Abstract
The invention discloses a bactericide composition for preventing and treating watermelon fusarium wilt, belonging to the technical field of the pesticides. The active ingredients of the bactericide composition include 5-60wt% of metconazole and metominostrobin in the weight ratio of (1:50) to (20:1). The invention also discloses application of the bactericide composition in prevention and treatment of watermelon fusarium wilt. The bactericide composition is developed into three forms having excellent effect on prevention and treatment of the watermelon fusarium wilt by combining metconazole and metominostrobin and adding various auxiliaries; the three forms of the bactericide compositions have obvious synergistic effect on the watermelon fusarium wilt and are capable of obviously improving the prevention and treatment effect; besides, the three forms of the bactericide compositions are capable of replacing part of medium and high-toxicity bactericides, reducing the dosage and alleviating the environmental pollution and residual in agricultural products; due to the application of the bactericide composition in prevention and treatment of the watermelon fusarium wilt, the drug resistance of the watermelon fusarium wilt to single bactericides can be retarded, and the bactericide composition has the advantages of long period of preserving effect.
