Embodiment Construction

[0010] 1. Agricultural control measures. Combine autumn application of basal fertilizer or winter irrigation before overwintering to thoroughly clean the dead branches, fallen leaves and various weeds in the garden, and scrape off all kinds of old bark before germination.

[0011] 2. Biological control measures. By using sex traps, sweet and sour traps, and branch coatings to control heartworms and aphids during the period from late April to June when the two parasitic wasps lay eggs and parasitic wasps. Avoid spraying with drugs. To protect the jumping bee.

[0012] 3. Chemical control measures. Choose 25% Aketai 5000-6000 times liquid, or 10% imidacloprid WP 1500-2000 times liquid, 5% Acetamiprid soluble powder 2500-3000 times liquid, 52.25% Nongdile EC 1500-2000 times liquid, Each medication can be added 6000 times the natural brassinolide.

Description

technical field [0001] The invention relates to the field of fruit forest planting, in particular to a new technology for winter control of pear psyllids in pear orchards. Background technique [0002] Pear psyllid, also known as pear lice, sucks the juice of pear buds, leaves and young shoots with adults and nymphs, and mainly does damage to nymphs. After the leaves are damaged, brown spots will appear, and in severe cases, the whole leaves will turn brown, causing early leaf defoliation. The nymphs secrete a large amount of mucus, which induces soot. The new shoots are stunted after being killed. After the fruit is damaged, the surface is smoked, which affects the appearance quality. The damage of pear psyllid weakens the tree vigor, damages the yield of the year, and hinders the differentiation of flower buds, causing great losses to the yield of the coming year. Contents of the invention [0003] In order to solve the technical problems in the traditional sunflower...
