Description
Technical Field
The invention relates to the field of preparation methods of pesticide herbicides, and in particular relates to an accurate glufosinate-ammonium herbicide.
Background
Refined Glufosinate-ammonium (Glufosinate), chemical name 4- [ hydroxy (methyl) phosphono-phosphonic acid group]-DL-homoalanine of formula C5H15N2O4P belongs to contact type herbicides which are phosphinic acid and have high efficiency, low toxicity, partial systemic absorption and non-conductivity, and different from glyphosate root killing, the refined glufosinate-ammonium firstly kills leaves, is conducted on xylem of plants through plant transpiration, inhibits the activity of glutamine synthetase in plants, causes nitrogen metabolic disorder in plants, and causes chloroplast disintegration and destruction of photosynthesis through excessive accumulation of ammonia, thereby finally killing the plants. Its quick-acting property is between paraquat and glyphosate, and it is easy to degrade in soil, safe for crops, not easy to drift, broad in weeding spectrum and activeHigh dosage and low environmental pressure. The refined glufosinate-ammonium has good water solubility and stable structure, and is convenient to process and mix for use.
Because of the excellent characteristics of the glufosinate-ammonium, the glufosinate-ammonium is very suitable to be used as a resistance gene, the development and planting of the glufosinate-ammonium resistant transgenic crops are rapidly increased in recent years, and the glufosinate-ammonium becomes a herbicide-tolerant variety of the second world transgenic crops except glyphosate.
Bromoxynil is a selective postemergence stem and leaf treatment contact herbicide, is mainly absorbed by leaves, conducts extremely limited in a plant body, and rapidly necroses plant tissues through various processes of inhibiting photosynthesis. The leaves are faded and have necrotic spots within 24 hours after the application of the drug, and the withering of the leaves can be accelerated under the conditions of higher air temperature and stronger illumination. The bromoxynil is suitable for preventing and killing broad-leaved weeds in crops such as corn, sorghum, wheat and the like.
Chlorimuron-ethyl is a sulfonylurea herbicide and is widely used due to the characteristics of high herbicidal activity, wide herbicidal spectrum, strong selectivity, safety to crops, low dosage and the like. Particularly, the herbicide is applied to soil and enters weed bodies to inhibit the synthesis of amino acids such as valine and leucine, prevent cell division and promote the death of weeds. Soybean can metabolize the soybean into inactive substances to grow as usual, so that the soybean is widely used for weeding in soybean fields, which is called as metsulfuron-methyl in China.
The transgenic glufosinate-ammonium-resistant crops have better tolerance to glufosinate-ammonium, and theoretically, under the normal medication condition, the growth and development of the crops are not obviously influenced. However, relevant research data show that after the transgenic crops are sprayed with the herbicide, the growth and development parameters such as plant height, plant diameter, pollen activity and the like of the crops can be slightly influenced, so that the yield is influenced. In particular, the conventional formula herbicide is used instead of the special transgenic formula herbicide, and the components such as solvent, synergist and the like in the conventional formula herbicide can cause serious damage to transgenic crops and even cause phytotoxicity.
The glufosinate-ammonium is used as a hot herbicide, a plurality of related mixed patents are applied in recent years, and no patent and report about mixing of glufosinate-ammonium and bromoxynil or chlorimuron-ethyl is available at present. No report is made on the glufosinate-ammonium herbicide composition and preparation products aiming at the application of the transgenic crops.
