Can agricultural silicones cause phytotoxicity? The main points of use of agricultural silicone
Pesticide silicone is a kind of pesticide additive commonly used by agricultural people because it can achieve the effect of enhancing the effect. However, in daily use, many people add silicone whether they are sterilizing or killing insects or weeding. Here Xiaobian will tell you: In fact, silicone also has its use requirements, you must not add it!
What is the right thing to add silicone?
The utility of silicone can help pesticides reduce surface tension and enhance the wetting and adhesion of pesticides on the surface of plants. It can also be understood that it can improve the adhesion and penetration of the liquid; for some crops with thicker waxy layers, it can help the pesticides to exert their effects. So, here is a question: Do we need to add silicone when we are configuring pesticides? Can you add silicone? Here we need to know that if we are in a high temperature environment when using the drug, or the wax itself is thinner, it is not suitable for adding silicone; it may cause phytotoxicity. The principle is that silicone can cause the decomposition of the stratum corneum of the epidermal cells of the leaves; if the wax layer is thicker, it does not matter, but if it is used on a thinner waxy layer, the water retention capacity of the plant will decrease, the cells will be damaged, and then appear. Drug damage. Another reason is that if some permeable fungicides are added to silicone, it will easily lead to excessive violent effects; at the same time, the contact herbicides are similar.
Can the concentration of silicone be increased?
After confirming that silicone can be added, it is necessary to consider the concentration problem. In the case of adding silicone, the effect is already very strong; at this time, if the concentration of the drug is increased at will, it is inevitable that phytotoxicity will occur. At the same time, when the pesticide is added, if the silicone is added to our pesticides, the speed of the drug should be appropriately accelerated. If it is slowly taken, the plants under the unit area will be exposed to too much medicine, resulting in the occurrence of phytotoxicity.
Under normal circumstances, do not add silicone to the emulsifiable concentrate, the emulsifiable oil itself is relatively strong, such as avermectin. In the fungicide, azoxystrobin, ether oxystrobin, pyraclostrobin, the permeability is relatively strong, can not add silicone, selective herbicides generally do not add silicone, crop resistance to selective herbicides , also limited, wild herbicides (glyphosate, glufosinate), plus better!
