对胡椒瘟的致病菌棕榈疫霉—MF_4用瑞毒霉500微克/毫升、氯唑灵700微克/毫升和乙磷铝2000微克/毫升进行防治试验。参试植株为1龄的班尼约尔胡椒杂交种。在25℃下用胡萝卜琼脂培养病菌。用杀菌剂处理后10天进行接种。接种后30天检查结果。结果表明,瑞毒霉的防效最好,它可完全抑制病斑的扩展,氯唑灵次之,病斑的抑制率为55.7％,乙磷铝效果最差,抑制率为23.9％。 Preventative experiments were carried out on Phytophthora capsici-MF4 of pepper pest with 500 mg / ml of RSB, 700 μg / ml of CBZ and 2000 μg / ml. The test plant is a 1-year-old banniol pepper hybrid. Germs were grown with carrot agar at 25 ° C. Vaccination is carried out 10 days after treatment with the bactericide. 30 days after inoculation test results. The results showed that the best control effect of Renstrus mildew was that it could completely restrain the spread of the lesion. Chlorpromazine was second, the inhibition rate of lesion was 55.7%, and the effect was the lowest, with the inhibition rate of 23.9%.
