Abstract
The herbicide consists of 2- 4-(6-chloro-2-quinoxaloxy)phenoxy]-ethyl propionate and synergistic aid GAE. Tests verified that it had synergistic effect for preventing and killing weeds of the grass family, the amount of effective component of the herbicide applied per unit area reduced by 50%, and the cost reduced by about 37%.
Description
The present invention relates to pesticide field, is a kind of combination and production method thereof of weed killer herbicide specifically, international Patent classificating number A01N.
Existing technology proves, 2-[-4-(6-chloro-2-quinoxaline oxygen base] ethyl propionate [quizalofop-ethyl (quizalofop-P-ethyl)] is a kind of grassy weed to be had the weed killer herbicide of good preventive effect, but it costs an arm and a leg, and use cost is higher.
Therefore improve the result of use of this medicine, reduce usage amount and have very big meaning.Manufacturer points out, add the oil of non-ionic surface active agent NIPPOLO.15～3% or 100 times, can improve the effect of agricultural chemicals, but general increase rate is 10～20%, because this analog assistant usage amount is bigger, be not easy to allocate into and form single formulation in the agricultural chemicals, thus in use inconvenient, and also use cost can not significantly be reduced.
The objective of the invention is to utilize quizalofop-ethyl to be effective ingredient, be mixed with a kind of new composition, said composition can improve the control efficiency of quizalofop-ethyl to weeds significantly.
Main contents of the present invention below are described in detail in detail.
Composition of the present invention is mainly by 2-[-4-(6-chloro-2-quinoxaline oxygen base] ethyl propionate [quizalofop-ethyl (quizalofop-P-ethyl)] and builder GAE(GAE trade name extensively imitate liquid, produce by Chengdu, Sichuan fine chemistry industry Applied Research Laboratory) and emulsifier, solvent composition accordingly.
The detailed prescription following (percentage by weight) that dogstail of the present invention is excellent:
Quizalofop-ethyl 3-10%
GAE 5-20%
Emulsifier 10-20%
Solvent 50-80%
Stabilizing agent 0.5-5%
Emulsifier in this composition can be any a pair of among agricultural newborn 657H and 657L, 656H and 656L, peaceful newborn 353H and the 353L.Solvent can be ortho-chlorotolu'ene, C9～C11 aromatic hydrocarbons or their mixture, and stabilizing agent can be a phenol.
Fig. 1 is a process chart of the present invention.
Special addition agent GAE can improve quizalofop-ethyl EC to the prevention effect of weeds, and is when the addition of GAE is 5% when above of whole amount of formulation, although the dosage of unit are has reduced half, still suitable with normal consumption to the preventive effect of weeds. Thereby reduced the use amount of agricultural chemicals, reduced environmental pollution. Because the price of 5% GAE is lower than the price of second half quizalofop-ethyl, therefore, after using GAE, reduced significantly the use cost of unit are.
It below is result of the test
Guangxi 1995
Prevent and kill off 20 days effect fresh weights of Citrus Orchard grassy weed preventive effect % strain and count preventive effect %
5% quizalofop-ethyl EC 50ml/ mu 93.2 86.5
The excellent 27.5ml/ mu 92.3 83.8 of dogstail
Below be described in detail embodiments of the invention, but the invention is not restricted to this example.
Get 1 kilogram of the former medicine of quizalofop-ethyl, add 5 kilograms of ortho-chlorotolu'enes, 4 kilograms of C9～C11 aromatic hydrocarbons, the 657H0.6 kilogram, the 657L1.4 kilogram, the GAE1.2 kilogram, 0.12 kilogram of phenol fully stirs evenly mixedly by accompanying drawing 1 described technology, and it is excellent promptly to get present composition dogstail.
The present invention has following positive effect:
1, decrease the unit are use amount of agricultural chemicals, every mu agricultural chemicals use amount can reduce by 50%, thereby use cost also can correspondingly reduce, thereby can save a large amount of foreign exchanges for country.
2, because the reduction of amount of application, thereby reduced the pollution of agricultural chemicals to environment.
3, builder need not now to mix existing usefulness, has allocated in advance in the agricultural chemicals, uses more convenient.
