The traditional pesticide spray, only 20~30% of the liquid can be stored on the leaves of crops, 70~80% pesticides are all lost. Agricultural organosilicon is a more efficient additive, which can make more liquid medicine stay on the leaves and develop rapidly.
But,
Why do some people use silicone to save money and effort, while some people use silicone to produce drug harm?
Is agricultural organosilicon additive omnipotent? How to use organosilicon? How to match? What are the precautions for use?
Comparison of the ductility of liquid medicine before and after adding organosilicon
1. Quickly moisten crops, greatly improve efficacy
It can be embodied in the following examples: rice leaf roller is a kind of rice pest. In order to escape the pesticide spray, the guy worked hard to spit silk thread and weave a safety fortress for himself. Like a button, the silk thread closes and rolls up the leaves, and the rice leaf roller hides in this fortress. Then, from the inside to the outside, I sucked in the juice of the leaves. Unexpectedly, it was so painstaking, but it was easily taken down by the all-in-one magic organic silicon assistant. The liquid medicine spread rapidly, penetrated into the gap into the fortress, and caught the turtle in a jar for the rice leaf roller.
In the field, 48% chlorpyrifos EC was used to prevent rice leaf roller. The water consumption per mu was more than 45 kg. Adding 0.05% organosilicon additive into the liquid medicine, only 15 kg water consumption per mu can achieve the ideal insecticidal effect and liquid retention effect. In this way, water resources and workload are saved.
So, farmer friends must remember that after adding silicone auxiliaries, spray does not need to be sprayed repeatedly as before, otherwise it will backfire and waste manpower and material resources.
2. Super penetration, make the medicine reach the target quickly.
In nature, there is a thick layer of wax on the leaves of many plants, and it is difficult for the liquid medicine to attach to it. The special structure of some leaves, such as lotus leaf and taro, hardly make water stay. In order to avoid killing, pests always try their best. Look, there is no damage on the surface of this cabbage, but when you open the leaves, they have been eaten badly by the Plutella xylostella. The cunning diamondback moth gnawed at the leaves of the vegetable, but it did not bite it through, but left a thin skin, like a safety umbrella, to protect them below. So, silicone against the wax layer on the leaves, there is no magic trick? The good news is back. There is no water drop on the leaves. The super unfolding performance of organosilicon makes the liquid medicine expand freely on the waxy leaves. Look, none of these diamondback moths that are eating leaves survived.
Field experiments showed that adding 0.03% to 0.05% (2000~3000 times) of organosilicon auxiliaries in the control of diamondback moth could reduce the amount of spray and reduce the dosage of pesticides. Thus, the pesticide residues in vegetables are effectively reduced. Organosilicon additives can also promote the rapid absorption of pesticides through the stomata on the leaves of plants. We use water to simulate the rain wash. The liquid medicine added with organosilicon additives on the left has partially entered the leaves, while the ordinary liquid medicine that failed to enter the leaves on the right has been washed away quickly. It has been found that the addition of organosilicon additive can improve the reliability of the internal absorption agent. In the rainy season, reduce the loss caused by repeated spray. This permeability of organosilicon can also be used to deal with those pests with waxy layer that are not easy to be wetted by liquid medicine.
In fact, the role of organosilicon is far from being used. It can be used as an efficient assistant for spraying pesticides, fungicides, herbicides, foliar fertilizers, plant growth regulators, trace elements and biological pesticides. To achieve the purpose of efficiency, water saving, labor and medicine saving, reducing pesticide loss and pesticide residue.
What kind of ratio should be used for such magic organosilicon additives? Here, we would like to ask you to remember the following set of numbers:
Insecticide 0.025-0.1% (1000-4000 times)
Bactericide 0.015-0.05% (2000-7000 times)
Herbicide 0.025-0.15% (700-4000 times)
Plant growth regulator 0.025-0.05% (2000-4000 times)
Fertilizer and microelement 0.015-0.1% (1000-7000 times)
In the field war without smoke of gunpowder, organosilicon is like a magic and powerful new weapon, which has greatly helped farmers to increase production and income.
However, when using this new weapon, we should pay special attention to several points.
One is ready to use, and the prepared solution is used up as soon as possible.
The two is to reduce spray water consumption and speed up the spray walking speed.
Three is spray, should be in accordance with the requirements of pesticide use, wear protective equipment, pay special attention to the protection of the eyes.
The traditional spray method is about 40~50 kg per mu, and the water requirement of fruit trees is doubled. After using a small amount of organosilicon additives, it can be reduced to 15-20 kg / mu. If combined with low volume spray technology, the water consumption per mu can also be reduced to 5~10 kg.
3. Increase spraying area, save water, labor and money.
Farmer friend still has a very concerned problem, after organosilicon auxiliary is used, can be a little bit uneconomical? In terms of increasing the use of organosilicon additives, one is to save water, save labor and improve the control effect of the agent. Recently, we learned from an orange farmer in Guangdong that in the past, 1000 yuan of pesticide was used to make medicine for his orange garden, and 6000 kg of water was added. Now, with the addition of organosilicon, he only used 800 yuan, as long as 4000 kg of water is enough 。 The current labor cost is 175 yuan, which used to be 312.5 yuan. This saves money.
In 2006, organosilicon additives began to be popularized in a large area in China. Its magic power is attracting more and more farmers' interest. Now farmers' friends have another good helper in production. It seems that organic silicon additives are cost-effective and efficient, and they are really good help for farmers.
Silicone features:
Enhance the attachment of liquid medicine, improve the utilization rate of pesticide and reduce the loss of liquid medicine
Excellent wetting and expandability, reduce contact angle between spray and leaf, and increase coverage.
Promote the absorption of the internal absorption agent through the pores and resist the rain wash
Reduce pesticide consumption rationally, reduce spray water consumption, save labour and save time, and save energy and protect environment.
The lower expansibility can promote the internal fungicide and herbicide to diffuse directly into the mesophyll tissue through the stomata of the plant leaves, and play a good auxiliary absorption role.
It can be mixed with a variety of pesticides (insecticide, fungicide, herbicide, foliar fertilizer, biological fertilizer).
Scope of application:
Organosilicon as a spray mixing agent for barrel mixing can be used in combination with pesticides, fungicides, herbicides, plant growth regulators, foliar fertilizers, trace elements and biological pesticides.
What is not suitable for silicone?
In high temperature environment, or the wax of leaves is thin, it is not suitable to add organosilicon, because it may lead to the occurrence of drug damage.
It doesn't matter if the wax layer is thick, but if it is used in the crops with thin wax layer, it will lead to the decrease of water holding capacity of plants, damage of cells, and then drug damage.
Another reason is that if some bactericides with better permeability are added with organosilicon, the efficacy will be too strong; at the same time, the contact herbicides are the same.
Comparison of distribution speed of organosilicon solution
How to distinguish which brand of silicone has good effect?
For example, there are three organosilicon products. First, you can use three paper cups to fill with the same amount of water, and put the same amount of organosilicon into the paper cups at the same level without stirring.
Then select three leaves with uneven surface, and put them in the same horizontal position. Then select three graduated straws or toothpicks of the same size and put them into three paper cups.
Finally, three straws or toothpicks were used to inhale or dip the same amount of organosilicon onto three leaves, and then the following points were observed:
1. See which paper cup is first permeated by the liquid medicine.
2. See which leaf has a wide spread.
3. See which leaves are drying slowly in the air.
4. See which leaves are first permeated by the liquid medicine.
Organosilicon is sold in bottles, barrels and bags on the market. It's more convenient to choose barrels in the field. Many agricultural material stores sell them. At last, we should remind you that when using organosilicon, we must pay attention to the proportion, temperature environment and crop suitability.
