Recently, some farmers have reported that this year's field herbicides are not effective after use. Can pesticides have problems? After the investigation, the author believes that most of them are caused by improper use. There are many factors that affect the herbicide effect. Even if the herbicide of the same species is in different environments or different operating conditions, the herbicidal effect is also very different.
1. The reasons that affect the efficacy of the drug. (1) Temperature. Herbicide efficacy and phytotoxicity have a lot to do with temperature. Such as nicosulfuron, mesotrione, etc. in the lower temperature conditions, the efficacy of slow or poor efficacy. It is easy to produce phytotoxicity under high temperature conditions. Therefore, it is relatively safe for the crop to be applied before and after evening. (2) Weather conditions. Under drought conditions, the efficacy of pesticides often does not work well. After the application of pesticides in the rain, the soil moisture has a good effect; the application of pesticides in windy weather, the drifting of liquid medicines, the poor efficacy, and the ease of migration cause phytotoxicity to other crops. (3) Soil conditions. The effect of closed herbicides is greater, especially in the plots where soil treatment agents are used, the organic matter content is high, and the liquid chemicals are easily adsorbed by the soil, and the dosage needs to be increased. Sandy soils with low organic matter content are liable to leak, leaching, poor film formation, and poor weed control. (4) soil moisture. Good sensation, less absorption of the liquid by the soil, good for weeds absorption, good efficacy. Under drought conditions, the active ingredients of herbicides are absorbed and fixed by the soil and are not easily absorbed by weeds, resulting in poor efficacy. (5) How to use. Water consumption, spray uniformity, missed spray, re-spray, addition of surfactants, etc. have a significant effect on drug efficacy. (6) Weed effects. When the grass age is small, the drug resistance is poor and the efficacy is good; when the grass age is too large, the drug resistance is increased and the efficacy is poor. In weedy conditions, weeds do not germinate, and weeds that have been unearthed are small, but the weeds are old, especially wettable powder products, which have poor adsorption. The sprayed liquid quickly dries and the powder falls off, resulting in poor results.
2. Solution. (1) Soil sealant. After pouring the soil or after the rain the soil moisture is good, use the medicine, according to the instructions to apply the dose, do not arbitrarily increase or decrease, evenly sprayed on the surface of the soil, the formation of film, improve the weeding effect. (2) Post-emergence treatment agent. As much as possible after spraying the ground or after the rain, weeds in the growth state, open stomata, is conducive to liquid absorption; and vigorous plant growth, liquid conduction in the body faster. The medicinal effect is good and the weeding effect is good. When drought occurs, it is necessary to increase the amount of water used. The amount of water used per mu is not less than 30 kg, evenly sprayed, and wetting and weeding stems and leaves of weeds are used to help absorb and transmit water. It is best to use the weeds at the 2-5 leaf stage, when the grass is younger and the weeding effect is better. Silicone additives and other surfactants can be added to the liquid to increase the wettability of the leaves, promote the absorption of the liquid and improve the weeding effect.
Ready-to-eat Double Packed Sweet Corn
In this category is sweet corn from Jilin Province Agricultural Sister-in-law Food Co.
The physical characteristics of maize consist of grain colour, grain shape, seed coat lustre, grain length, grain width, 100 grain weight, grain diameter, uniformity of the seed and hardness. In most cases, the colour of the endosperm of mature maize kernels is yellow or white, while the seed coat and paste layer are colourless and transparent. Depending on the colour of the kernels, there are three types of maize: yellow, white and mixed. Depending on the kernel form, hardness and different uses, maize is divided into two types: common maize (hard, intermediate, horse-tooth, hard-horse, horse-hard) and special maize (high-lysine maize, high-oil maize, sweet maize, cracked maize, glutinous maize).
The sweet corn of Jilin Province Agricultural Sister-in-law Food Co., Ltd. belongs to the special corn category of yellow corn.
Also known as fruit corn. The leaves on the outside are light green (only the ears are in the pack, we have removed the leaves for you) and the kernels inside are white or yellow.
