After entering the three-volt weather, most of the crops in China do not need to fight drugs, but for crops grown in summer, it is necessary to do field management techniques. Therefore, weeding is still necessary. When is the high temperature weather? How to fight the herbicide? it is good?

First, from the weather

1. Sunny day

If it is sunny and hot, it is recommended to go to the herbicide after 4-5 pm. Some people say that it is OK in the morning. According to common sense, it is ok before 8-9 in the morning, but Why not recommend it, mainly because the weather is hot and sunny, the herbicide is finished in the morning, the liquid needs to be absorbed (usually about 6 hours), and the weeds are not fully absorbed. The sun at noon comes out. It is evaporated quickly, so that the amount of weeds absorbed by the weeds is reduced, and the weeding effect is compromised. If the herbicide is used after 4-5 pm, after a night of absorption, the weeds will be more satisfactory (the temperature in the night is not low, but it is better than the daytime), so I suggest you go to the afternoon. herbicide.

2, cloudy day

Under cloudy conditions, there is no direct sunlight. After the herbicide is finished, the evaporation of the liquid is relatively not as fast, but the temperature is still very high. It is still necessary to pay attention to this. It is also recommended to fight drugs in the afternoon. For drugs (in the case of dew), you can also fight drugs for the same reasons as above.

In addition, whether it is sunny or cloudy, it is not recommended to fight drugs at noon, there is another reason, that is, safety issues, to avoid heat stroke, if you go to the ground to fight drugs at noon, once the heat stroke, the consequences are not conceived.

Second, from the planting object

1, retail

Retail investors refer to the situation of most of us. There are a few acres of land in the house, planting some crops, leaving some of them to eat, and all the rest are sold, in exchange for some income. If you are a retailer, the time for herbicides is the same as above. Say the same, no matter whether it is sunny or cloudy, under high temperature conditions, it is recommended to fight drugs in the afternoon or evening. For example, if there are 5 mu of land in the house, they are all planted corn. Sometimes, the 5 mu of land is not even block. There may be several places, you need to ride a tricycle, pull the medicine bucket to run around, if you can't finish the day, then two days, basically two days can be finished, and will not affect the crop.

2, large households

Large households can be large farmers, cooperatives, farms, etc. In this case, we have to say something differently. Why? Everyone knows that during the period of fighting drugs, large employees hire more people (or fight drugs themselves), usually by day. Wages, but also have to take care of the meal, if you let them wait until 4-5 pm to fight drugs, do that for a few hours a day, do not say that the owner is willing or not, wait until the end of the fight (in the case of thousands of acres), the ground The weeds are very tall, the weed resistance is enhanced, and the effect is not achieved. It is equal to white work. Therefore, for the situation of large households, it is recommended to fight drugs according to the actual situation, and you can avoid the two hours of noon. When it is particularly hot, if there are a lot of plots, you can also work overtime at night to fight drugs (with the equipment can see clearly).

In addition, when you hit the herbicide, you will be reminded of 3 points:

1, the herbicide dose can not be increased arbitrarily, some friends will think that the application of high temperature, evaporation, increase the dose, this is wrong, in the best suitable period of weeds, according to the instructions for use.

2. The herbicide is recommended to be diluted twice. After mixing in a small container, it is poured into a large container, whether it is a human back sprayer, a fightr or a drone.

3. Under the premise that the herbicide dose is fixed per unit area, the more water the better, the grass is penetrated. In this way, the weeding effect can achieve our goal.
