With the advent of autumn, piercing-sucking pests such as aphids, thrips, and planthoppers have entered the peak period of occurrence. These pests have the characteristics of fast reproduction, easy outbreaks, and strong drug resistance, and the update rate of pesticides is very fast. Today, the editor recommends a new pesticide for controlling piercing-sucking pests – flonicamid, which is a new type of pesticide launched after imidacloprid, acetamiprid and pymetrozine.
1.Insecticidal mechanism
Flonicamid is a novel low-toxicity pyridylamide insect growth regulator insecticide. After aphids and other piercing-sucking pests eat and inhale the plant sap with flonicamid, they are prevented from sucking the sap after a few minutes, the needle cannot be inserted into the plant tissue, and no excrement appears within 1 hour,Then die.
2.Main features
Flonicamid is a new type of pyridine amide insecticide. In addition to contact and stomach toxicity, it also has good nerve agent action, good penetration and rapid antifeeding action. It can quickly penetrate into stems and leaves through root absorption, and play a positive and negative role; after pests ingest the pesticide, they are quickly prevented from sucking juice and quickly stop sucking, so that the oral needle tissue of sucking pests such as aphids cannot be inserted. plant tissue to death. In addition, flonicamid has no cross-resistance with imidacloprid, acetamiprid, pymetrozine and other drugs widely used in production at present, and the insecticidal effect is very good.
3.Applicable crops
Flonicamid can be used in apples, pears, peaches, plums, strawberries, cucumbers, melons, watermelons, gourds, kale, tomatoes, eggplants, peppers, potatoes, mustard greens, spinach, lettuce, beans, celery, wheat, corn, cotton , citrus, sunflower, tea, ornamental plants and other crops.
4.Target
Mainly used to control all kinds of aphids, greenhouse whitefly, Bemisia tabaci, green leafhopper, brown planthopper, all kinds of thrips and other pests.
5.Usage Method
(1) To control all kinds of aphids, in the early stage of occurrence, 30-50 grams of 10% flonicamid water-dispersible granules per mu, mixed with 30-50 kg of water, can be sprayed evenly. In order to achieve the ideal control effect, It can be sprayed again after 7 days to effectively control the continued damage and spread of aphids. You can also use 50% fluorine and pymetrozine water dispersible granules at 15 to 20 g/mu, spray after mixing with water, and the quick effect is better.
(2) For the control of rice planthopper and brown planthopper, it can be used in the peak period of the young nymphs of rice planthopper, and 70-90 grams of 53% fluridine·isoprocarb wettable powder is used per mu, mixed with water and sprayed, focusing on the The middle and lower parts of the rice and the front and back of the leaves are evenly and thoroughly sprayed. The prevention effect is more prominent.
(3) For the control of thrips, spray at the initial stage of the young nymphs of the pest. After 4:00 pm, use 7-8 grams of 50% fluorine acetamiprid water dispersible granules per mu each time, add 30 kg of water to spray , can quickly control the spread of thrips.
