In 2015, global acaricide sales were $773 million, accounting for 4.6% of the $18.74 billion pesticide market and 1.3% of global pesticide sales of $57.532 billion.
The main uses of acaricides include cotton, fruit trees and vegetables, especially citrus and grapes. The market for acaricides used in fruit trees in developing countries is increasing year by year.
It is widely used in China and plays an important role in the prevention and control of agricultural pest mites. However, due to the single use for many years without rotating with other acaricides, coupled with the listing of a large number of pyridine-containing mixtures, it has made pest mites in some areas resistant and should be of great concern. For this reason, it is best to use this agent only once a year and rotate with other acaricides.
Pyridoxine has been very stable in the sales of acaricides in the top few products, the following for everyone to introduce the specific situation of pyridoxine products.
Varieties of pesticide acaricides
The sales volume of acaricide products are spironyl ester, butyl etherurea, spironyl mite, alkyne mite, biphenyl hydrazide, pyridoxine, thiophenone and avermectin. With global sales of around $45 million, pyridoxine is also a good variety of acaricides.
Basic information about the pyridoxine
Mechanism of action of pyridine
Pyridoxine is a pyridazone insecticide, acaricide, it is very strong contact killing, but has no fumigation, internal absorption and conduction effects. It mainly inhibits the synthesis of glutamate dehydrogenase in muscle tissue, neural tissue and electron transport system chromosome I, thereby exerting insecticidal and mite-killing effects.
Characteristics of Pyridoxine
Pyridoxine is a broad-spectrum, tactile acaricide that can be used to control a variety of plant-eating pest mites. It has a good effect on the entire growth period of mites, namely eggs, young mites, nymphs and adult mites, and also has obvious rapid killing effects on adult mites during the mobile period. The drug is not affected by temperature changes, whether used in early spring or autumn, satisfactory results can be achieved.
Application of pyridoxine
Efficient, broad-spectrum acaricide, no systemicity, for leaf mites, full claw mites, small claw mites and other edible plant pest mites have obvious control effects, and for eggs, mites, adult mites are effective, and also effective for the movement period of adult mites.
Suitable for citrus, apples, pears, hawthorns, cotton, tobacco, vegetables (except eggplant) and ornamental plants.
If it is used for the control of rust ticks such as citrus and apple red spiders, pears and hawthorns, it can be applied during the occurrence of pest mites (in order to improve the control effect, it is best to use at an average of 2 to 3 heads per leaf), and 20% wettable powder or 15% emulsion is diluted to 50 to 70mg/L (2300 to 3000 times) spray.
The pyridoxin has a good knockdown effect on jumping armor, and the amount of 30g per mu can kill jumping armor in 10 minutes.
Tips for using the mite
It can be used to control multi-planted food pest mites, and has a good effect on the control of prickly pests such as nymphs, whitefly nymphs, planthoppers, thrips and aphids.
✔ Spray with 15% emulsion:
(1) Use 1500 times the liquid to prevent and control Shenze leaf mites, Turkestan leaf mites, bean leaf mites, and six-spotted leaf mites on beans.
(2) Use 2500 times the liquid to control truncated leaf mites.
(3) With 3000 times the liquid, prevent and control side multi-food tarsal mite (tea yellow mite)
Spray with 20% wettable powder: use 1500 to 2000 times liquid to control leaf mites and tarsal mites on vegetables, and can also treat pests such as aphids, whiteflies, and thrips.
✔ Mixing works well
At present, through the specific situation reaction of farmers in various provinces using dale mite, it is generally now mixed with dammer. Avida mite, dapyridine spironyl ester, pyridoxine also with furazine, acetamidine, methyl vitamin salt, cypermethrin, thiazide, butyl etherurea, tetramuthone and other compounds, can effectively improve the control effect, increase the control spectrum, while reducing the dosage of other agents.
✔ Advantages of pyridine:
The amount of pyridoxin is small, the initial effect is good, the efficacy is long, it is less affected by temperature and insect state, and it is widely used in fruit trees, vegetables, tea trees, tobacco and flowers.
Precautions for pyridoxine
Notes:
(1) Crops can be used up to 3 times per season, with a safety interval of 21 days.
(2) Can not be mixed with stone sulfur compound and Bordeaux liquid and other strong alkaline agents.
(3) Do not pollute wells, ponds and water sources, and it is forbidden to clean the application apparatus in rivers and ponds and other water bodies.
(4) It is toxic to bees and silkworms, and the influence on the surrounding bee colonies should be avoided during the application of the drug, and it is forbidden near the flowering period of flowering plants, jamsils and mulberry gardens. Red-eyed bees and other predators are disabled in the release area.
(5) Pregnant and lactating women should avoid contact with the drug.
Please pay attention to the three views of agriculture, share more plant protection technology, so that agricultural harvest, let the countryside beautiful, let farmers increase income.
