Insecticide Chlorophyphos Chlorpyrifos Dursban 480g/L Ec 10%Gr Pesticide Use in Agriculture

Chlorpyrifos is a neurotoxic agent that primarily targets the nervous system of pests. Once the chemical enters the insect's body, it inhibits the activity of acetylcholinesterase, disrupting the normal conduction of nerve impulses and leading to the death of the pest. It has multiple modes of action, including contact, stomach, and fumigation, but it does not have a systemic effect. Chlorpyrifos acts quickly and has a long residual period; while its residue duration on crop leaves is relatively short, it remains in the soil for a longer time. Therefore, it is particularly effective in controlling underground pests, with a residual efficacy that can last over 30 days.

Application

Three Main Methods of Controlling Pests with Chlorpyrifos:
1. Spraying: Dilute 48% chlorpyrifos emulsion in water for spraying.
1.1 Use a dilution of 800-1000 times to control the larvae of Liriomyza sativae, Liriomyza tomatensis, Liriomyza huidobrensis, and Empoasca fabae.
1.2 Use a dilution of 1000 times to control the larvae of Plutella xylostella, Spodoptera litura, Helicoverpa armigera, and Tuta absoluta as well as aquatic vegetable pests.
1.3 Use a dilution of 1500 times to control the pupating larvae of Liriomyza chinensis and Tuta absoluta.

2. Root Drenching: Dilute 48% chlorpyrifos emulsion in water for root drenching.
2.1 During the initial peak of Allium tuberosum maggot egg-laying, use a dilution of 2000 times to control the maggot, applying 500 liters of solution per acre.
2.2 In early to mid-April, when drenching garlic for the first or second time, use 250-375 milliliters of emulsion per acre mixed with water to control root maggots.
2.3 Use a dilution of 2000 times to drench the roots of the plants for controlling earthworm damage, applying 250-300 liters of solution per acre.

3. Soil Treatment: Apply 2-4 kilograms of 3% chlorpyrifos granules per acre, before sowing or transplanting, using either furrow application, hole application, or broadcasting to control Allium tuberosum maggots, grubs, and cutworms.
