In summer, hot and rainy climate conditions can easily induce the occurrence of various diseases of pepper. In the event of sudden rain after a heavy rain, the climatic conditions in which the temperature is soaring can easily cause disease epidemics, and plant death can be caused within 3 to 5 days, ie, "dead plants." The disease is a devastating disease of pepper. Therefore, it is very important to actively prevent the occurrence of the disease.

I. Strengthening field management

After the seedlings enter the foliage and fruit vigorous growth period, promote pods, attack fruit, return to pods, and prevent decay four times. During the high-temperature rainy season, the temperature is higher than 32°C, and in particular, attention should be paid to the removal of stagnant water after a heavy rain to prevent death. After the hot rain, we must use well water to “pour a garden” to reduce the soil temperature. High temperatures in summer can also lead to the occurrence and spread of viral diseases, causing fallen leaves, falling flowers, and falling fruit. Therefore, during the high temperature season, no rain should be used to pour water once every 5 to 6 days to keep the soil moist but prevent excessive humidity. Appropriate spraying more than 6000 times the love liquid or plant quinolone 7000 times, in order to improve plant resistance to disease.

Second, chemical control

After discovering the central strain in the field, we must seize the opportunity to spray and water simultaneously. Can choose 72.2% Precive 600 ~ 800 times liquid, 72% DuPont Kelu or cream urea manganese zinc wettable powder 600 ~ 800 times liquid. In addition, in the high-temperature rainy season in summer before the watering, sprinkle 96 kg of copper sulfate 3 kg per acre, and then water the control effect.
