If you say that a farmer will not spray medicine, it is just like saying who is a layman! In fact, there are not many people who can really do scientifically spray pesticides. How do you spray them scientifically? How much water should a bottle of pesticides be? Many farmers are still not very clear. Recently, Xiaobian discovered an easy-to-understand pesticide dosage form, and the comparison form quickly found the required dose.

The number in the pink area is the amount of water exchanged; the number in the yellow area is the amount used; the number in the green area is the dilution factor. It's very convenient to find. You only need to compare the horizontal row and the vertical column of the table to find the number at the intersection to know the dose.

For example, if we need to prepare a diluted drug that is 3000 times diluted and we need to weigh 60 pounds of water, then we will find the number 3000 times from the leftmost side, and then find 60 pounds in the upper right water volume to find the crossed number. The amount of the required dose can be obtained, which is 10 ml or 10 g.

In addition, scientific spraying of pesticides requires mastering the following principles:

Grasp the timing of spraying

It is common for vegetable farmers to get used to spraying medicine for three or four days, thinking that they can sit back and relax. In fact, this method is very wrong, not only the cost is increased, but also the drug is particularly prone to cause rapid increase in pest resistance, so that it cannot be controlled when it occurs.

A reasonable method is to use the drug at the beginning of the pest, and the disease is recommended to spray a protective fungicide on a regular basis. At the beginning of the disease, a symptomatic therapeutic fungicide is taken according to the type of the disease.

Suitable amount of liquid spray

The amount of liquid spray is not as good as possible. Usually, there are often vegetable farmers who ask me to spray a few barrels of water when spraying. In fact, this is a problem that cannot be answered. The most reasonable amount of liquid spray when spraying is to spray the leaves to the surface and it is just the best. good.

科学实验表明,如果喷洒叶片后留在叶片上的液体量只是液体落在叶片上的一半左右,喷洒滴水时不仅造成大量废物,而且实际控制效果很大。折扣。

一些蔬菜农民习惯于很少喷洒液体,药物浓度很高。这也是不科学的,因为它不仅容易发生植物毒性,而且泄漏现象严重,目标不喷雾,控制效果不理想。

不同的控制目标,不同的喷雾位置

如果喷洒药物来控制蓟马,螨虫和粉虱等害虫,请关注植物的幼稚或中部。如果控制了一般疾病,重点是喷洒中间和下部容易受影响的老叶。对于疾病,如病害,枯萎病和枯萎病,应严格喷洒茎的基部。

液体溶液的制备

使用药液时,建议采用二次稀释法,即将农药溶于少量水中,然后均匀加入水中,使药剂更均匀地溶解于水中。效果更好。

农药混合序列

如果你一次喷洒各种杀虫剂,如杀虫剂,杀菌剂,叶面肥等,你必须记住,当你分配药液时,必须先加入叶面肥,然后加入粉末杀死或杀死粉末。杀虫剂,最后添加乳液类型的农药。按此顺序,药物的功效受到的影响较小,相反,它可能对各种农药的影响产生很大影响甚至失败。

完成
