Pepper blight often causes the death of pepper plants and the loss of yield, and is a common disease in pepper cultivation. In order to effectively control capsicum blight, we need to understand which drugs are most effective. This article will introduce the specific drug formula of pepper blight to help growers better prevent and control the blight.
1. Symptoms of pepper blight.
Pepper blight is a disease caused by fungi that occurs mainly in the rhizome of peppers. At the beginning of the disease, dark green water-stained lesions appear on the rhizomes, and as the disease progresses, the lesions gradually expand and spread upward. Eventually, the plant will die, the leaves will wilt and fall off, and the fruit will become soft and rotten.
Second, the prevention and control methods of pepper blight.
1.Choose disease-resistant varieties.
The selection of disease-resistant varieties is the most effective way to control pepper blight. Varieties with strong disease resistance can effectively resist the invasion of epidemic diseases and reduce morbidity.
2.Strengthen field management.
Reasonable dense planting, keep the field ventilated and light;Timely removal of sick and disabled bodies to reduce the spread of pathogenic bacteria;Reasonable fertilization to enhance the disease resistance of plants.
3.Pesticide control.
Pesticide control is one of the important measures to control pepper blight. In the early stage of pepper blight, it is necessary to inhibit the pathogen with timely medication to prevent the spread of the bacterium. The use of methyl frost liquid powder, ethyl phosphorus aluminum wettable powder, fluoromorph ethyl aluminum wettable powder, and propylene zinc wettable powder have a good control effect on pepper blight.
These pesticide formulations can effectively control the development of pepper blight and improve the control effect. It should be noted that while pesticides prevent and control pepper blight, the use of fruit Luohan + sodium nitrate naphthalene acetic acid can well repair the diseased parts and promote the absorption of nutrients in peppers.
3. Summary. Pepper blight is a common pepper disease that has a great impact on the yield and quality of peppers. In order to effectively control pepper blight, we need to understand its symptoms and prevention methods. Once the disease is found, spray pesticides in time to prevent and control it. At the same time, it is necessary to strengthen field management, select disease-resistant varieties, and reduce the spread of pathogenic bacteria.
