It is an important pest on citrus, grapefruit and persimmon trees, commonly known as red roundworm, brown roundworm, kangpanworm, yagus and blowing silkworm.
Male mesenchymals are winged mesozoans that are very good at flying, and in general, the harm to fruit trees is not very large; while female mesozoans have no wings, and once their larvae are feathered, they will live on the branches or fruits of fruit trees for life, thus bringing continuous major harm to fruit trees. Fruit trees that breed mesozoans have yellowing leaves, wilted branches, declined trees, and often suffer from coal pollution.
The insect body of the insect has a hard shell, covered with wax powder, and the resistance to drugs is very strong, and it is difficult for general agents to enter its body, and it is very difficult to control. Therefore, once a worm appears on a fruit tree, it is very difficult to remove it.
However, with the development of science and technology, Bayer AG, headquartered in Leverkusen, Germany, has successfully developed an insecticide known as "tick buster", spirant ethyl ester, which has a better effect on killing ticks.
Bayer AG is one of the world's most well-known Fortune 500 companies. With 750 production plants in 200 locations on six continents, the company employs a total of 120,000 people and 350 branches in almost all countries of the world, making it the largest industrial group in Germany. Founded in 1863, the company produced aspirin, known as the "Medicine of the Century," in 1899, and since then, the company has become famous all over the world.
According to the data, the new insecticide ethyl spirant produced by Bayer is a quaternary ketoacid compound and is one of the modern insecticides with bidirectional internal absorption conductivity. Once the insecticide enters the plant, it can move freely in the plant, so that the whole body of the plant (including the leaves) is covered with the medicinal solution, which in turn makes the stinging plant pests escape the doom of being poisoned. At the same time, because the medicinal effect of ethyl spirant ester can be up to 8 weeks, sprayed once, can kill all the eggs and larvae of pests, therefore, spirant ethyl ester is also known as a "long-acting insecticide".
In addition, ethyl spirant, also known as a "broad-spectrum high-efficiency insecticide", can not only kill aphids, but also kill aphids, thrips, psyllids and other stinging mouth organ pests, can be widely used in fruit trees, cotton, soybeans, hops, potatoes and vegetables and other insecticidal needs.
In general, when controlling citrus tree mesophyllum, 240 g/l of heliosper ethyl ester 4000-5000 times liquid can be used for spraying, and the effect of killing insect shell insects can reach about 95%. In order to enhance the killing effect of ethyl spirophyllate on the insect shell insects, some growers will use the combination of ethyl spirode + avermectin to kill the insect shell insects, which can increase the effect of killing the insect shell insects to 98%.
According to the fruit farmers who have used the compound method to kill the insect shell insects, they use 20% avermectin + 240 g/l spironium ethyl ester 3500 times liquid to make avi from mid-May to mid-June every year. Spirochetes ethyl ester suspension sprayed on the whole plant of citrus trees, the control effect after 18 days can reach 98.73%, the control effect is quite good, at the same time, this compound preparation can also treat red spiders, leafhoppers, heartworms and other pests. Interested growers may wish to give it a try.
