Method for preventing and controlling insect damage of grape node-lacking eriophyidae

Abstract

The invention discloses a method for preventing and controlling insect damage of grape node-lacking eriophyidae and relates to the technical field of grape disease and insect prevention and control. The method comprises the following steps of when a nursery stock is introduced from an ill area, soaking the nursery stock in water with the temperature of 32 to 38 DEG C for 7 to 9 minutes, and soaking the nursery stock in the water with the temperature of 60 DEG C to kill latent eriophyidae; combining the step of trimming in winter, and after cutting off damaged branches and tendrils, burning the branches and tendrils to kill a hibernating insect source; in the June to July every year, checking young branches for one time every 7 days, and if damaged branches and tendrils are found, timely cutting off the damaged branches and tendrils; in spring, when sprouts are grown to 1cm, spraying a drug onto the sprouts, wherein the drug is selected from one of lime sulfur with the baume degree of 0.4, 250 times of crystal lime sulfur agent with the concentration of 50 percent, 1,800 times of pyridaben emulsifiable concentrate with the concentration of 20 percent, 1,500 times of fenpyroximate emulsifiable concentrate with the concentration of 5 percent, 1,800 times of bifenthrin emulsifiable concentrate with the concentration of 20 percent, 1,500 times of hexythiazox emulsifiable concentrate with the concentration of 5 percent and 2,000 times of chlorpyrifos emulsifiable concentrates with the concentration of 50 percent. The problem of node-lacking eriophyidae damage can be radically solved, meanwhile, the effect of preventing and controlling the node-lacking eriophyidae is also obvious, and the healthy and strong growth of grapes is promoted.

Description

technical field [0001] The invention relates to the technical field of prevention and control of grape diseases and insect pests, in particular to a method for preventing and controlling insect pests of grape gnats. Background technique [0002] Grapes, which produce almost a quarter of the world's fruits; are highly nutritious and can be made into grape juice, raisins and wine. The planting of grapes will have different moisture and sweetness due to climate conditions and land properties. Therefore, the sweetness and variety of grapes are very different across the country. The most common way to eat grapes at this stage is to prepare raisins, wine and Grape juice, in the actual planting of grapes, the harm of diseases and insect pests is huge. Grape gall mite is one of the main diseases in grape production in China. Grape gall mite is also called grape rust tick and grape felt. It is distributed in most of the provinces, municipalities, and autonomous regions in China. Adu...

The planting of grapes will have different moisture and sweetness due to climate conditions and land properties. Therefore, the sweetness and variety of grapes are very different across the country. The most common way to eat grapes at this stage is to prepare raisins, wine and Grape juice, in the actual planting of grapes, the harm of diseases and insect pests is huge. Grape gall mite is one of the main diseases in grape production in China. Grape gall mite is also called grape rust tick and grape felt. It is distributed in most of the provinces, municipalities, and autonomous regions in China. Adult mites and nymphs mainly damage the leaves of grapes. When serious, they also damage young shoots, young fruits, tendrils, and pedicels. When the leaves are damaged, the backs of the leaves appear pale Stain, the leaf tissue is stimulated to grow dense hairs and presents felt-like plaques, the spots are often limited by larger leaf veins, the hairs are grayish white at first, and gradually turn into tea brown to dark brown, and swollen and concave-convex on the leaf surface Uneven fading spots, insect spots on young leaves are mostly light red, and when severe, leaves are wrinkled and dry, and flower stalks, tender fruits, tender stems, and tendrils are damaged and cause growth stagnation. plan is unreasonable
