Prevention of Peach Leaf Shrinkage

Peach tree leaf disease mainly damages the leaves, and it can also harm young shoots and young fruit. Pathogens grow as ascospores or spores in bark or bud scales, and spores continue to bud when conditions are appropriate. Spores spend winter in scales and bark. Usually in the April-May onset, the damage usually occurs only once. When the fruit becomes sick, it becomes red, the diseased part is swollen, the hairs fall off, and the surface is smooth.

Control methods:

(1) Agricultural control. When building a new peach orchard, choose a variety that is both high-yielding, high-quality, and disease-resistant. For Taoyuan entering the result period, soil, fertilizer, and water management should be well done, and pruning should be carefully performed to improve the ventilation and light transmission conditions. Peach gardens with severe onset should be top-dressed and watered in a timely manner. Spraying fruits and nuts should make the nutrient delivery catheter thicker, increase tree vigor, and increase resistance to disease. During the period of April to May, combined with the operations of pruning during the growing season and controlling the damage of the larvae of the P. erythropoda, it was found that the leaves of the leaf shrivelings were immediately removed and burned in a concentrated manner. Spray the tree maintenance general 1000 times liquid to disinfect and inhibit the spread of germs.

(2) Chemical control. During the dormant season, the general tree is sprayed with 1000 times liquid to eradicate pathogens that have passed through the winter. When the peach bud begins to swell in the spring, it is a critical period for controlling peach leaf deficiencies. Spray 1,000 times the general of tree maintenance, or 70% thiophanate-methyl WP 1000 times, or 50% carbendazim suspension 1 000 Double fluid. In the third to sixth month of the peach growing season, from the time of leaf development to the arrival of high-temperature and dry weather, it is possible to use thiophanate-methyl or carbendazim to add new high-fat lipid membranes, which can be used for heat preservation and enhanced efficacy. The diameter of lesions in the early stage of leaf shrinkage was about 0.2 cm, and the fungicides were sprayed. The lesions were significantly inhibited.
