Attention Farmer Friends! After the year, wheat herbicides should be used with caution to cope with the cold wave and prevent pesticide damage
After New Year's Day, the application of herbicides should be postponed in wheat fields.
After the Spring Festival, farmers all over Henan asked their "little assistants" if they could use the high temperature period to spray pesticides on their wheat, so that they could manage their fields as soon as possible. After the second day of the first lunar month, everyone in the family is gone, and every family is busy with spring farm work, the most important of which is wheat. When the wheat begins to turn green, the weeds in the wheat field will also grow wildly, especially the wheat field that was not hoeed last year, and it is necessary to remove it as soon as possible. However, the weather conditions for the year are difficult to **. According to the Meteorological Observatory, from February 17 to 22, there will be a cold air attack in our country, the temperature will plummet, and it is not suitable to apply pesticides in the short term, so this work needs to be postponed.
As a precaution, don't apply herbicides indiscriminately before a cold snap hits.
The cold spell coincided with a sudden change in climate, especially a sharp drop in temperature, which was not conducive to herbicide spraying in wheat fields. So, he had to be prepared. Due to their use in adverse climatic conditions, wheat herbicides can produce undesirable results. It should be sprayed when the weather is sunny and the temperature is moderate, so as to achieve twice the result with half the effort.
Effects of meteorological factors on weeding in wheat.
At present, the various types of wheat herbicides on the market are diverse, with different compositions and different ecological adaptability. After the emergence stage of wheat, weeding is mainly internal absorption, rather than direct contact. The herbicide undergoes a period of adsorption before it takes effect, and when it rains, the content of the herbicide is diluted, thus reducing the efficacy of the herbicide. In addition, due to snow, the temperature will also drop, which is a big factor. If the temperature is too cold, it will not only reduce the medicinal effect of the grass, but also increase the damage to the wheat field.
Change the world and choose the period of pesticides carefully.
Pay attention to weather conditions when choosing the right time to spray wheat herbicides. The temperature outside was good, preferably sunny, with no rain or snow. In this way, in the best case, the effect of the herbicide will be maximized, ensuring that the wheat grows in a fresh and clean environment, ushering in a vigorous spring.
Tip: Wait until the cold snap is over.
After learning about this year's meteorological conditions and the cultivation characteristics of wheat, the assistant reminded farmers to avoid using wheat herbicides as much as possible before the arrival of cold air. It's warm right now, but be careful and wait until the temperature rises. In the process of agricultural production, the role of weed control is important, but timely treatment can reduce unnecessary losses and dangers.
To win safely, use wheat herbicides carefully.
Therefore, it is very necessary to choose the right time for spraying. This is not only out of love for crops, but also out of appreciation for the hard work of farmers. In agricultural production, prudent measures can often achieve more than twice the effect, and I sincerely wish that every farmer can work steadily and obtain satisfactory harvests.
The conclusion: during the planting process, the field work should be carried out carefully, paying special attention to the time of spraying. When the cold wave is coming, the peasants should be vigilant and not act rashly. Postponing the spraying of pesticides and waiting for the temperature to warm up is undoubtedly beneficial to promote the normal growth of wheat. We hope that the majority of farmers can have more practical experience, and on this basis, organize every work scientifically and rationally, and reap fruitful fruits.
