Method for preventing and controlling insect damage of grape pseudococcus comstocki

Abstract

The invention discloses a method for preventing and controlling insect damage of grape pseudococcus comstocki and relates to the technical field of grape disease and insect prevention and control. The method comprises the following steps of in autumn, timely picking dry branches, fallen leaves and weeds from a grape garden, and burning or deeply burying the dry branches, the fallen leaves and the weeds together to kill hibernating eggs; protecting lacewings and ladybirds which serve as the natural enemy of pseudococcus comstocki; in winter, scraping off cracked skin on branches and tendrils, removing hibernating egg bags by using a hard-hair brush, and burning the hibernating egg bags together; before, young leaves sprout, spraying a lime sulfur with the baume degree of 15; during a growing period, spraying one of 1,800 times of Lorsban emulsifiable concentrate with the concentration of 48 percent and 1,800 times of Nurelle-D 505 emulsifiable concentrate with the concentration of 52 percent onto the ground. The preventing and controlling way to the grape pseudococcus comstocki is reasonable, the step is simple, the problem of pseudococcus comstocki damage can be radically solved, meanwhile, the effect of preventing and controlling the pseudococcus comstocki 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 pest control, in particular to a method for preventing and controlling grape mealybug 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 mealybug is one of the main diseases in the production of grapes in my country. There is a distribution, adults and nymphs suck the juice of fruits, leaves and twigs. After the fruit tree is killed, the fruit surface and leaf surface will be moldy, the growth and...
