In summer, grapes become essential fruits for people's lives and have high nutritional value. Here's how to prevent organic white rot disease.
Grape white rot, commonly known as "water rot" or "ear rot," is often accompanied by anthrax in the more rainy years of South China, Southwest, and North China, causing great losses.
In China, white rot occurs commonly in grapes and is known as one of the four diseases of grapes. The prevalence or widespread occurrence of white rot often leads to losses of 20% to 80%. High humidity combined with warm temperatures (24-27 °C) after hail or rain (long time) can cause the white rot to become popular.
Its prevention and control methods are as follows:
Organic grapes clear the source of the disease. During the growing season, the diseased fruit and diseased leaves were removed in time to cut off the culprit; after the autumn harvest, the diseased skin was completely scraped away, the clean garden work was performed well, and the sickness was brought out of the park and burned.
Strengthen cultivation management. Pick up the heart in a timely manner, trim the secondary tip to make it airy and transparent, and drain the orchard to reduce the humidity. Appropriately increase the distance of the ear from the ground to reduce the chance of pathogen infection.
