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

[0026] 1. Hang yellow sticky insect board

[0027] 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.

[0028] 2. Prepare 15% paclobutrazol 2000 times solution

[0029] 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.

[0030] 3. Spray liquid medicine

[0031] 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 branche...

Abstract

The invention discloses a method for preventing and controlling pear gall midges, which comprises the following steps: (1) determining the time for hanging a yellow sticky insect board in a pear orchard; ~2.0m, the hanging density is 15 tablets / mu; (3) The time and concentration of the spraying liquid are determined: the pear varieties are sprayed during the flowering stage, and 15% paclobutrazol wettable powder is prepared at 2000 times; (4) The liquid is sprayed : Spray the prepared paclobutrazol solution on the top of the branches of adult pear trees. Using the method can effectively reduce the harm of pear gall midges to young leaves and branch tips, reduce one or two spraying times throughout the year, reduce production costs, reduce environmental pollution, and be ecological and environmentally friendly, and the method is easy to operate and simple to operate. The problem of harm caused by pear gall midges in pear production can be effectively reduced through the treatment of the invention.

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...
