Embodiment example 1

[0024] On February 28, 2013, yellow sticky boards were hung in Jinshui No. 1 pear orchard to trap and kill overwintering adults. On April 1, 15% paclobutrazol WP 2000 times liquid was sprayed on the whole tree of Jinshui No. 1 pear tree to promote the growth of new pear trees. Early maturation and aging can avoid the peak period of the emergence of the second-generation pear gall midge during the growth period of young leaves, and the effect of reducing the damage of pear gall midges is very significant.

specific Embodiment approach

[0025] 1. Hang yellow sticky board

[0026] On February 28, 2013, a yellow sticky insect board was hung in the pear orchard. The size of the yellow sticky insect board is 25cm×40cm, and the hanging height is 1.5~2.0m. First, split the top of the 2.0m long bamboo pole, open the sticky insect board, insert it into the split bamboo pole, and then insert it into the pear orchard. The hanging density is 15 pieces / mu, evenly distributed.

[0027] 2. Prepare 2000 times solution of 15% paclobutrazol

[0028] Accurately weigh 10g of 15% paclobutrazol wettable powder, mix it into 20kg of water, stir thoroughly for 2 minutes, and paclobutrazol is fully dissolved. Shake the solution well before spraying.

[0029] 3. Spraying liquid medicine

[0030] On April 1, 2013, 15% paclobutrazol wettable powder 2000 times was evenly sprayed on pear tree 7-year-old Shengjinshui No. 1 with an artificial sprayer. It is better to spray the medicinal liquid evenly with water droplets on the branches...

Abstract

The invention discloses a method for controlling pear gall midges. The method comprises the following steps: (1) determining time for hanging yellow sticky coloured cards in a pear garden; (2) hanging the yellow sticky coloured cards in the pear garden, wherein the specification of each yellow sticky coloured card is 25cm*40cm, the hanging height is 1.5-2.0m, and the hanging density is 15 pieces per mu; (3) determining pesticide spraying time and the pesticide concentration: spraying in the blossom fall period of pear species, and preparing 2000 times solution of 15 percent of paclobutrazol wettable powder; (4) spraying the pesticide: spraying the prepared solution of the paclobutrazol wettable powder to the top ends of branches of adult pears. By using the method, the harm of the pear gall midges to tender leaves and shoots can be effectively reduced, pesticide spraying is reduced all year round for 1-2 times, the production cost is reduced, and the environmental pollution is reduced; the method is ecological and environmentally friendly, easy to implement, and simple in operation; through the treatment of the method disclosed by the invention, the problem of the harm of the pear gall midges during pear production can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for preventing and treating pear gall midges, which can effectively solve the problem that pear varieties are harmed by pear midges in pear scientific research, breeding and production. Background technique [0002] pear gall midge [ Dasineura pyrivora (Bouche)], also known as pear leafroller gall midge, pear bud maggot, pear leaf maggot, pear red sand worm, belongs to Diptera ( Diptera ) Galliidae ( Cecidom yiidae ). It was once listed as one of the third-class quarantine objects of imported harmful organisms in my country. Since the 1980s, with the prosperity and development of domestic trade, pear gall midge spread to pear producing areas in my country very quickly. At first, it only occurred in the northern pear producing areas, such as Henan, Anhui, Hebei and other provinces as a secondary pest, and it is a newly recorded pest in Chi...
