Spirotetramat is a new type of tetronic acid derivative insecticide that can cause larval death and reduce the reproductive capacity of adults by interfering with the fat biosynthesis of insects. So, what are the insecticidal characteristics of spirotetramat? How is the compounding effect of spirotetramat? What precautions should be taken when using the drug? Today, let's talk about spirotetramat in detail.
1. What are the insecticidal characteristics of spirotetramat?
(1) Bidirectional systemic conduction, thorough insecticide
Bidirectional conduction means that the drug solution can move upward and downward throughout the body of the crop and can reach difficult-to-reach parts. As one of the modern insecticides with bidirectional systemic conduction, spirotetramat can be bidirectionally systemic in the xylem and phloem. The drug solution moves upward and downward to the leaves and bark of the crop, thereby controlling pests hidden on the inner leaves of lettuce and cabbage, as well as on the bark of fruit trees.
(2) Broad spectrum of insecticides
Spirotetramat can be used on a variety of crops such as citrus, grapes, cucumbers, peppers, eggplants, onions, watermelons, cotton, soybeans, potatoes, etc. It has a good preventive effect on pests such as scale insects, red spider mites, aphids (apple cotton aphid, citrus aphid, peach aphid, root nodule aphid), psyllids, pear psyllids, whiteflies, thrips (flower thrips, tobacco thrips, tea yellow thrips), etc., especially for pests that are not easy to be found and have shells (such as scale insects and whiteflies).
(3) Long lasting effect
Spirotetramat can control the second generation of pests with a single application and can provide effective prevention and control for up to 8 weeks, with a relatively long lasting effect!
(4) Spirotetramat is generally toxic to adult insects, but it can affect their egg laying. Even if they are laid, the eggs cannot develop normally.
2. Spirotetramat compound pesticides
Spirotetramat is a bidirectional systemic insecticide that kills insects thoroughly, but the killing speed is relatively slow. Sometimes it needs to be mixed with other pesticides to increase the killing speed.
(1) Spirotetramat·Dinotefuran
It has triple effects of contact, stomach poison and systemic. After application, it can be transmitted bidirectionally in the crop body, which can not only kill insects comprehensively, but also protect new leaves and fruits. It can effectively control: citrus tree scale insects, aphids, psyllids, pear tree psyllids, tomato whiteflies, cucumber whiteflies, pepper whiteflies, tea tea leafhoppers, apple tree aphids, peach tree aphids and other pests.
(2) Spirotetramat·Thiacloprid
It has a long lasting effect and is more effective against piercing-sucking pests! It can control: cucumber, tomato, pepper whitefly larvae and aphids.
(3) Abamectin + Spirotetramat: can effectively control whiteflies, aphids, and thrips
(4) Spirotetramat·Chlorpyrifos
It has contact, stomach poison and strong systemicity, and is transmitted up and down in the crop body. It can effectively resist scale insects.
3. What are the precautions for using Spirotetramat?
Spirotetramat is one of the modern insecticides with bidirectional systemic transmission performance. It controls various piercing-sucking mouthparts pests, such as aphids, thrips, psyllids, mealybugs, whiteflies and scale insects. So, what are the precautions for using Spirotetramat?
Precautions for using Spirotetramat:
(1) In order to avoid and delay the development of resistance, it is recommended to rotate with other insecticides with different mechanisms of action, and at the same time ensure that there are no adverse effects.
(2) When preparing and applying the product, you should still wear protective clothing, gloves, and masks; smoking and eating are strictly prohibited.
(3) Avoid accidental ingestion or splashing on the skin, eyes, etc.
(4) After application, wash hands, face and other exposed parts of the body and clothing contaminated by the drug with soap and plenty of water.
(5) Empty packaging should be washed three times and properly disposed of after smashing or scratching. Do not reuse.
(6) It is prohibited to use near aquaculture areas, rivers and ponds, and it is prohibited to wash the application equipment in rivers and ponds.
(7) It is prohibited to use during the flowering period of flowering plants and in mulberry gardens and silkworm rooms.
(8) Pregnant and breastfeeding women should avoid contact.
(9) The safe interval of spirotetramat on citrus and tomatoes is 5 days and 40 days respectively. It can be applied to tomatoes or citrus at most once per season.
(10) Spirotetramat is a systemic insecticide with stomach poisoning as the main effect and contact killing as the auxiliary effect. When applying, the crop leaves, tree trunks, branches, etc. should be fully covered with the drug.
