Pepper rotten fruit control

Rotten fruit is a common problem in the production of peppers. Many vegetable farmers are very troubled and do not know what caused the disease. The author will introduce the common diseases and control methods of chili rotten fruit as follows:

Soft rot

In the early stage of soft rot, the peppers had water-stained dark green patches, and the whole fruit was soft and rotted, with bad odor. The internal flesh rotted and the peel turned white. After drying, the fruits were generally hung on the shoots and fell off when external force was applied.
Control: Use 72% of agricultural streptomycin or 50% DT fungicide or 40% soluble streptomycin sulfate powder and other agents alternate spray, spray once every 7 days, and even spray 2 or 3 times.

Blight

Most of the epidemics were infected from the Department of Gotti and were stained with spots of gray-green stains. They quickly turned brown and rot. In wet weather, a sparse layer of white mold grows on the surface, and the diseased fruit does not shrink. Other parts of the stem, such as stalks, often water spots brown spots.
Prevention: 64% antivirus and 55% Rhizoctonia mixed solution (30g of 15g water is added to both agents), or 58% of metalaxyl manganese 400-600x or 69% of zinc anmanganese 800 ~ 1000 times liquid or 60% zinc manganese fluoride 750 ~ 1000 times and other alternate spray, spray once every 7 days, and even spray 2 to 3 times.

Umbilical rot

Umbilical rot was the victim of the umbilical part of the fruit, and it initially appeared as a dark green water stain and rapidly enlarged. The diseased part shrank and the surface was sunken. It is often blackened or rotted due to parasitic pathogens. Umbilical rot disease is mainly caused by high temperature and drought, insufficient supply of soil moisture, and unbalanced supply of calcium in pepper plants, leading to calcium deficiency in fruits. In addition, partial nitrogen fertilizer can also affect the plant's absorption of calcium, resulting in calcium deficiency in the fruit to produce umbilical rot. When the amount of calcium in the soil is below 0.2%, the disease easily occurs.
Control: Spray with 1% solution of calcium superphosphate or 0.1% solution of calcium chloride. In addition, if the disease department becomes dark or rot, it can be combined with control of black mold or soft rot.
