Embodiment 1

[0020] Example 1: Weigh 35 kg of hypertonic fenoxycarb emulsifiable concentrate, 15 kg of imidacloprid, and 6 kg of sodium alkylbenzene sulfonate, and mix them uniformly to prepare an insecticide for controlling pine stem borer.

[0021] The field efficacy test of pine borer was carried out with the insecticide for controlling pine borer obtained in Example 1, and 1000, 1500 times of liquid were used for uniform spraying respectively, and a single dose or two of them were used as comparison, as shown in table 1.

[0022] Table 1 is the experimental results of the control of pine borer insecticides in Chengwan Township, Tongbai County.

[0023]

Embodiment 2

[0024] Example 2: Weigh 40 kg of hypertonic fenoxycarb emulsifiable concentrate, 20 kg of imidacloprid, and 7 kg of sodium alkylbenzene sulfonate, and mix them uniformly to prepare an insecticide for controlling pine borer.

[0025] Carry out the field drug effect test of pine borer with the insecticide for controlling pine borer obtained in Example 2, adopt 1000, 1500 times of liquid to spray evenly respectively, adopt single dose or two of them as comparison simultaneously, as shown in table 2.

[0026] Table 2 is the experimental results of the control of pine borer insecticides in Huilong Township, Tongbai County.

[0027]

Embodiment 3

[0028] Example 3: Weigh 45 kg of hypertonic fenoxycarb emulsifiable concentrate, 20 kg of imidacloprid, and 7 kg of sodium alkylbenzene sulfonate, and mix them uniformly to prepare an insecticide for controlling pine borer.

[0029] The field efficacy test of pine borer was carried out with the insecticide for controlling pine borer obtained in Example 3, and 1000 and 1500 times of liquid were used to uniformly spray respectively, and a single dose or two of them were used as comparison, as shown in table 3.

[0030] Table 3 is the experimental results of the control of pine borer insecticides in Zhuzhuang Township, Tongbai County.

[0031]

[0032] The experimental results show that ① the effect is better: the combination of hypertonic fenoxycarb EC and imidacloprid to control pine shoot borer does not harm natural enemies, does not cause damage to the environment, and has a good control effect on pests. According to observations, one day after spraying, the 1-2 instar nym...

Abstract

The invention discloses a prevention and control method for dioryctria splendidella. The prevention and control effect can be achieved by spraying pesticide on pine trees in April and July each year. The pesticide is a mixture of high permeation fenoxycarb missible oil, imidacloprid and sodium alkyl benzene sulfonate. The mass ratio of high permeation fenoxycarb missible oil to imidacloprid to sodium alkyl benzene sulfonate is 30-60 to 10-25 to 5-10. The mass ratio of pesticide used during spraying to water is 1 to 1000-2000. Compared with the prior art, emphasis prevention and contrl are selected to be conducted during the larval phase of dioryctria splendidella in April and July each year; meanwhile, the pesticide obtained according to a reasonable formula of high permeation fenoxycarb missible oil, imidacloprid and sodium alkyl benzene sulfonate is good in dioryctria splendidella prevention and control effect, low in pesticide cost and capable of being applied and popularized in a large area.

Description

technical field [0001] The invention relates to a technology for preventing and controlling pine tree branch insect pests, in particular to a method for preventing and controlling the pine tree pest pine shoot borer. Background technique [0002] Pine tip borer, also known as pine tip borer, mainly harms the pine tips of Pinus massoniana, Chinese pine, black pine, Huashan pine, etc. Utilization value and green ornamental effect. There are two generations a year, and the larvae live through the winter in the boreholes of the damaged branches or in the cones and wounds at the base of branches. From late March to early April of the following year, the overwintering larvae began to continue to eat downwards in the damaged shoots, and some of them transferred to damage new shoots. In the first ten days of May, the larvae mature one after another and pupate in the killed shoots. Eclosion occurs in late May. Eggs are laid on the young needles or the base of the sheaths, and als...
