High temperatures and dry weather have affected the effects of herbicides on corn seedlings, and many farmers have asked about this. In order to allow more farmers to use medicine scientifically and spray the herbicides after corn seedlings, the following guidance is proposed. First, the spraying time requires 2 to 6 hours of absorption after the spraying of the herbicides in the corn seedlings. In these 2 to 6 hours, the effect of the drug is good (that is, whether the herbicidal effect is ideal) and the temperature and air. The humidity is very close. Spraying in the morning, noon or afternoon when the temperature is high and the weather is dry, because the temperature is high, the light is strong, the liquid evaporates quickly, and after a spraying, the liquid will evaporate, so that the amount of the herbicide entering the weed body is limited, and the absorption is limited. The amount is obviously insufficient, which affects the herbicidal effect; at the same time, when spraying at high temperature and drought, corn seedlings are also prone to phytotoxicity. The best spraying time is after 6 o'clock in the evening, because the spraying at this time, the temperature is lower after application, the humidity is larger, the liquid stays on the weed leaves for a longer period of time, and the weed can fully absorb the herbicide. The ingredients ensure the herbicidal effect, and the evening medication can also significantly improve the safety of the corn seedlings, and it is not easy to cause phytotoxicity. Second, the spraying method for the amount of mud used for 15 to 30 kg of water, see grass spray, spray carefully, no grass to go, save medicine and save time. Third, look at the size of the spray spray spray corn seedlings herbicide, many farmers have a misunderstanding, that the smaller the weed, the smaller the resistance, the easier the grass to kill. Actually, it is not the case. Because the grass is too small, there is no medicine area, and the weeding effect is not ideal. The best grass age is 2 leaves 1 heart to 4 leaves 1 heart period. At this time, the weeds have a certain area of ​​medicine, the weed resistance is not large, and the weeding effect is remarkable. Fourth, corn seedling size corn seedlings herbicides the best spraying time is corn 2 to 5 leaf stage, at this time corn resistance is high, not easy to appear phytotoxicity. 5 leaves can be sprayed in the whole field before the leaves, spray after 6 leaves, to lower the nozzle, spray around the corn, to prevent the drug from causing damage. 5. Corn Varieties Because most of the herbicides in corn seedlings are currently consisting of nicosulfuron, some corn varieties are sensitive to this ingredient and are prone to phytotoxicity. Therefore, corn fields such as sweet corn, waxy corn and Denghai series cannot be sprayed. Apply to prevent the occurrence of phytotoxicity. For new corn varieties, please test and promote. 6. Mixing of pesticides 7 days before and after spraying the herbicides, it is strictly forbidden to spray organic phosphorus insecticides, otherwise it is prone to phytotoxicity. However, it can be mixed with pyrethroids and carbamate insecticides. When spraying, pay attention to avoiding happy leaves and anti-drug solution. This year, some corn fields have serious occurrences of Swedish flies and thrips. The two small pests can be sprayed with imidacloprid or acetamiprid, but they should not be sprayed with post-emergence herbicides, although imidacloprid or acetamiprid is not organic. Phosphorus, because it is necessary to spray the heart leaf to prevent and control two small pests, if it is mixed with the heart leaf, it is easy to cause phytotoxicity. It can be sprayed separately: the herbicide is sprayed on the front side, followed by the spray of the heart leaf with imidacloprid or acetamiprid. 7. Weeds' own resistance Because of the high temperature and drought this year, the weed resistance of weeds has been strengthened. In order to prevent excessive evaporation of water in the body, weeds grow not so watery and thick, but grow gray and short. The actual age of the grass is not small (the so-called "little old man"). Most of these weeds are covered with white small fluff to reduce the evaporation of water. When spraying pesticides in this way, the liquid is topped on the surface of the weed stems and leaves, and the weeds themselves absorb very little, which naturally affects the exertion of the drug effect. Therefore, no matter what medicine is applied during high temperature and drought, it should be added. The amount of liquid sprayed (usually not less than 40 kg per acre), so as not to affect the exertion of the efficacy of the drug, please do not hesitate to take the medicine when applying pesticides.
