Propargite is a highly efficient and low-toxicity organophosphorus broad-spectrum acaricide with no systemic absorption and low residue. It has both contact and stomach toxicity effects. Its structural type belongs to IRAC 12C and acts as an inhibitor of insect mitochondrial ATPase, leading to the interruption of normal respiratory metabolism in mites, resulting in their death. It can eliminate harmful mites on various crops such as cotton, vegetables, fruit trees, corn, and flowers, effectively controlling mite reproduction while being harmless to natural enemies and showing no resistance.
Bifenthrin, a synthetic pyrethroid insecticide, has contact and stomach poisoning effects. It lacks systemic or fumigant properties. Highly effective against pests, it offers a wide range of action. The product leaves low residue and requires a small amount for application. Additionally, it can control mites. Rapid development occurred in the 1970s and 1980s, leading to its widespread use around the world. Today, it remains a popular choice among insecticides.
Features of Propargite
1. A low-toxicity broad-spectrum organosulfur acaricide with three modes of action: stomach toxicity, contact killing, and fumigation, but without systemic absorption or penetrative conduction. It is effective against adult mites, nymphs, larvae, and mite eggs, showing special efficacy against mite species resistant to organophosphates and fenpyroximate.
2. Its effectiveness is particularly notable during high-temperature seasons when mites are difficult to control.
3. The mechanism of action is unique, characterized by high efficacy, quick action, and a lasting effect of over 25 days.
4. It is relatively safe for bees and natural enemies, has a long residual effect, low toxicity, and minimal harm to humans, livestock, and the natural environment, making it an ideal acaricide for integrated pest management.
5. Propargite is often mixed with components such as abamectin, bifenthrin, fenpropathrin, pyridaben, hexythiazox, fenpyroximate, mineral oil, and die-sel to produce combination acaricides.
Features of Bifenthrin
1. Broad insecticidal spectrum and wide range of applicable crops. Bifenthrin is effective against various pests, including those from the Lepidoptera, Hemiptera, Coleoptera, and Thysanoptera orders. It also has some efficacy against mite pests. It can be used on field crops such as wheat, corn, peanuts, soybeans, and rice, as well as on fruit trees like citrus, apples, grapes, and bananas. Additionally, it is suitable for vegetable crops such as cabbage, leeks, tomatoes, peppers, and eggplants, as well as economic crops like watermelon and cotton, and tea gardens. It controls various pests, including aphids, cotton bollworms, pink bollworms, tea geometrids, tea caterpillars, tea leafhoppers, fruit tree borers, citrus leaf miners, diamondback moths, and cabbage loopers. It can also be used to manage underground pests like leek maggots, garlic maggots, grubs, golden needle bugs, cutworms, and mole crickets, and can control mites as well.
2. Fast insecticidal action and high safety. Bifenthrin primarily works through contact and stomach poisoning. Compared to other pyrethroid insecticides, it has a higher insecticidal activity. After spraying the solution, pests begin to die within one hour, with peak mortality reached within four hours, allowing for rapid elimination of pests. Furthermore, bifenthrin does not move in the soil, making it relatively safe for the environment, and it is less likely to cause phytotoxicity due to factors like temperature or improper application concentration.
3. Simultaneous control of insects and mites with a long residual period. The residual effectiveness of bifenthrin can last up to 10-15 days. However, it is important to note that its efficacy against mites can be unstable and may lead to resistance, so it is not recommended for use as a dedicated acaricide.
Application of Propargite
1. Citrus: Before flowering, spray a 1500-2000 times dilution of 73% Propargite emulsion. After flowering, spray a 3000-3500 times dilution of 73% Propargite emulsion to control citrus red mites, leaf-eating mites, and six-spotted leaf-eating mites. In early June to September, when rust mites appear, use a 2500-3000 times dilution of 73% Propargite emulsion.
2. Lychee: In December of the current year and January of the following year, spray a 800 times dilution of 73% Propargite emulsion once each month to control lychee gall mites.
3. Loquat: In March to April, during the peak period of tick infestation, spray a 800 times dilution of 73% Propargite emulsion on the canopy of loquat trees.
4. Apple: During the peak period of full-claw mites and hawthorn nymphs, spray a 1500-2000 times dilution of 73% Propargite emulsion.
5. Tea garden: Before the peak occurrence of tea red spider mites, tea orange gall mites, and tea leaf gall mites, use 30-40 ml of 73%Propargite emulsion diluted in 50-75 kg of water per mu for spraying.
6. Mulberry: During the peak occurrence of red spider mites, spray a 2500-4000 times dilution of 73% Propargite emulsion.
7. Cotton: During the peak occurrence of red spider mites, use 30-45 ml of 73% Propargite emulsion diluted in 60-75 kg of water per mu for spraying; if the cotton is in the seedling stage (seedling height less than 25 cm), the solution should be diluted more than 2500 times.
8. Corn: When leaf mites occur, spray a 1500-2000 times dilution of 73% Propargite emulsion.
9. Solanaceous vegetables, legumes, and melons: At the initial outbreak of red spider mites and nymphs, use 23-40 ml of 73% Propargite emulsion diluted in 75-100 kg of water per mu for spraying; if in the seedling stage (seedling height less than 25 cm), the solution should be diluted more than 2300 times.
10. Soybeans and peanuts: When leaf mites occur, spray a 1500-2000 times dilution of 73% Propargite emulsion.
