Pepper anthracnose and pepper purple spot.

Pepper anthracnose: high temperature and high humidity are beneficial to the disease. After the rainy season or rainstorm, the weather suddenly turns fine, the temperature rises sharply, or the soil moisture is easy to accumulate water after watering, and the disease is rapid. In the case of high humidity in the greenhouse or condensation on the greenhouse film, it is easy to get sick.

Anthracnose control agents include prochloraz, difenoconazole, imazalil, benomyl, bromothalonil, picoxystrobin, pyraclostrobin, etc. Personal suggestion: prochloraz difenoconazole potassium dihydrogen phosphate spray. Once every 5 ~ 7 days. Use 2 ~ 3 times.

Pepper purple spot: it is difficult for plant roots to absorb phosphorus, which is caused by factors such as insufficient soil moisture or low temperature phosphorus deficiency. Apply calcium superphosphate or spray potassium dihydrogen phosphate.

Suggestion: Diphenyl ether methyl cyclopropyl ammonium phosphate potassium dihydrogen phosphate spray.
