Tianniu is a general term for insects of the multi-food suborder Tianniu family, with many species, more than 20,000 species in the world, and is widely distributed around the world as the main pest on various forest fruit trees such as pine, cypress, willow, elm, walnut, citrus, apple, peach and tea. Since the Celestial Bull mainly harms the inside of the forest with larvae, it is very difficult to control. Today, Xiaobian recommends an excellent medicine for the prevention and treatment of Tianniu, which has good effect and long effectiveness, and can be used for more than 90 days at a time.
Hazard characteristics of Tianniu
Tianniu occurs once a year, mainly with larvae overwintering in trees, the larvae begin to be active in March of the following year, in mid-April, the larvae do pupae, generally 20 to 30 days after feathering adults, adults mainly eat the bark after feathering, generally 15 days after feathering can mate and lay eggs, lay eggs on the lateral branches of the lower part of the main trunk, hatch into larvae 10 to 14 days after egg laying, the larvae first moth 10 mm above the branches, and then turn around and eat downwards, and gradually go deep into the marrow, each moth 5 to 6 cm, 1 fecal hole to the outside , the fecal holes are all arranged downward in the same directional order. As the larvae grow, the distance from the fecal vents becomes farther and farther away. The moths in the larvae can reach 1.7 to 2 meters long in their lifetime, and the adults mainly eat the bark of the tree, and can mate and lay eggs several times a year. Adult worms can live up to 40 to 50 days.
Introduction to the agent
This agent is thiamethoxine, which is a new type of nicotinic insecticide developed by the German company Bayer, which has a very good touch and gastric toxicity and strong systemic conductivity. Mainly acting on the nervous system of the pest, interfering with the normal conduction of the insect nervous system, causing the blockage of the nerve channel, causing a large accumulation of acetylcholine in the pest, so that the insect is abnormally excited, the whole body spasms, paralysis and death. It is currently the best medicine for the prevention and control of Tianniu.
Main features
(1) Wide spectrum of insecticidal: Thiamethoxam is mainly used for the control of stinging insect pests and chewing pests, in addition to a good killing effect on the tianniu, it can also be used to control greenhouse whiteflies, tobacco whitefly, aphids, thrips, planthoppers, pear lice, potato beetles, apple weevils and rice water weevils, wheat red suckers, leafminer moths, apple midge moths and other pests.
(2) Good systemicity: thiamethoxam has good internal conductivity, after the spray of the agent, it can be absorbed by the leaves and conducted to various parts of the plant to achieve the purpose of killing pests.
(3) Good quick-acting: thiamethoxam mainly acts on the nervous system of pests, so that pests are in a state of excitement, and once the pests are in contact with the agent, they can kill the pests in a few minutes.
(4) Long period of effectiveness: After thiamethoxam is absorbed by plants, it can exist in the plant for a long time to achieve the purpose of killing pests for a long time.
(5) Safety to the environment: Thiamethoxam is the only neonicotinoid insecticide that is low toxic to bees and low to fish and other aquatic animals, and has good environmental and water safety.
Suitable for crops
Thiamethoxine control tianniu is mainly suitable for pine trees, cypress trees, willow trees, poplar trees, mulberry trees, elms, apple trees, pear trees, peach trees, walnuts, citrus and other forest trees, fruit trees, ornamental trees and so on.
Prevention and control objects
It can be used to prevent and control Xingtian Bull, Mulberry Tianniu, Pine Brown Tianniu, Bare Shoulder Star Tianniu, Peach Neck Tianniu, White Tendon Tianniu, Red Edge Tianniu, Cloud Spot White Strip Tianniu, Bamboo Edge Tiger Tianniu, Deep Mountain Tianniu, etc.
How to use
Master the use of drugs in the peak period of Tianniu feathering, 3% thiamethoxine microcapsular suspension 2000-3000 times liquid, using a motorized sprayer for interforest spraying. After 2 hours of application, Tianniu began to die in large numbers, and the prevention and control effect after 24 hours could reach more than 90%. When used in rainy conditions, it can be controlled for about 40 days, and when used in low rain conditions, it can be effective for up to 90 days. The number of applications and dosages have been greatly reduced.
