Description
Technical field
The present invention relates to a kind of fomesafen aqua synergistic formula composition, belong to technical field of pesticide.
Background technology
Fomesafen：English common name：Fomesafen chemical names：5-2（2- chloro- a, a, a- tri- is fluoro- to toluene
Epoxide）- N- mesyl -2- nitrobenzamide CAS NO.：72178-02-0 relative molecular weights：438.8 molecular formula：
C15H10ClF3N2O6S physicochemical properties：Active compound is light yellow solid.Solubility：120mg/L in water（23-25℃）；In acetone
600mg/L, 500mg/L in ethanol, 50mg/L, dimethylbenzene, kerosene ＜ 10g/kg in dichloroethanes（25℃）.Stability：235℃
Decompose.40 DEG C of temperature is stable during PH3-9.Fomesafen sodium salt aqua is can be made into after being neutralized with sodium hydroxide, the aqua is one
Kind diphenyl ether selective post-emergence herbicide, can be absorbed by weeds cauline leaf and carry out limited conduction, fast with the speed that takes effect,
Herbicide spectrum width, it is safe the features such as, be mainly used in Soybean Field lamb's-quarters, piemarker, amaranth, knotweed, Siberian cocklebur, black nightshade, dayflower etc. a variety of one
Year raw broad leaved weed is prevented and kill off.
Glycine：White monoclinic system or hexagonal crystalline, it is odorless, there is special sweet taste.Relative density 1.1607.Fusing point
248 DEG C (decomposition).PK'1 (COOH) is that 2.34, pK'2 (N+H3) is 9.60.It is soluble in water, the solubility in water:At 25 DEG C
For 25g/100ml;It is 39.1g/100ml at 50 DEG C;It is 54.4g/100ml at 75 DEG C;It is 67.2g/100ml at 100 DEG C.It is extremely difficult
Ethanol is dissolved in, about dissolves 0.06g in 100g absolute ethyl alcohols.It is practically insoluble in acetone and ether.Hydrochloric acid is generated with hydrochloric acid reaction
Salt.PH (50g/L solution, 25 DEG C)=5.8 ~ 6.4.
Conventional aqua formula is mostly to be configured using fomesafen active compound and caustic-soda aqueous solution in the market
Into fomesafen sodium salt aqua, while add the surfactant such as fast T of APG, bleeding agent, nonyl phenol in aqua and gather
Oxygen vinethene, organosilicon etc. increase the permeability of medicine, improve the herbicidal effect of preparation.But with making for the product throughout the year
With, the weeds serious resistance to the action of a drug to the product formation in main soybean producing region, its 25% aqua product mu dosage from
Incipient 50 ~ 80 milliliters bring up to more than 200 ~ 300 milliliters of today, and herbicidal effect is still undesirable, and product formula is badly in need of rising
Level transformation, lift the preventive effect of preparation antagonism weeds.
The content of the invention
The present invention is directed to drawbacks described above, and it is an object of the present invention to provide a kind of rational technology, and one kind of herbicidal effect can be greatly improved
Fomesafen aqua synergistic formula composition.
It is for this technical solution adopted by the present invention：The present invention is calculated in mass percent containing fomesafen active compound 20%
- 50%, wetting and penetrating agent 2% -20%, amino acid 0.1- 20.0%, deionized water complements to 100%.
The amino acid is glycine.
The content of the amino acid is 1 ~ 10%.
Preferably, the content of the amino acid is 2 ~ 5%.
The glycine purity is 98%.
The amino acid is the mixture of glycine and threonine, by mass percentage the glycine：Threonine=
65-85:15-35%。
Also include glutamine, by mass percentage the glycine：Threonine:Glutamine=65-85:10-
25:5-10。
It is an advantage of the invention that：In the present invention in common fomesafen sodium salt aqua, it is added into a certain amount of sweet
Propylhomoserin, there can be a qualitative leap to the herbicidal effect of fomesafen sodium salt aqua, especially in these years more next
It is more difficult to obvious with the preventive effect lifting of the anti-bitterroot of preventing and treating.Glycine does not have activity of weeding in itself, simply can during biological growth
With the common amino acid utilized, but it can significantly promote soybean and weeds to moisture with supporting after being added to aqua product
Material absorbs, while also promotes soybean and absorption of the weeds to fomesafen active compound, because soybean itself has to fluorine
The higher tolerance of sulfanilamide (SN) grass ether, fomesafen can be decomposed into discharge by innocuous substance by the metabolic enzyme of itself quickly
In vitro, weeds, particularly anti-bitterroot can not directly be metabolized the biology enzyme of fomesafen, with the addition of in vivo in itself
After glycine, weeds increase considerably to the uptake of fomesafen, and the detoxification ability of itself does not have synchronous increase,
So weeds are just shown with very strong toxic action, it is more vigorous then to show as the growing way of soybean after medication in crop field,
And weeds production is suppressed obvious.Under normal recommended dosage, it is not added with the product of glycine its preventive effect to anti-bitterroot and typically exists
40 ~ 50%, and its preventive effect to anti-bitterroot can reach more than 90% after with the addition of 5% glycine, have splendid prevention effect.
In soybean biological yield in performance, using the fomesafen aqua product containing glycine and glycine is free of
Product contrast, resistance of the soybean in growth course significantly improves, and final soybean yields has 5 ~ 10% volume increase effect
Fruit.
Embodiment
Prepare example one：
25% fomesafen aqua
255 grams of fomesafen active compounds are added in 2000ml flat bottom beaker, 440 grams of deionized waters, open stirring, Ran Houhuan
It is slow to instill 80 grams of 30% sodium hydroxide, continue stirring more than 10 minutes after being added dropwise, make fomesafen active compound and sodium hydroxide
Fully reaction neutralizes complete, forms clear solution, is eventually adding 200 grams of APG class surfactant adjuvant, glycine 25
Gram stir to clarify it is transparent after obtain 1000 gram of 25% synergy fomesafen sodium salt aqua product.
Prepare example two：
37.5% fomesafen aqua
385 grams of fomesafen active compounds are added in 2000ml flat bottom beaker, 245 grams of deionized waters, open stirring, Ran Houhuan
It is slow to instill 120 grams of 30% sodium hydroxide, continue stirring more than 10 minutes after being added dropwise, make fomesafen active compound and hydroxide
Sodium fully reacts neutralization completely, forms clear solution, is eventually adding 200 grams of APG class surfactant adjuvant, glycine
50 grams, be slightly warming up to 60 degree, stir to clarify it is transparent after be cooled to room temperature and obtain 1000 gram of 37.5% synergy fomesafen sodium
Salt aqua.
Its preventive effect to anti-bitterroot can reach 90%-92% after the aqua that above-mentioned two embodiment obtains, if increase Soviet Union ammonia
It is sour then 92-95% can be reached to the preventive effect of anti-bitterroot, if 93- can be reached to the preventive effect of anti-bitterroot by being further added by glutamine
98%。
