Embodiment Construction

[0022] Example 1

[0023] 3 parts of 40% diazinon EC, 3 parts of 50% dichlorvos EC, 2 parts of tea polyphenols, 1 part of astragalus polysaccharide, 2 parts of forsythin, 2 parts of terbuthiuron, 1 part of nitenpyram, fly poison Phosphorus 3 parts.

[0024] Instructions,

[0025] A. Take the original solution for later use: the components of the original solution are: 40% diazinon EC, 50% dichlorvos EC, tea polyphenols, astragalus polysaccharide, forsythiaside, terbuthiauron, nitenpyram, and muscarin;

[0026] B. The spraying cycle is 3-5 times, spraying once every 3 days. In the early stage of the disease, because the eggs are mainly produced on the back of the leaves, use the stock solution to dilute to 1000 times the volume multiple, and then spray;

[0027] C. In the adult stage, dilute the stock solution to a volume multiple of 1300 times, and then spray.

[0028] D. When the temperature is higher than 26 degrees Celsius, it is necessary to increase the spraying time a...

Abstract

The invention discloses an application method of a compound pesticide for controlling vegetable leaf miner, which comprises the following steps: A. taking raw liquor for later use, wherein the raw liquor is composed of 40% diazinon missible oil, 50% dichlorvos missible oil, tea polyphenol, radix astragali polysaccharide, phillyrin, tebuthiuron, nitenpyram and coumaphos; B spraying the raw liquor 3-5 times every 3 days, wherein in the disease development early stage, since the ova are mainly produced to the leaf back, the raw liquor is diluted to 1000 times by volume and then sprayed; C. in the imago stage, diluting the raw liquor to 1300 times by volume, and spraying; and D. after the temperature is higher than 26 DEG C, increasing the spraying time and period, and continuously spraying 4-5 times every 4 days. The application method is simple; the used product is simple in proportioning and convenient to use, and has favorable control effect on leaf miner; and the control effect is enhanced by 15-18% as compared with the traditional pesticide.

Description

[0001] technical field [0002] The invention belongs to the technical field of vegetable pest control, and in particular relates to a method for using a compound drug for preventing and controlling vegetable leafminers. [0003] Background technique [0004] Leaf miner body length 4 ~ 6 mm, taupe. The male fly has hairs under the front edge, the legs and tibias are grayish yellow, the tarsus is black, and the hind tibia has 3 bristles. Eggs are white, oval, 0.9 mm x 0.3 mm in size, and mature larvae are about 7.5 mm long, wrinkled and black-yellow. Pupa, about 5 mm long, oval in shape, light yellowish brown at first, then reddish brown, and dark brown before eclosion. Leafminer is one of the main pests and diseases of vegetables. Its larvae sneak under the epidermis of the host leaves, zigzag through, and feed on green tissues, forming irregular gray-white linear tunnels. When the damage is serious, almost all the leaf tissue is damaged, and the leaves are covered with ...
