Early use of "Kaipu" to block weeds and broad-spectrum efficient rice and barley fields

In the past ten years, weeds in wheat fields have become more and more serious, and we have formed a great deal of support for the safety production of small (large) wheat. The main reasons for the analysis of experts are several aspects: First, the province's small (large) wheat planting is generally delayed, and the farming methods are diverse and the ecological environment is complex. Tillage methods include no-tillage, shallow-rotation, deep-rotation, deep tillage, rice paddy, etc. Rice straw returning also increases the complexity of the soil surface habitat. Usually, rice straw and wheat stubble are less than no-tillage wheat straw. serious. The second is that the grass is complex and most of the fields are endangered by a mixture of many grasses and broad-leaved weeds. Thirdly, the problem of weed resistance is becoming more and more serious. Anti-aryloxyphenoxypropionate herbicides such as fenoxaprop-yl, clodinafop-propargyl, grasses such as Japanese amaranth, and anti-sulphonylureas The herbicide tribenuron-methyl, such as broad-leaved weeds of broadleaf weeds, leeks, and broadleaves, is widely distributed. Fourth, the herbicide formulations used cannot be used to target weed populations in rice and wheat fields. Fifth, the commonly used formula of rice straw herbicides in wheat fields is prone to phytotoxicity due to cold currents, and the weather in the early winter and early spring is variable. The appropriate period of application is short and easy to miss. Sixth, there is no guarantee on the quality of pesticide application equipment and application, and the amount of water used is not enough and the spraying is uneven.

In view of the occurrence characteristics of grassland damage and the existing problems of control, experts believe that a comprehensive plan for prevention and control of grassland damage in rice and wheat fields should be established, and farming and cultivation should be adopted to control grassland damage in combination with comprehensive measures for preventing and controlling winter and early winter chemicals. The first is that severe grass-eaten plots should be ploughed in rice stubble, planted with soil, and then pressed to raise the level of soil surface. These measures are not only conducive to the emergence and early growth of small (large) wheat, but also can reduce the occurrence of weeds in wheat field, shorten the weeds to the peak of grass, and increase the efficiency of pre-emergence and post-emergence early sowing. The second is based on the post-planting seedlings or early post-emergence (early winter early) elimination, early winter (in late February) supplementary treatment measures. Pre-winter and early winter application should use the combination of soil sealing and stem and leaf treatment, broadening the spectrum of grass (for the main hazards of weeds and resistant weed populations), long duration, and use during low temperature and cold period is safer for wheat seedlings. Herbicide or formula. The third is to avoid the first post-post-emergence cold spraying (in late November) and post-emergence application to reduce the possible "frozen phytotoxicity." The fourth is to ensure the quality of the application, water consumption per mu is not less than 30 kg, the entire field surface fine spray uniform.

Kaipu 47% isoprenc chloride WP is the Jiangsu Agricultural Production Information Group Agricultural Chemical Co., Ltd. for the characteristics of the cultivation of rice and wheat in our province and the main hazards of resistant weed population? Grass, Japan to see Auntie and other newly introduced Ternary mixed herbicides. This medicine can be effectively used to control resistance after small (large) wheat sowing before seedlings and early after seedling emergence. Grass, Japanese Acacia, Mai Auntie, Hard Grass, Poa pratensis, Cattle Stallion, Seaweed, Big Lamb A variety of weeds such as leeks, leeks, and gray green pods are available. From 2014 to 2015, the trial results of rice bran, wheat, wheat and wheat in 50 counties (cities) across the province showed that “Kaipu” can be used in wheat and barley fields. Before sowing, we can use 180-200 per acre before weeding. Grams, adding water 30 kg evenly sprayed on the soil surface, with high safety, broad spectrum of grass, wide use of appropriate period, long duration, good effect.
