Problems solved by technology

The damage mode and damage symptoms of grape thrips are: nymphs or adults suck the juice of young fruit, young leaves and new shoot epidermal cells with file-sucking mouthparts. After the leaves are damaged, the chlorophyll is destroyed, yellow spots appear, the leaves become smaller and curled, and even dry or perforation, the growth of new shoots is inhibited after being damaged, and the damaged part of the young fruit loses water and shrinks, forming small black spots, which expand with the increase of the fruit body, presenting corky brown rust spots of different shapes, which will cause cracking in severe cases. Affects the appearance of the fruit body and reduces the value of the product
[0003] At present, the prevention and control methods of grape thrips are mainly the combination of chemical pesticide control, biological pesticide control and physical trapping and killing. The use of too many chemical pesticides will lead to a large reduction in pesticide residues, environmental pollution and natural enemies of thrips , can not meet the pollution-free planting standards, therefore, it is necessary to seek a green method to prevent and control thrips, so as to achieve the purpose of pollution-free grape planting

Embodiment 1

[0025] A kind of method for preventing and controlling grape thrips of the present embodiment comprises the following steps:

[0026] (1) After cleaning up all the weeds in the vineyard in winter, mix botanical pesticides and water with a volume ratio of 1:10 and apply them to the soil to kill the overwintering thrips in the soil. The trunk of the grape is coated with sticky shellac with a width of 5 cm around the bark; wherein, the preparation method of the botanical pesticide is: 25 parts of tobacco, 30 parts of pyrethrum, 10 parts of red eucalyptus, 8 parts of patchouli After crushing 12 parts of rosemary and 12 parts of rosemary, add 5 times by weight of ethanol with a volume fraction of 85% to reflux for extraction for 1 hour, repeat the extraction twice, and combine the extracts to obtain final product;

[0027] (2) arranging blue sticky boards to trap and kill thrips in the vineyard, the sticky boards are arranged at 20cm above the crown of the vine, and the hanging dis...

Abstract

The invention discloses a method for preventing and controlling grape thrips, and relates to the technical field of fruit tree pest control. According to the occurrence and damage laws of the thrips,the thrips in soil of a vineyard are restrained and killed by using a botanical pesticide, insect-sticking glue and insect-sticking plates are reasonably arranged to inhibit the thrips, luring plantssuch as Japanese thistle herb or root and white radish are planted to kill the thrips, and nectariferous plants such as clover, perilla frutescens and marjoram are planted to protect natural enemies against the thrips. Through the series of technical means, the harm of the grape thrips is effectively reduced, the goal of pollution-free planting is achieved, and the quality of grapes is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of prevention and control of fruit tree diseases and insect pests, in particular to a method for preventing and controlling grape thrips. 【Background technique】 [0002] Grape thrips belongs to Thysanoptera Thripidae Thripidae subfamily Thrips, also known as thrips tobacco, thrips cotton, thrips onion, is one of the main pests of grapes. In addition, there are several types of thrips that harm grapes, such as thrips yellow-breasted, thrips cuckoo, thrips rhododendron, and thrips eight-sectioned. The main damage period is the flowering period and veraison period of grapes. Thrips generally live through the winter on weeds or in the soil. In spring, they move to the young leaves of grapes to reproduce and cause damage. Thrips can also be found before the leaves of grapes fall in early and mid-December. The peak period of thrips occurrence is from May to early June and August-October these two periods. The ...
