As a spicy Hunanese, I am very familiar with peppers, and I have planted some peppers in my home. Although the pepper is good, there is still a small problem in the planting problem, that is, gray mold. This disease is often seen in the process of planting peppers, mainly harming the leaves, flowers and fruits of peppers, and the rate of infection expansion is also very fast, so it will cause economic losses to the farmers. In the face of gray mold, vegetable farmers have their own small measures to prevent and control, and now Xiaobian talk about these small measures.
First, the harmful symptoms of pepper gray mold
If it is gray mold in the seedling stage, it will damage the leaves and rhizomes of the pepper seedlings. The leaves will begin to turn yellow slowly until the disease is broken. In mature pepper plants, the leaves will show yellow-brown lesions, and the stems will not produce water-stained lesions. During the flowering period, the petals will be wilted, which will affect the growth of the fruit. Once the disease is expanded, all the peppers will appear brown. Spot, which not only reduces the yield of peppers, but also affects the sales of peppers and reduces their own economic returns.
Second, the prevention and treatment of pepper gray mold
1. Strengthen greenhouse and greenhouse ventilation
Cool down the indoor temperature of the greenhouse, you can choose to cool down, or you can water and cool. It is best to water the time in the morning when the weather is fine, and the amount of watering should not be too much. In the rainy weather, it is necessary to drain in time and reasonably carry out ventilation and cooling.
2, remove the bacterial source
It is necessary to remove the sick peppers in time, and the diseased fruits should be buried deep in the distance from the greenhouse. When harvesting peppers, thoroughly remove the diseased pepper plants, enter the field and plow the soil, and clean and bury the diseased leaves remaining on the surface of the land, or cover the mulch to reduce the occurrence of gray mold. .
No matter what crops are planted, there are more or less threats of pests and diseases. At this time, planters need to pay more attention and take some control measures. Of course, if you are interested in other crops, you can also pay attention to Hui Nong. Master more planting knowledge.
