Pest Control and Growth

噻虫胺是一种新烟碱类杀虫剂,是一类高效安全、高选择性的新型杀虫剂,具有触杀、胃毒和内吸活性;氟氯氰菊酯是一种含氟、低毒并有一定抑螨活性的合成拟除虫菊酯杀虫剂,具有触杀和胃毒作用,无内吸及熏蒸作用,杀虫谱广,击倒迅速,持效期长。为了探索1%噻虫胺·氟氯氰菊酯颗粒剂特种药肥对小麦虫害及生长影响,将1%噻虫胺·氟氯氰菊酯颗粒剂设置成不同处理进行小麦大田试验,研究其对小麦害虫的防治效果,并观察对小麦生长的影响。研究结果表明,1%噻虫胺·氟氯氰菊酯颗粒剂对小麦地下害虫防治率88.30%±0.98%,对蚜虫防治率80.51%,而且对小麦具有明显的增产作用,最高增产率9.59%。

Thiamethasone is one of the neonicotinoid insecticides.It is a new type of insecticide with high efficiency,safety and selectivity.It has contact,stomach toxicity and internal absorption activities.Cypermethrin is a synthetic pyrethrin insecticide with fluoride,low toxicity and certain acaricidal activity.It has contact and stomach toxic effects,no internal absorption and fumigation,wide range of insecticides,rapid knockdown,and long duration.In order to explore the effect of 1%thiabendazole·cypermethrin granule special fertilizer on wheat insect pests and growth,1%thiabendazole·cypermethrin granule was set up as different treatments to conduct field trials of wheat,to study its control effect on wheat pests,and to observe the impact on wheat growth.The results showed that the control rate of 1%thiabendazole·cypermethrin granule against wheat underground pests was 88.30%±0.98%,and the control rate against aphids was 80.51%.Moreover,it had a significant yield increase effect on wheat,with the highest yield increase rate of 9.59%.
