AI Technical Summary

Problems solved by technology

In addition, herbicide residues in the soil affect the persistence of herbicides and the safety of the environment
From the aspect of weed control, herbicides should have a certain residual period. If the residual period is too short, the weeding effect will not be good, but if the residual period is too long, it will cause phytotoxicity to the recommended crops.
However, from an environmental point of view, the shorter the residual period of herbicides, the better. Herbicides are too stable, not easy to degrade, and have a large amount of residues in the environment, which will cause environmental pollution.

preparation example Construction

[0034] The preparation method of described octylphenol polyoxyethylene ether sulfonate and heavy alkylbenzene sulfonate mixture comprises:

[0035] The first step, the chlorination of octylphenol polyoxyethylene ether;

[0036] Second step, sulfonation of octylphenol polyoxyethylene ether after chlorination

[0037] In the third step, mix octylphenol polyoxyethylene ether sulfonate and heavy alkylbenzene sulfonate according to (2.5-4): (1-1.5).

[0038] The first step is further specifically adding octylphenol polyoxyethylene ether (OP-4) and pyridine into the reaction vessel at a molar ratio of 1:1, adding thionyl chloride dropwise under constant temperature water bath conditions, chlorine The molar ratio of sulfoxide to octylphenol polyoxyethylene ether was 1.5:1, stirred and reacted at 70°C to 80°C for 2 hours, and chlorooctylphenol polyoxyethylene ether was synthesized.

[0039] The second step is further specifically adding chlorooctylphenol polyoxyethylene ether to wat...

[0049] Embodiment 1 octylphenol polyoxyethylene ether sulfonate and heavy alkylbenzene sulfonate mixture

[0050] Mix 10 mol of octylphenol polyoxyethylene ether (OP-4) and 10 mol of pyridine into the reaction vessel, add 15 mol of thionyl chloride dropwise in a constant temperature water bath, stir and react at 80°C for 2 hours, and synthesize chlorooctyl Base phenol polyoxyethylene ether, get the obtained 7.5mol chlorooctylphenol polyoxyethylene ether and join in water, the mass ratio of chlorooctylphenol polyoxyethylene ether and water is 1:1.5, then add 5mol sulfonating agent Sodium sulfite (Na 2 SO 3 ), placed in a high-pressure reactor, and reacted at 150°C for 8 hours under vigorous stirring to obtain a light yellow viscous substance. The crude product was dissolved in a mixture of isopropanol and water with a volume ratio of 2:1, and then extracted with petroleum ether , to remove unreacted raw materials and other oil-soluble impurities, separate the lower layer, dis...

Abstract

The invention provides a herbicide compound specially used for removing alternanthera philoxeroides. The raw materials of the herbicide compound comprise effective active ingredients and a surfactant, wherein the effective active ingredients comprise quinclorac, N-(phosphonomethyl)glycine, imazapic and chipton. The herbicide compound provided by the invention has the excellent effect on removing alternanthera philoxeroides weeds in a blueberry field and is safe, efficient, good in drug degradation effect, and fewer in residue.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide compound and herbicide microemulsion specially used for removing water peanuts in blueberry fields. Background technique [0002] Alternantheraphiloxeroides, formerly known as: Helicopteris albicans, aliases: Amaranth, water spinach, revolutionary grass, water peanut, Latin name: Alternantheraphiloxeroides (Mart.) Griseb. Upper part ascending, tubular, not obvious 4-ribbed, branched, young stems and leaf axils with white or rust-colored pilose, stems glabrous when old, only retained in the longitudinal grooves on both sides. Leaf blade oblong, obovate or obovate-lanceolate, base united into a cup shape; staminode oblong strip, about as long as stamens, apex split into narrow strips; ovary obovate, with short stalk , dorsally flattened, rounded apex. In blueberry planting fields, there is often water competition between peanuts and blueberries for fertilizer and w...
