Effects of six kinds of seed-coatings,Gannong seed coatingⅠ,Gannong seed coatingⅡ,Gannong seed coatingⅢ,abamectin seed coating AV1,abamectin seed coating AV2 and5.7%emamectin benzoate,on controlling cereal cyst nematode(Heterodera avenae)of wheat,were evaluated in this study.Wheat seeds were treated with eight different seed-coatings before sowing and the changes in number of cysts in soil and wheat yield were compared after harvesting.The results showed that the numbers of cysts in soil with different treatments were clearly dropped after seed-coating.When treated by Gannong seed coating Ⅲ(1∶35),Gannong seed coatingⅠ(1∶50)and Gannong seed coatingⅡ(1∶35),the cyst reducing rates were 56%,53%and47%respectively.Compared with control,the wheat yields increased 37.6%,19.4%,17.9% and 17.7%treated by Gannon seed coatingⅢ(1∶35),Gannon seed coatingⅠ(1∶50)、Gannon seed coatingⅡ(1∶35)and Gannon seed coatingⅠ(1∶35)respectively.Gannon seed coating Ⅲ demonstrated the best control efficacy,with the characteristics of environmental safety,lower toxicity,labor and cost saving,which is suitable for wide application in practical disease control.
