HR-8039 Agricultural Silicone Spreading Agent

       Agricultural silicone spreading agent HR-8039 is a modified polysiloxane, silicone surfactant with high-efficiency spreading ability. Agricultural silicone spreading agent HR-8039 can reduce the surface tension of water to 20.5mN/m at a concentration of 0.1% (wt.). After mixing with a pesticide solution in a certain proportion, it can reduce the contact angle between the spray liquid and the leaf surface. Therefore, the coverage of the spray is increased, and the agricultural silicone spreading agent HR-8039 can make the pesticide absorbed through the stomata of the leaves, which is very effective for improving the efficacy, reducing the amount of pesticides, saving costs, and reducing the pollution of pesticides to the environment. of.

The Features:

        Agricultural silicone spreader HR-8039 has high-efficiency spreading and permeability, good systemic absorption, conductivity, and rain erosion resistance.

The Product index:

Range of use:

        Agricultural silicone spreading agent HR-8039 can be added to the spray mixture of biological pesticides such as insecticides, fungicides, herbicides, foliar fertilizers, and plant growth regulators, and is very suitable for systemic pesticides.

The Instructions:

       1. Use tank-mixed spray, Usually add 5 grams of agricultural silicone spreading agent HR-8039 (4000 times) to every 20 kg of spray liquid, mix well and use immediately. If it is necessary to promote the absorption of systemic pesticides, further improve the efficacy of pesticides or reduce the amount of spraying, the dosage of agricultural silicone spreading agent HR-8039 should be increased appropriately. Generally, the dosage of plant growth regulator is 0.025%-0.05%, the dosage of herbicide is 0.025%-0.15%, the dosage of insecticide is 0.025%-0.1%, the dosage of fungicide can be 0.015%-0.05%, the dosage of fertilizer and trace elements 0.015-0.1%.

When using, first dissolve the pesticide, add 80% water and mix well, then add agricultural silicone spreading agent HR-8039, then add 100% water and mix well. It is recommended that when using the agricultural silicone spreading agent HR-8039, the water consumption should be reduced to 1/2 (recommended) or 2/3 of the conventional dosage, the dosage per unit area can be reduced to 70-80% of the conventional dosage, and a smaller pore size should be used Nozzles, the spray speed is appropriately accelerated.

       2. Use of pesticide stock solution, When added to the pesticide stock solution, it is recommended to add 0.5-8% of the pesticide stock solution. Adjust the pH value of the pesticide formulation to 6-8. Users should adjust the amount of agricultural silicone spreading agent HR-8039 according to different pesticide varieties and formulations to achieve a very economical and effective effect. Compatibility tests and step tests should be done before use.

The Packaging and storage:

Packed in 25kg and 200kg plastic barrels, stored in a cool place, protected from direct sunlight, with a shelf life of 2 years, and transported as non-dangerous goods.
