Peach brown rot, also known as peach fruit rot, is a disease of peach tree fruit caused by fungi. The main symptom is the appearance of brown lesions on the surface of the fruit, which gradually expand and ooze mucus, causing the fruit to rot. In severe cases, the lesions can spread to the fruit stalk and trunk, affecting the growth and fruit quality of the peach tree.
1) High temperature and high humidity: under the environmental conditions of high temperature and high humidity, the reproduction rate of fungi is accelerated, which can easily lead to the occurrence of diseases.
2) Peach tree varieties: Different varieties of peach trees have different resistance to diseases, and some varieties have thin fruit skin and are susceptible to pathogen infection.
3) Spread of germs: Germs can be transmitted through wind and rain, insects, tools, etc., and once they invade peach trees, they can cause diseases.
4) Improper management: such as excessive pruning, improper fertilization, poor drainage, etc., resulting in weakened growth of peach trees, decreased resistance, and easy disease.
1) Choose disease-resistant varieties: Choose varieties with strong disease resistance to plant, which can reduce the risk of disease.
2) Strengthen orchard management: prune reasonably and keep the orchard ventilated and light-transmittingReasonable fertilization to enhance tree potential;Drain water in time to reduce orchard humidity.
3) Clean the orchard: remove the diseased and residual fruits and fallen fruits in time to reduce the source of germ transmission.
4) Prevention of germ infection: During the ripening period of peach tree fruits, fungicides can be sprayed regularly to prevent pathogen infection.
5) Timely harvesting: Harvest the fruit in time after ripening to avoid overripeness and reduced resistance.
6) Storage and preservation: After harvesting, the peach fruits should be properly stored, and the temperature and humidity should be controlled to prevent the breeding of germs.
Through the above preventive measures, the risk of peach brown rot can be reduced, and the growth and fruit quality of peach trees can be guaranteed.
