Abstract
The invention discloses a thiabendazole and prochloraz compounded bactericide. The bactericide contains thiabendazole and prochloraz with the weight ratio of (3:1) to (11:1). The invention also discloses application of the thiabendazole and prochloraz compounded bactericide to prevention and control on wheat scab and rice blast. Compared with a conventional single pesticide, the thiabendazole and prochloraz compounded bactericide has the remarkable synergism on the wheat scab and can remarkably improve the prevention and control effect; the thiabendazole and prochloraz compounded bactericide can substitute part of medium-high poison bactericides, can reduce the use amount, reduce the environment pollution and agricultural product residue, can delay the drug resistance of the wheat scab on a single bactericide, has the long lasting effect, and can reduce the cost compared with a single agent. Practical tests prove that the thiabendazole and prochloraz compounded bactericide has the remarkable prevention and control effect on the wheat scab and the rice blast.
Description
