Effect test
Embodiment 1
[0017] Embodiment 1 A kind of slow-release drug tape for preventing and treating the cotton aphid, comprising a strip-shaped permeable membrane, on which permeable membrane length is coated with 0.5 gram of pyrithidine powder, and said pyrithipate powder is composed of imidacloprid and clothianidin Oxyzine is mixed at a mass ratio of 1:1, and then the permeable membrane is sealed and rolled into a roll.
[0018] When in use, first remove the top soil at the root neck of the trunk by about 5cm. Then wrap the slow-release drug belt around the base of the trunk, fix the joint with adhesive tape, and then cover with soil. Then water the root neck, 1 liter per plant. After treatment, the effect of the medicine gradually appeared after 3 weeks, and the control effect could reach more than 90% after 45 days. The validity period can reach more than 180 days.
Embodiment 2
[0019] Example 2 Field experiment of controlling apple cotton aphid with slow-release drug tape
[0020] The test was set in the orchard of Shuimo Village, Mazhai Town, Zhongyuan District, Zhengzhou City, Henan Province. The trees were 16 years old, the distance between plants and rows was 4×4 meters, and the height of the trees was about 3 meters. The apple cotton aphid is in the initial stage.
[0021] (1) Test drug: the test drug imidacloprid · thiamethoxam wettable powder, prepared in the laboratory, after the preparation, the powder was sealed in a wood pulp paper tape, the control drug 10% imidacloprid wettable powder, Hebei Weiyuan Biotechnology Co., Ltd. production, commercially available.
[0022] (2) Experimental design: plot area: 2 trees per plot, 32 square meters. Number of replicates: 4 replicates per treatment.

Abstract
The invention relates to a slow-release pesticide band for controlling woolly apple aphid and a method for the same. The pesticide band comprises a belt-shape permeable membrane which is coated or sprayed with feldene powder, wherein the feldene powder is prepared by mixing imidacloprid with thiamethoxam according to mass ratio of 1:(0.25-4). The control method comprises the following steps of: digging surface soil at the root neck of a trunk for 4-6cm; then laying the slow-release pesticide band at the root neck for a circle; restoring the surface soil; quantitatively watering the root neck of each plant by 1-2 liters; and enabling effective components of the pesticide to seep a pesticide membrane along with water current, to be absorbed by bark and flow to each part of a tree body along with a plant liquid in a sieve tube. According to the slow-release pesticide band disclosed by the invention and powdery pesticide is packaged in the pesticide band, is laid to the root neck of the tree body; effective components of pesticide are slowly seeped into the bark by watering or rainfall wetting and are conducted to each part of the tree body along with a phloem part. The method has the advantages of concentrated pesticide application, continuous slow release, continuous control action on the pests, simpleness and convenience for operation, favorable control effect and lower pollution to the environment than that of chlorpyrifos spray.
Description
technical field [0001] The invention relates to the field of agricultural pest control, in particular to a slow-release drug belt and method for controlling apple cotton aphid. Background technique [0002] Apple cotton aphid is a worldwide quarantine pest. It has spread rapidly in my country in recent years and has become an important control object in major apple producing areas. At present, the organophosphorus pesticide chlorpyrifos is sprayed in most cases to prevent and control the apple aphid. It needs to be sprayed 2 to 3 times with 1500-2000 times of 40% chlorpyrifos EC every year. As the apple aphids damage the trees every year, spraying chlorpyrifos can only control the damage for a short time, and chlorpyrifos is a broad-spectrum pesticide, which is very lethal to natural enemies of pests. Continuous use will not only increase the resistance of pests, but also kill a large number of people. Natural enemies, causing outbreaks of secondary pests, the current very ...
