Red spider mite, whose scientific name is spider mite, has the characteristics of strong fecundity, many generations, and a wide mode of transmission.
Once it occurs, it will cause yellow leaves, scorched leaves, rolled leaves, fallen leaves, and even cause the leaves to die. It is a harmful mite.
Every March-May and September-October will usher in the outbreak period, especially after entering April, under the nourishment of suitable temperatures and rich young leaves, the number of red spiders can expand rapidly.
Spider mites can cause significant damage to plants, crops, and trees, which can be costly to farmers and gardeners. The red spider mite is not an insect, and the control effect cannot be achieved by using ordinary insecticides, and it may also kill natural enemies by mistake. In order to achieve the ideal control effect, it is necessary to select the appropriate acaricide.
Among the many acaricides, dextate can be said to be unique. It is popular with growers worldwide due to its ability to control spider mite populations and its residual activity after application.
Red spiders are prone to drug resistance, but after the successful development of Propargite in 1968 by the Uniroyal Company of the United States, it has been used to control red spiders for decades, and no drug resistance has been found so far.
In addition, decantate is also selective, safe for bees and natural enemies, and less harmful to humans, animals, and the natural environment. Overall, it is an ideal acaricide with high efficiency and low toxicity.
In this blog, we’ll discuss the benefits and proper use of prodiclofen to help you fight spider mites.

How does Propargite work?
Propargite is a broad-spectrum insecticide that belongs to organosulfur insecticides. It is a mitochondrial ATPase inhibitor, which destroys the normal metabolism of mites through contact killing and stomach poisoning, so as to achieve the purpose of killing mites.
Immediately after exposure to clofenac, the mites stopped eating, laid fewer eggs, and generally died within 48 to 96 hours. Caprodite is commonly used, non-dripping, selective and environmentally friendly.
Propargite is a member of the organosulfur compound family and works well against mites that have become resistant to other insecticides. It is a contact insecticide, which means it must come into direct contact with the mites to be effective. Acetate comes in the form of a spray or powder, and it absorbs quickly through the cuticle of the mite’s body.
The effectiveness of propidate as an insecticide depends on a variety of factors, including the timing and frequency of application, the rate and method of application, and the presence of other insecticides or chemicals that may interfere with its activity.
As with any pesticide, proper safety procedures and regulatory guidelines must be followed when using decantate to avoid any adverse effects on human health or the environment.
What is the advantage of Propargite?
Works well at high temperatures. When the temperature is lower than 20°C, the drug effect gradually weakens. When the temperature is higher than 27°C, it has dual functions of touching and fumigation. In hot and humid weather, spraying high concentration of citrus shoots and young fruit may cause phytotoxicity (leaf wrinkling or spotting), but has no effect on crop growth.
Low residue. In most fruits, Propargite remain mainly on the surface of the plant, and as the leaves peel off, their content decreases, and only trace residues are found in the flesh.
No absorption and osmotic conduction. It is safe for crop growth and should be thoroughly sprayed on both sides of the leaves and the surface of the fruit when used.
Low toxicity. In China,231 of the 259 registration certificates contain low-toxicity products.
Long duration (15-25 days). The safe interval for use on citrus trees is 30 days, up to 3 times per season.
The control effect on adult mites and mites is better, but the effect of killing eggs is poor. For eggs, you can choose another product- Hexythiazox.
How can you find Propargite with good quality and low price?
If you want to guarantee the quality and price of Propargite, it is important to choose a manufacturer rather than a trading company. We recommend looking for manufacturers with proven formulations such as Heben which offer Propargite 57% EC, Propargite 73% EC, and more!
