Problems solved by technology

[0004] In practice, there are several major problems in the control of citrus psyllids by aircraft. One is the guarantee of the control effect of citrus psyllids in citrus orchards and the surrounding environment; the other is the problem of reducing fog drop drift and protecting the environment during aircraft control, especially for citrus planting. The safety of fish ponds and bees in the park; the third is how to delay the emergence of citrus psyllid resistance in the process of repeated pesticide application

Embodiment 1

[0046] In the first ten days of March 2015, aircraft control of citrus psyllid adults in spring was carried out in Anyuan County, Jiangxi Province, covering an area of ​​about 20,000 mu. The Feifang citrus orchard is Gannan navel orange, the variety is Newhall, the planting density is about 50 plants / mu, the tree age is 8-12 years, the tree height is 2-2.5m, the tree diameter is about 20cm, and it is in the early spring shoot.

[0047] 1. Anti-flying time: The citrus psyllid (Diaphorina citri) is in the blooming period of overwintering adults.

[0048] 2. Aircraft type and flight defense operation parameters

[0049] The aircraft is the Little Squirrel AS350B3 helicopter produced by Eurocopter, with a liquid carrying capacity of 600kg. The effective spraying range of the aircraft is 30m, the flying speed is 90km / h, the flying height is 7-10m from the crop canopy height, the spraying volume per mu is 500ml / mu, and the spraying time of the plane is about 21 minutes.

Embodiment 2

[0072] From June 2nd to 3rd, 2015, the summer shoot control of citrus psyllid was carried out in Xunwu County, Jiangxi Province, covering an area of ​​more than 15,000 mu. The Feifang citrus orchard consists of Wenzhou tangerine Miyagawa and Gannan navel orange Newher. The trees are 8-10 years old and 2-2.5 meters high. They are in the young fruit stage of summer shoots.

[0073] 1. Anti-flying time: Citrus psyllid (Diaphorina citri) is in the peak adult development period of summer shoots, and eggs, nymphs, and adults emerge concurrently.

[0074] 2. Aircraft type and flight defense operation parameters

[0075] The aircraft is an Enstrom EN480B helicopter produced by Enstrom Helicopters, with a liquid capacity of 350L. The effective spray width of the aircraft is 26m, the flight speed is 100km / h, the flight height is 7-10m from the height of the crop canopy, the spray volume per mu is 500ml / mu, and the spraying time of the aircraft is about 11 minutes.

Abstract

The invention provides a method for preventing and curing diaphorina citri by virtue of an airplane. The method comprises the step of uniformly spraying medicaments by virtue of the airplane to spring shoots, summer shoots, autumn shoots or winter shoots in each year, wherein the medicaments include a medicament A, a medicament B and 0.1%-0.5% of a 'Feibao' flight-prevention aid. By virtue of the method, the prevention effect of the diaphorina citri is guaranteed, meanwhile, the safety of the ecological environment of a citrus orchard is guaranteed, the preventing and curing costs are lowered, the use amount of pesticides is reduced, the drug resistance of the diaphorina citri is effectively delayed, and the sustainable development of the ecological system of the citrus orchard is guaranteed.

Description

technical field [0001] The invention relates to a control method for citrus psyllids, belonging to the technical field of pest control. Background technique [0002] The citrus psyllid is the main pest of citrus and other Rutaceae plants in the shoot stage. The adults and nymphs not only suck the young leaves of citrus, but more importantly, they are the only natural vector insects for citrus huanglongbing. Since there are no agents, methods and resistant germplasm resources for citrus huanglongbing, the citrus psyllid has become the main reason for the rapid spread of citrus huanglongbing and the difficulty in controlling it. [0003] For the control of citrus psyllid, the traditional ground control gradually tried to control citrus psyllid by spraying pesticides by aircraft. Aircraft spraying provides the possibility for the prevention and control of citrus huanglongbing and its spread: 1. It provides the possibility of quickly reducing the population base of citrus psyll...
