Thrips use nymphs and adults to file and suck the flowers, leaves, buds and young fruits of mangoes, which seriously affect the growth and fruit quality of mangoes. In recent years, in mango production, thrips have risen from a secondary pest to a major pest due to the misuse of pesticides.
In large-scale mango-growing areas such as Sanya and Guangxi in Hainan, growers often feel headaches about the prevention and control of thrips. Because thrips are active in mango trees all year round, especially in Hainan, 10 to 12 generations a year, overlapping generations, and coexisting insect states make it more difficult to control the work.
Jingbo agricultural technology experts remind all growers: prevention and control of thrips, prevention first, comprehensive prevention
Every day, we must do a good job in mango orchard cultivation management, fertilizer and water management, etc., to promote the growth of plants and reduce the harm; we can also protect and use natural enemies, such as blunt mites, spiders and predatory tsubaki elephants. In addition to the necessary precautions, it is also important to choose the right medicine for prevention and control, and it is recommended to use the Kyobo Swordsman, Kyobo Dukadi to control thrips. Let's take a look at their excellent results in controlling mango thistle horses.
Experiment 1 uses recipe: Kyobo Swordsman 15ml, randomly selected 3 mango trees in the orchard.
Technicians returned to the test an hour later, and the thrips fell to the old leaves after death, with obvious effects and high mortality.
Experiment 2 Using Formula: Kymbeau Ducadi 5ml + Gimboli Bud 15g
The technician then observed the situation of the dead insects: after 30 minutes, the dead insect rate was about 45%, and the quick-activity became significantly higher after adding Jingboli buds.
Summary of prevention and control experience and technology:
Because the thrips are small, the activity is hidden, often hiding in the flower organs or the formation of insects, so the harm is not easy to be detected by people at the beginning, often after causing serious disasters, so it is necessary to strengthen daily management, once the thrips hazard is found, it should be used immediately; when the insect mouth base is large, it is necessary to increase the amount of medicine or add imidacloprid, acetamiprid, thiamethoxine and other insecticides to ensure that the insecticide is more thorough, and the compound use of the two insecticides is more conducive to preventing thrips and other pests from becoming resistant to the agent.
