Description
Technical Field
The invention relates to the technical field of pesticides, in particular to a silybum marianum chemical weeding composition, and particularly relates to a silybum marianum chemical weeding composition, wherein the effective components of the silybum marianum chemical weeding composition comprise flubensulfuron-methyl, phenoxy carboxylic acid and benzoic acid herbicides: comprises 2, 4-D and ester, acid and salt thereof, 2-methyl-4-chlorine and one or more of sodium salt, amine salt, dimethylamine salt and dicamba.
Background
Silybum marianum is a perennial or biennial herb of Silybum of Compositae, and is an excellent liver-protecting plant, and the whole herb is used for carbuncle and erysipelas; the fruit and the extract thereof have the functions of clearing away heat and toxic material, protecting liver and gallbladder, reducing blood fat, protecting cardiac muscle, protecting brain and resisting X-rays, and have good curative effects on liver and gallbladder diseases such as acute and chronic hepatitis, cirrhosis, fatty liver, metabolic poisoning liver injury, cholelithiasis, cholangitis, perihepatocholangitis and the like. Silybum marianum likes cool and dry climate, has strong adaptability and non-strict requirements on water and fertilizer conditions, and has large-area planting in northeast, northwest and northwest areas of China, wherein the northeast area is the main production area of Silybum marianum in China, and the yield accounts for more than 70% of the whole country.
The main problems faced by the current chemical weeding of silybum marianum are poor weeding effect, serious phytotoxicity to silybum marianum and serious influence on yield. Currently, the betanin is mainly used as an after-seedling herbicide in a silybum marianum field, the herbicide is low in use concentration, the silybum marianum cannot kill weeds, the silybum marianum is serious in use concentration, the herbicide is narrow in weed killing spectrum, and the herbicide has no effect on a plurality of weeds after being used for many years, such as the weeds of chickweed, wild carrot, polygonum cuspidatum, artemisias, chenopodium glaucum and the like, becomes a main harmful weed in the silybum marianum field, and causes huge loss on large-area planting of silybum marianum.
Phenoxy carboxylic acid and benzoic acid herbicides are phytohormone herbicides which have strong selectivity, broad herbicidal spectrum, low cost and easy industrial synthesis, have physiological effects similar to auxin (IAA), can be used for plant growth regulation, and are one of the commonly used auxin analogs for inducing callus formation. The herbicide has low concentration for promoting plant growth and high concentration for inhibiting plant growth, and can be used for preventing and killing broad-leaved weeds such as descurainia sophia, chenopodium album, cleavers, polygonum, mustard, ionophora, chickweed, amaranthus retroflexus, humulus scandens, field horsetail, sowthistle herb, aralia elata, xanthium sibiricum, Convolvulus arvensis, purslane and the like, and has systemic property. Can enter the plant body from roots, stems and leaves, is slowly degraded, and can accumulate a certain concentration, thereby interfering the hormone balance in the plant body, destroying the metabolism of nucleic acid and protein, promoting or inhibiting the growth of certain organs, and leading the stems and leaves of weeds to twist, the stem bases to become thick, the swelling and cracking and the like. The fertilizer is used for soil treatment after sowing and before seedling emergence to prevent and eliminate various monocotyledonous and dicotyledonous weeds.
Triflusulfuron-methyl (triflusulfuron-methyl CAS number: 126535-15-7; chemical name: 3- (4-dimethylamino-6- (2, 2, 2-trifluoroethoxy) -1, 3, 5-three-Hash-2-aminomethylphthaleinesulphthal) methyl m-methylbenzoate) sulfonylurea herbicide. Inhibiting the synthesis of acetolactate synthase (ALS) of plants, blocking the biosynthesis of side chain amino acids, and thus affecting the division and growth of cells. Can prevent and kill a plurality of broadleaf weeds and gramineous weeds in the beet fields, and has high safety.
On the basis of years of indoor screening and field experiments, the triflusulfuron-methyl is screened out to be compounded with phenoxy carboxylic acid and benzoic acid herbicide to prevent and control various broad leaf weeds and part of gramineous weeds in a silybum marianum field, so that a good effect is achieved, the pesticide damage to silybum marianum is small, and the yield and the quality of silybum marianum can be effectively improved.
