The mulberry white mulberry is also known as mulberry pod and tree frog. The worm adopts female adults and nymphs to fix sap on the shoots and trunks. In serious cases, the vines hang like a layer of cotton wool. After the branches and trunks are damaged, the tree vigor is weakened. In severe cases, the branches are dry and dead. Once it occurs, if the farmer does not use effective measures to prevent and control, it will cause the entire park to be destroyed within 3 to 5 years. To this end, the author gives scientific guidance to the majority of fruit farmers:
1. Strengthen quarantine on kiwifruit seedlings and scion used for grafting to prevent pest damage.
2, do a good job in the winter garden, and combine pruning, cut off the victim branches, scrape off the overwintering female adults on the branches, and spray a 3 Baume degree lime sulfur agent, eliminate the overwintering insect source, reduce the damage of the following year.
3, in the dormant period of fruit trees, brush with a stiff bristles or thin wire brush, brush off the body on the branches.
4. In the spring before the budding of the tree, spray 5 Baume degree lime sulfur or 40% thawing emulsifiable concentrate 1000 times liquid + soft water pass 4000 times or diesel emulsion. Melting emulsifiable concentrate 5 Baume degree lime sulfur can only be used before germination.
5. Protect and use natural enemies. The natural enemies of Sang Baizhang include red dot ladybugs, black-edge red ladybirds, two-spot ladybugs, and kidney-spotted ladybugs. The protection of these natural enemies will help alleviate the damage of Sang Baixi.
6. Control spraying during the incubation period of mulberry nymphs. When mulberry whiteworm nymphs are found in the kiwifruit garden, 40% of Anmulan EC is sprayed with 1000-1500 times or 40% of good labor EC is 1000-1500 times and soft water is 4000 times. Spray it once more in five or six days to eliminate the nymph.
