Good effect in preventing litchi and longan ulcer in autumn and winter

Lychee and longan cankers mainly damage tree trunks and branches, and the trunks and branches are covered with mites, which cause the tree to decline and affect the flowering results. Lychee and longan ulcer disease occur severely in high temperature and high humidity conditions, causing madness and rapid spread. Due to the high amount of rain and humidity, the control effect is very poor. Many litchi and longan trees are difficult to control after infection with ulcer disease. If it is controlled in autumn and winter, the effect is good because there is less rain and the weather is dry. The specific prevention methods are as follows:

In the autumn and winter seasons, pay attention to check the trunks and branches of litchi and longan, and find that there are blemishes on the trunk and branches. It is necessary to spray 2 to 3 times 800 times 47% of the spring water of the King of the Kings copper WP solution, or 600 times 20%. The aqueous solution of thidium copper, or 1500 times of 33.5% aqueous solution of quinoline copper, or 1500 times of 46.1% aqueous solution of copper hydroxide, or 800 times of aqueous solution of 4% cerulein wettable powder, is sprayed once every 7-10 days. After the winter lychee and longan clearing garden, spray a 0.8~1.2 Baume aqueous solution of sulphur mixture or 1:1:100 times Pomegranate to evenly spray all the branches and trunks inside and outside the canopy. In this way, the pathogens of ulcer disease on litchi and longan trees can be completely killed. After the temperature rises in the spring of the next year, ulcer disease will not occur, and the mites on the trunk and branches will fall off and the branches and leaves will grow normally.
