As can be seen from the experimental results in the table 2, the seed-metering rate of the ipconazole, fluazinam and clothianidin suspension seed coating agent obtained in the examples 1-5 is significantly smaller than that of a blank control, the control effect on the grubs in the peanut seedling stage is 80.34% -96.16%, which is significantly higher than that of the control agent 8% of the clothianidin suspension seed coating agent in 64.36% of the grubs in the peanut seedling stage, the control effect of the 25% of the ipconazole suspension seed coating agent in 14.29% of the grubs in the peanut, and the control effect of the 500g/L of the fluazinam suspension seed coating agent in 9.91% of the grubs in the peanut. The coating treatment of 30% of the penconazole, fluazinam and clothianidin suspension seed coating agent has the lowest rate of 0.5% on the grubs in the peanut seedling stage, and the prevention effect is as high as 96.16%.
TABLE 3 control of root rot of peanut seeds treated with different seed coating agents
As can be seen from the experimental results in the table 3, the peanut root rot seedling rates of the seed penconazole, fluazinam and clothianidin suspension seed coating obtained in the flower-forming plant period examples 1-5 are all obviously smaller than that of a blank control, the control effect on peanut root rot is 71.42% -91.92%, the control effect on root rot is 59.62% obviously higher than that of the control agent 25% seed penconazole suspension seed coating, and the control effect on root rot is 63.42% of that of the 500g/L fluazinam suspension seed coating. The root rot seedling rate of the peanuts coated with 30% of penconazole, fluazinam and clothianidin suspension seed coating agent is lowest and is 1.02%, and the control efficiency is as high as 91.92%.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
