How many levels of corn herbicide can not be blown by the wind?

Corn herbicides cannot be sprayed in winds greater than level 3. Because when the wind is greater than level 3, the spray of herbicide will drift to the corn when the sprinkler head is depressed, causing pesticide damage. At the same time, it is best to avoid high temperature periods at 6 a.m. to 9 a.m. and from 4 p.m. to 7 p.m.

In addition, there are a few things to keep in mind when using corn herbicides:

1.Fine leveling of the land.

2.Plots with few surrounding nectar plants and heavy weed damage should be pulled out one by one after the weeds are ready.

3.Correct choice of herbicide.

4.Master the spraying time.

5.Master the climatic conditions for spraying.

6.Understand the growth of crops in the field and the condition of the plots.

7.Administer according to the recommended dose.

8.The herbicide is selected according to the soil type and ground vegetation.

9.Try to avoid applying pesticides in rainy days.

10.Spray herbicides in time after harvest of the previous crops.

11.The land should be leveled to avoid inconsistent concentrations of liquid medicine due to the undulations of the ground.

12.Soil treatment and stem and leaf treatment are correctly selected and used according to different crops, weed species, pesticide application time, climatic conditions, etc.

Wind force 3 can't be played.

When the wind is level 2, you can appropriately lower the sprinkler head to fight, so as not to be floating.

When 3 doses of wind, try not to hit. One is to hit the target. Second, it is easy to drift to adjacent sensitive crops.

Note: It is also necessary to avoid high temperature time for spraying. Try not to apply medicine when the temperature is above 28 degrees.

Your herbicide can't be beaten by the wind, and it is generally six or seven knots that can't be amplified.

Summary. Hello, I have helped you find the result; Corn seedlings are affected by herbicides. If the corn seedlings are hit by wind and sand, the leaves of the corn plant will be damaged, which may seriously affect the normal growth and development of the plant.

Herbicides generally have a certain toxic effect on corn seedlings, and can also have adverse effects on corn seedlings in excessive doses or improper use. If herbicides are used after the corn seedlings encounter sandstorms, first of all, you need to pay attention to the dosage and use of the pesticides, ensure that the standard dosage is not exceeded, and do not overwater, so as not to inhale too much pesticides in the corn seedlings. In addition, it is necessary to identify the different characteristics of herbicides such as meadadolin, AUO and paraquat, select suitable agents, and avoid using pesticides that are effective for non-target crops such as corn.

For corn seedlings that have been hit by sandstorms, the adaptability of the plants to the environment can be strengthened by timely watering, fertilization, spraying of biological fungi or growth regulators, etc., so as to promote their growth and recovery. When using herbicides, you should also pay attention to the use period and safety interval of the agent, and follow the recommendations on the instructions for use.

In addition, it is necessary to identify the different characteristics of herbicides such as Turva, AUO, and Paraquat, and select suitable agents to avoid the use of pesticides that are highly effective for non-target crops such as corn. For corn seedlings that have been hit by sandstorms, the adaptability of the plants to the environment can be strengthened by timely watering, fertilization, spraying of biological fungi or growth regulators, etc., so as to promote their growth and recovery.

Can corn clover be herbicide.

Corn three-leaf one-heart means that the three leaves on the corn seedling have been opened, and the top of the leaf has not yet differentiated into new leaves. At this time, the leaf area of the corn seedlings is already large, which is suitable for the application of some herbicides. However, not all herbicides can be used during the three-leaf period of corn.

Depending on the type of herbicide used and the dosage used, corn seedlings may respond differently at different stages of growth. In general, herbicides suitable for moulding such as corn should be selected and applied in accordance with the standard dosage of the label. In addition, it is also necessary to pay attention to the period of application of herbicides.

For some herbicides, there may be a specific time period or growth stage that is applicable, such as postponing the grip to the four-leaf or six-leaf stage.

No!

Among the herbicides in corn fields, especially post-emergence herbicides in corn fields, atrazine is used. The soil residue period of atrazine is relatively long, especially for the broad-leaved crops after stubble, which has a greater impact.
