What are some tips for spraying pesticides?

Before we spray pesticides, we must clean up some bad leaves, withered branches, and some broken branches in the fruit trees, clean them into a pile and burn them with fire, so that they can kill a lot of fungi, and can be used as organic fertilizer, and then spray pesticides, often the effect will be better。Don't underestimate this step, if you do this step well, then some insects and some fungi hiding in some dead leaves, or in some broken branches, are often easy to kill. <>

When spraying pesticides, it is necessary to grasp the active time points of these pests and diseases, and spray pesticides according to their active time points. If the pests and diseases are not active, it is difficult for us to spray pesticides to directly react to the insects, only when they are active, we spray again, then we can kill most of the insects. <>

If it rains when spraying pesticides, then you need to respray them. In fact, one of the most worrying things about spraying pesticides is rain, once it rains, the pesticides we spray are often easy to lose their efficacy. Pesticides are soluble in water, and when the rain washes them, it is very likely that some pesticides on the surface of the leaves will be diluted, which will affect the absorption of drugs by crops and reduce some damage to some insects.

Spraying pesticides is generally done at intervals of 3 to 5 days, up to a week, and a booster spraying is required. This step cannot be ignored, because a large number of germs and insects cannot be killed at one time, so it also needs to be strengthened once. Because the pesticides we spray at one time are not particularly comprehensive, if we can do it comprehensively without leaving dead ends, it will be better, but for the sake of insurance, it is still necessary to carry out secondary killing.

The dilution of pesticides is reasonable and compliant. Now pesticides will have a certain manual, according to their proportion, can not be more or less, more will be wasted, less money will not be effective.

You can also mix a little fertilizer or insecticide in pesticides, spray crops, spray crop roots, spray the land, and spray the leaves of crops.

First of all, it is necessary to choose the right pesticide according to the crop, and then choose the right location, and at the same time, you should also pay attention to the right time, do not choose to spray pesticides when the temperature or rain is relatively heavy, you must pay attention to the dose.

Because of the high temperature weather, due to the relatively high temperature, the water falling on the leaf surface of the plant is easy to evaporate, at this time, the spraying is easy to make the concentration very high, easy to produce pesticide damage, and also because the high temperature liquid evaporation too fast will cause waste. At the same time, due to the high temperature time, spraying pesticides in high temperature weather will speed up the decomposition of pesticides, and crops in high temperature weather, metabolism is relatively vigorous, and the agent is easier to enter the crop body, resulting in pesticide damage. It is also easier to cause heat stroke to sprayers.

The most important thing for pesticide mixing is to test its pH value, whether it is acidic or salty, if it is both acidic or salty, it can be mixed and sprayed together, otherwise, it can not be sprayed together. Generally speaking, in the environment of high temperature and scorching sun, it is easy to cause poisoning of pesticide applicators and crop pesticide damage, so it should be avoided to spray pesticides around noon in hot weather, even if high temperature has the effect of improving the efficacy of some pesticide varieties.

In general, it is not recommended to spray pesticides in farmland in hot weather. The risk of safety accidents caused by worker poisoning and fertilizer and pesticide damage to crops has also increased exponentially. However, in the actual production process, at present, the crops to be sprayed with pesticides in rural areas include rice, cotton, corn, soybeans, sesame, etc., but at present, the hot weather in June is not to work in the field, even if you stay at home and relax at every turn, you are sweating profusely.

Mineral oil spraying is more sensitive, and copper preparations are also sensitive; Spraying mineral oil must be done away from hot days. It is recommended to use organic copper in copper preparations, which will be relatively safe, but it is also necessary to reduce the dosage and mix more with water.

Medication temperature: Whether it is bacteria or some other plants, their most active temperature is generally about 25°, at this time the medication is the most appropriate, because they are more active at this time, and the effect of the medicine is better when spraying. Improve the utilization rate of pesticides and pay attention to increasing the adhesion of pesticides.

When using pesticides in open crops, it is more appropriate to choose rain-resistant erosion, emulsifiable concentrate, etc., these pesticides remain on the surface of the plant for a long time, and powder, water agent, etc. are relatively poor.

After the liquid sprayed from the nozzle is deposited on the target, it needs to form a uniform film to cover the surface of the target to the greatest extent, and then kill the pests and diseases on the target. The deposition of the chemical solution will be affected by a variety of factors, among which the air humidity is greatly affected.

When spraying, do not spray directly on the crop itself, be sure to spray it around at a certain distance. And also choose the corresponding pesticides. In this way, it can effectively defend against pests and diseases.

And after spraying, it should also be watered in time to help our crops better absorb nutrients.

When spraying, you can spray back and forth, be sure to spray evenly, be sure to pay attention to the back of the leaves also need to be sprayed, pay attention to your own spraying situation, and choose the right watering can for spraying.

Be sure to spray evenly, but also pay attention to the scope when spraying, but also to dilute it appropriately, try to choose pollution-free pesticides, and try to choose pesticides that are not very harmful.

Spraying, watering, root application, powder spraying, sprinkling, seed dressing, these are very basic pesticide skills.

You can choose to spray, you can also choose to apply to the roots, or sprinkle pesticides, you can choose to dress the seeds, or soak them, and you can also spray some powder to achieve the effect of applying pesticides.

The first thing is to choose the right pesticide, when using it must choose the right time, be sure to avoid rainy days or when the temperature is relatively high, and then be sure to pay attention to the appropriate dosage, and at the same time be sure to pay attention to the variety of crops, and then choose the right one.

To choose the right pesticide for spraying according to the situation of the plant, we must pay attention to safety, pay attention to the ratio, we must choose the right climate, choose the right weather for spraying, and can be used in proportion with other pesticides.

Reasonable application techniques are, 1 stay away from crowds, 2 do not let children touch, 3 remember to wear gloves and masks, 4 do not mix them, so that it will be safe.
