The incidence of 2. Pepper Anthracnose Pathogen development: the temperature range of 1233 C in general, temperature is 25-30 DEG C, relative humidity of about 95%, the most suitable for the occurrence of the disease, the relative humidity is less than 70% is not conducive to disease. Therefore, the summer rainfall, rainy days, high relative humidity, Pepper Anthracnose hair ill.
3. Pepper Anthracnose is a weak parasitic infestation: nearly mature pepper fruits, therefore affected by sunburn or higher fruit maturity more susceptible, from time to time, such as the one-time harvest of dry pepper varieties, anthrax epidemic period beginning in the mid to late 7, the peak period of the disease in August until harvest.
4. in recent years, Pepper Anthracnose in our county, part of the land or crop field, the amount of bacteria, is expected this year will be in place emphasis, large part of the land. Hope that the masses in advance to prevent and control.
Prevention and treatment methods: according to years of experience in the prevention and control, pepper anthrax although the epidemic spread quickly, the harm time is long, heavy damage, but can prevent cure, not terrible. So long as we implement the policy of "prevention first, comprehensive prevention and control", we can effectively control the occurrence and damage of pepper anthracnose.
5. Pepper Anthracnose should advance prevention: general from the beginning in early July, benzoyl azoxystrobin fat with 80% mancozeb, or metalaxyl mancozeb and mancozeb cymoxanil, or star partner per liter of effective ingredients 325 grams, Ji'nan Reiter biological pesticide shengmingyuan tebuconazole, suspensionagent, Shandong Lukang biological pesticide bacteria enemy, early spraying prevention 2-3.
6. chemical control: from the early onset time of spraying control, once every 7-10 days, the incidence of rain, timely spraying, prevent disease spread, spraying to the attention of spray evenly spray penetration. Chemical control of Pepper Anthracnose many: such as protective agent mancozeb, chlorothalonil, propineb; therapeutic agent for more, such as: azoxystrobin, nail care, Difenoconazole, prochloraz, tebuconazole, propiconazole, trifloxystrobin and tebuconazole, etc.. In actual production, the mixed preparations are often used in combination and cross use. The purpose is to delay the drug resistance, improve the control effect and reduce the cost of prevention and control.
