Abstract:
The fruit of walnut disease infected with anthracnose was used as experiment material.Pathogens of anthracnose were isolated by dilution plate method.10% shigao,15% triadimefon,12.5% myclobutanil,45% prochloraz,the inhibitory effect of these four kinds of fungicides on pathogenic bacteria of walnut anthracnose at different concentrations and the bacteriostatic effect of compound application were studied,in order to screen out better agents for walnut anthracnose prevention.The results showed that the bacteriostatic effects of 10% shigao 50 mg?L-1,15% triazolidone 150 mg?L-1 and 12.5% myclobutanil 300 mg?L-1 were the best and the control effect of 45% prochloraz with different concentration was very good,the bacteriostatic effect was obvious.The antimicrobial rate of 15% triazolidone,10% shigao and 12.5% myclobutanil complex was lower than that of single use.45% prochloraz 112.5 mg?L-1 was combined with 15% triazolone 150 mg?L-1,10% shigao 50 mg?L-1 and 12.5% myclobutanil 300 mg?L-1 respectively which had obvious synergizing effect on hyphae growth inhibition of walnut anthracnose bacteria.Among them,the combined control effect of 45% prochloraz 112.5 mg?L-1 and 15%triazolidone 150 mg?L-1 could reach 100%,which had relatively excellent control effect and could be recommended for production.
