Problems solved by technology

[0003] However, in recent years, the peach borer has seriously affected the yield of Sophora japonica, especially in relatively dry years, the damage of the peach borer is particularly serious, ranging from 30% to 80% in severe cases, making farmers who have worked hard for a year very profitable. Less, or even a double loss of work and cost
The traditional method of preventing and controlling the chrysanthemum moth is mostly sprayed with pesticides after the chrysanthemum is harmed by the peach moth. Since the best time to kill the peach moth has not been grasped, the effect is not obvious, and the damage of the peach moth is still very serious. serious

Embodiment 1

[0025] A method for preventing and controlling the Chinese pagoda tree moth borer, the operation steps are as follows:

[0026] (1) Eliminate overwintering larvae: Before the overwintering larvae pupate in mid-November each year, remove the remains of the host plant, scrape off the warped skin, and burn them in a centralized manner to reduce the source of insects;

[0027] (2) In winter, the use of quicklime water with a mass concentration of 40% is used to smear and dry, and the height of smearing is 18 to 20 cm, so as to prevent and control the transfer of larvae from soil to branches;

[0028] (3) Trapping and killing adults: light a black light in the garden or use sweet and sour solution to trap and kill adults; the sweet and sour solution is obtained by mixing white sugar and rice vinegar at a mass ratio of 1:0.7 and dissolving them in tap water twice the total mass of sugar and rice vinegar ;

[0029] (4) Kill the peach borer at the best time: Spray 3000-fold diluted i...

[0032] A method for preventing and controlling the Chinese pagoda tree moth borer, the operation steps are as follows:

[0033] (1) Eliminate overwintering larvae: Before the overwintering larvae pupate in mid-November each year, remove the remains of the host plant, scrape off the warped skin, and burn them in a centralized manner to reduce the source of insects;

[0034] (2) In winter, use quicklime water with a mass concentration of 50% to smear dry, with a dry height of 10-12 cm, to prevent and control the transfer of larvae from soil to branches;

[0035] (3) Trapping and killing adults: light a black light in the garden or use sweet and sour solution to trap and kill adults; the sweet and sour solution is obtained by mixing white sugar and rice vinegar at a mass ratio of 1:0.7 and dissolving them in tap water twice the total mass of sugar and rice vinegar ;

[0036] (4) Kill the peach borer at the best time: Spray 3000-fold diluted imidacloprid and organic silicon sprea...

Embodiment 3

[0039] A method for preventing and controlling the Chinese pagoda tree moth borer, the operation steps are as follows:

[0040] (1) Eliminate overwintering larvae: Before the overwintering larvae pupate in mid-November each year, remove the remains of the host plant, scrape off the warped skin, and burn them in a centralized manner to reduce the source of insects;

[0041] (2) use the quicklime water that mass concentration is 45% to carry out coating dry in winter, coating dry height 14~26cm, prevention and control larva transfers from soil to branch;

[0042] (3) Trapping and killing adults: light a black light in the garden or use sweet and sour solution to trap and kill adults; the sweet and sour solution is obtained by mixing white sugar and rice vinegar at a mass ratio of 1:0.7 and dissolving them in tap water twice the total mass of sugar and rice vinegar ;

[0043] (4) Kill the peach borer at the best time: Spray 3000-fold diluted imidacloprid and organic silicon spre...

Abstract

The invention discloses a method for preventing and controlling dichocrocis punctiferalis of golden sophora japonica. The method comprises the following operation steps of (1) removing overwintering larvae to reduce the pest source; (2) coating the trunks of golden sophora japonica trees with quick lime water in winter, wherein the coating height is 10-20 cm; (3) trapping and killing adult dichocrocis punctiferalis; (4) spraying a mixed pesticide liquid of imidacloprid and an organosilicone synergist in time when new shoots of the golden sophora japonica trees grow to 10+ / -2 cm in length aftergermination; (5) mixing deltamethrin emulsifiable concentrates with the organosilicone synergist to dilute a pesticide liquid spray when the pest (egg) plant rate is 20% or above. The time when new shoots of the golden sophora japonica trees grow to 10+ / -2 cm in length in spring is the time for overwintering dichocrocis punctiferalis to climb out of soil for excretion, feeding and ovulation. Therefore, the time is the best time to kill dichocrocis punctiferalis by spraying pesticide for the first time, not only can the adult dichocrocis punctiferalis be killed to prevent ovulation of the dichocrocis punctiferalis, but also eggs of the dichocrocis punctiferalis are killed, so that a large number of dichocrocis punctiferalis pests are killed from the source.

Description

technical field [0001] The invention relates to the technical field of methods for preventing and controlling crop production diseases and insect pests, in particular to a method for preventing and controlling the Chinese pagoda tree moth borer. Background technique [0002] Sophora japonica L. is the dried flower bud of Sophora japonica L., a leguminous plant. It is a characteristic Chinese medicinal material. Its active ingredient rutin has anti-inflammatory, antispasmodic, anti-ulcer, anti-bacterial, fungal and virus-absorbing properties. effect. Jinhuai is a branch of many varieties of pagoda tree. It grows in northern Guangxi and southern Hunan. The content of rutin in Jinhuai rutin in Quanzhou County is between 35% and 37%, some even as high as 46%, which is much higher than the standard limit of 15% in "Chinese Pharmacopoeia" (2005 edition). Quanzhou is the best place to produce high-quality Huai Mi, and has irreplaceable geographical advantages. The special natural...
