摘要
为研究花生常用拌种药剂的苗期安全性及田间防效,采用盆栽法测定了3种杀虫剂拌种在不同温度、土壤湿度和播种深度对花生出苗率及生长指标的影响。综合比较得出安全性依次为毒死蜱>氟虫腈>吡虫啉;分别加入4种杀菌剂混配拌种后发现,出苗率和其它生长指标均有所提高,其中萎锈·福美双效果最好。田间试验得出:毒死蜱单独拌种具有较高的杀虫增产效果,加入杀菌剂有一定的增效;吡虫啉与萎锈·福美双混配拌种可提高出苗率及防虫效果,增产率为53.59%;氟虫腈拌种后防虫效果较差,与4种杀菌剂混配后增效不显著。
The objective of this study is to assess the peanut growth in seedling stage and field control on white grub after peanut seed dressing with common agricultural chemicals. To assess the pesticides on peanut growth in seedling stage,the peanut seed were dressed with three different pesticides,and the emergence rate and other growth indexes were recorded after the dressed seeds treated with different temperature,soil moisture and sowing depths by pot experiment. The safety of pesticides to peanut by comprehensive comparison showed as chlorpyrifos fipronil imidacloprid. Mixed use of insecticides and fungicides showed that the added fungicides were beneficial for the emergence rate and other growth indexes,and the carboxin-thiram was the best formula. Field experiment showed seed dressing with chlorpyrifos had good control effect on white grub and final production,and the chlorpyrifos had obvious synergism with fungicides; seed dressing with imidacloprid and carboxin-thiram benefited on germination and white grub control,and the final production increased 53. 59%; The least effective insecticide on grub control was fipronil,and the synergism with 4 fungicides were not significant.
