Litchi felt disease is caused by damage to litchi. Damaged leaves and spikes during young shoots and young ear stages of litchi, distorted the leaves, swollen and deformed buds, and covered with felt-like material. Litchi was hidden in the felt. If it was sprayed, it would be difficult to kill the litchi. Alas, it does not cure litchi felt disease. If Qingyuan is combined in the winter season, the damaged branches and leaves will be cut off, burned in a concentrated manner, and then sprayed and prevented, the Litchi pods will be completely destroyed, and the occurrence and damage of the second year will be significantly reduced, which will play a multiplier role. Specific prevention methods are as follows:
After the autumn shoots of Litchi grow fully green and mature, clear gardens are used to remove all kinds of weeds and litter and fruit in the orchards, and then the inside branches of the canopy and the delicate branches and dried branches outside the canopy are removed. Oversized branches, overlapping branches, and pests and branches are cut off, and special attention should be paid to cutting off branches and leaves with felt disease, and then focus on deep buried or burned out of the garden. Spray a 0.8 to 1.2 Baume lime aqueous solution, or a 15 to 20 times alkaline solution, or 300 to 400 times the 45% lime sulfur crystal solution, or 500 to 600 times the 29% lime sulfur agent. Aqueous solution, evenly spray all the branches inside and outside the crown. This will significantly reduce the winter litchi on the branches and leaves, so that the second year of young leaves and flower spikes affected by the litchi pestle, will not appear felt disease.
