In traditional pesticide spraying, only 20 to 30% of the pesticide solution can be stored on the leaves of crops, and 70 to 80% of the pesticide is lost to the soil and atmospheric environment, which not only increases pesticide residues, but also pollutes the environment and wastes water. resource. Therefore, scientists are trying to find a more efficient auxiliary that can make more pesticides stay on the leaves and spread them quickly. Then, with only a small amount of spray, the pesticides can be exposed more quickly and effectively. Invading enemies. After unremitting efforts and experiments, scientists finally developed agricultural silicone additives. Agricultural silicone additives have the following effects:

1. Quickly moisten crops and greatly improve drug efficacy

The details can be reflected from the following examples: Rice leaf roller is a rice pest. In order to escape the pesticide spray, this guy worked tirelessly to spin out silk threads and carefully weave a safe fortress for itself. The silk threads are like buttons, closing and rolling the leaves, and the rice leaf roller hides in this fortress. Then, he sucked the juice from the leaves from the inside out. Unexpectedly, with such good intentions, he was easily taken down by the all-pervasive magical silicone additive. The liquid spread rapidly, penetrated into the cracks and entered the fortress, feeding the rice. The leaf-roller moth comes to catch turtles in an urn.

In the field, 48% dichlorpyrifos EC is used to prevent rice leaf rollers, and the water consumption per acre is more than 45 kilograms. By adding 0.05% silicone additive to the liquid, the ideal insecticidal effect and liquid retention effect can be achieved with only 15 kilograms of water per acre. In this way, both water resources and workload are saved.

Therefore, farmer friends must remember that after adding silicone additives, there is no need to spray repeatedly as in the past, otherwise it will be counterproductive and a waste of manpower and material resources.

2. Super penetration, allowing the drug to quickly reach the target.

In nature, many plant leaves have a thick layer of wax, which makes it difficult for medicinal solutions to adhere to them. The special structure of some leaves, such as lotus leaves, taro leaves, etc., makes it almost difficult for water to stay. Pests often go to great lengths to avoid being hunted. Look, this cabbage is not damaged on the surface, but when you break open the leaves, you can see that the inside has been badly eaten by diamondback moths. The cunning diamondback moth gnaws at the vegetable leaves, but it does not bite through them, but leaves a thin layer of skin, like a safe umbrella, protecting them underneath. So, is there any trick for silicone to deal with the waxy layer on leaves? Something gratifying happened again. There are no water droplets formed on the leaves. The super spreadability of silicone allows the liquid to spread freely even on waxy leaves. Look, none of the diamondback moths that were eating the leaves survived.

Field experiments have shown that adding 0.03% to 0.05% (2000 to 3000 times) of silicone additives to pesticides for controlling diamondback moth can not only reduce the amount of spray but also appropriately reduce the amount of pesticides when the control effect is equivalent. This effectively reduces pesticide residues in vegetables. Silicone additives can also promote the rapid absorption of pesticides through the pores on plant leaves. We used water to simulate rainwater flushing. On the left, the chemical solution with silicone additives added has partially entered the leaves, while on the right, the ordinary chemical solution that failed to enter the leaves was quickly washed away. It has been found that the addition of silicone additives can improve the reliability of the use of systemic agents. During the rainy season, reduce losses caused by repeated spraying. The permeability of silicone can also be used to deal with pests that have a waxy layer that is not easily wetted by the chemical solution.

In fact, the role of silicone goes far beyond that. It can be used as an efficient auxiliary and is widely used in agricultural applications such as pesticides, fungicides, herbicides, foliar fertilizers, plant growth regulators, trace elements and biopesticides. Chemical spray. It achieves the purpose of increasing efficiency, saving water, saving labor and pesticides, reducing pesticide loss and reducing pesticide residues.
