Method for preventing and controlling insect damage of grape lycorma delicatula

Abstract

The invention discloses a method for preventing and controlling insect damage of grape lycorma delicatula and relates to the technical field of grape disease and insect prevention and control. The method comprises the following steps of removing weeds and fallen leaves in a field in early spring, and burning or deeply burying the weeds and fallen leaves together to reduce insect sources; combining winter trimming and fruit garden management to scrap hibernating egg masses from tendrils; during an adult insect emergence period, vibrating a grape frame at nightfall every 5 days to shake adult insects off, artificially capturing the adult insects, and cleaning the adult insects together; applying an organic fertilizer, enhancing fruit garden management, and timely draining water and trimming; during an adult insect and nymph emergence period, spraying one of 1,300 to 1,800 times of imidacloprid wettable powder with the concentration of 3.5 percent, 6,500 to 7,500 times of Confidor thick solvent with the concentration of 25 percent, 2,000 to 2,500 times of acetamiprid emulsifiable concentrate with the concentration of 3 percent, 800 times of dichlorvos emulsifiable concentrate with the concentration of 50 percent and 1,600 times of trichlorfon with the concentration of 90 percent to kill the insects. The preventing and controlling way to the grape lycorma delicatula is reasonable, the step is simple, the problem of lycorma delicatula damage can be radically solved, meanwhile, the effect of preventing and controlling the lycorma delicatula 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 grape disease and insect control, in particular to a method for preventing and controlling grape variegated cicada pests. 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 spotted-coated wax cicada is one of the main diseases in my country's grape production. There are distributions. Adults and nymphs damage grape shoots, leaves and young fruits. The damaged leaves are water-soaked and lose greenish-yellow spots. General...

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 spotted-coated wax cicada is one of the main diseases in my country's grape production. There are distributions. Adults and nymphs damage grape shoots, leaves and young fruits. The damaged leaves are water-soaked and lose greenish-yellow spots. Generally, leaf tips and leaf edges are the most severely damaged. In severe cases, the extension of new shoots is inhibited. The leaves become smaller, curled into a cup shape or misshapen, even dry, and sometimes perforated. The damaged young fruit forms small black spots on the fruit surface at the early stage, and becomes corky brown rust spots of different shapes as the young fruit grows. Affect the appearance of fruit grains, reduce the commodity value, and even cause fruit cracking in severe cases. However, the existing control technology for the control of the spotted-coated wax cicada is unreasonable.
