Research on Field Control Efficacy of 25％Fludioxonil·Metalaxyl·Thiamethoxam Suspension Seed Coating on Scarabaeidae Scarab in Soybean
In order to clarify the field control effect of 25％fludioxonil·metalaxyl·thiamethoxam suspension seed coating agent on Scarabaeidae scarab in soybean and screen the optimal dosage,this article treated soybean seeds with different dosages of 25％fludioxonil·metalaxyl·thiamethoxam suspension seed coating agent to study its field control effect on Scarabaeidae scarab in soybean.The results showed that the suspension seed coating agent of 25％fludioxonil·metalaxyl·thiamethoxam had a good field control effect on Scarabaeidae scarab.The control effects of doses of 4,5,and 6 g/kg on soybean larvae were 78.17％,84.67％and 88.25％,respectively.When the pre sowing seed coating dosage of soybean was 6 g/kg,the best field control effect was achieved,and it was recommended as a suitable dosage.
