Description
Technical field
The present invention relates to a kind of pesticide herbicide fields, and in particular to a kind of weeding containing AC 263222 and prometryn
Composition and its application.
Background technology
Peanut is the main oil crops in China, in recent years, long-term cultivated area at 70,000,000 mu or so, with Henan,
Shandong, Hebei, Anhui are major production areas.China's Weed in peanut field occurrence quantity is big and type is various, seriously affects the yield of peanut
And quality.According to incompletely statistics, peanut because weeds caused by the underproduction in 6%-15%, serious plot may be up to 50% with
On.
AC 263222 (imazapic) is a kind of imidazolone type wide spectrum, ultra high efficiency Peanut Fields herbicides special, is inhibited
Weeds acetolactate synthestase prevents branched-chain amino acid from synthesizing, and in turn results in weeds death.Prevent and kill off annual and perennial grass
Section weeds and broad leaved weed, to rhizome of nutgrass flatsedge special efficacy.But it is longer that the ingredient imitates the phase in the soil, if dosage Gao Shiqi is in soil
In residual quantity be easy injury succession crop, cause the different degrees of underproduction.
Prometryn (prometryn) is a kind of inhibitor of photosynthesis, blocks electron transfer process in photosynthesis of plant,
In turn result in weeds death.Can be used for the crop fields such as paddy and wheat, cotton, peanut, soybean, vegetables, fruit tree prevent and kill off 1 year raw broad leaved weed,
Dogstail, nutgrass flatsedge and certain perennial weeds.
It is means the most economical and effective during farmland weed is prevented and kill off using herbicide chemical weed control.But long-term continuous high agent
The problems such as using to amount single variety or the chemical herbicide of the single mode of action, be easy to causeing weeds drug resistance and resistance evolution.
The reasonable compounding or mixture of herbicidal compounds, which have, to be expanded weeds spectrum, improves preventive effect, delays weeds drug resistance and anti-medicine
The advantages that generation and development of property, be one of the most effective methods to solve the above problems.

The above-mentioned Herbicidal synergistic wettable powder containing AC 263222 and prometryn is in preventing Peanut Fields injurious weed
Application.
On the basis of said program, the Peanut Fields injurious weed is lady's-grass, barnyard grass, lamb's-quarters, purslane.
Beneficial effects of the present invention：Present invention is mainly used for soil treatments, have significant synergies, and can effectively prevent
Peanut Fields major part weeds are controlled, safety is good, and reduces the security risk to succession crop.
Specific implementation mode
Term as used in the present invention generally has those of ordinary skill in the art usual unless otherwise specified
The meaning of understanding.
With reference to specific embodiment, and with reference to the data further detailed description present invention.Following embodiment only be
It illustrates the present invention, rather than limits the scope of the invention in any way.
Embodiment
One, indoor proportioning joint toxicity measuring
For trying weeds：Lady's-grass (Digitaria sanguinalis), barnyard grass (Echinochloa crusgalli), lamb's-quarters
(Chenopodium album), purslane (Portulaca oleracea).
Experimental condition and the culture for trying material：The culture of experiment examination material, 25~35 DEG C of temperature are carried out in illumination cultivation room.It will
Quantitative lady's-grass, barnyard grass, lamb's-quarters, purslane presprouting of seeds are sowed at after showing money or valuables one carries unintentionally in the plastic tub of diameter 8cm, and 1~2mm of earthing is put into
In pallet equipped with water, water is allowed gradually to penetrate into, it is for use that illumination cultivation room is transferred to after waiting water to be seeped into native table.
Reagent agent：98% AC 263222 active compound, Weifang CYNDA Chemical Engineering Co., Ltd provide；95% prometryn active compound,
Shandong Weifang Rainbow Chemical Co., Ltd. provides.
Reagent agent drug solution preparing：Weigh quantitative AC 263222 and prometryn active compound, diformazan respectively with electronic balance
Base formamide (DMF) dissolves, and required concentration is diluted to 0.1% Tween-80 aqueous solution.
Test dose designs：
1 reagent agent management of weeds test dose of table designs (dosage g.a.i./hm2)
Application method：Test in weed seed show money or valuables one carries unintentionally after planting soil even spraying processing.Weeds are uniformly placed in face
Product 1m2Platform on, with ASS-4 type automatic rations spraying system (National agricultural information project Technical Research Center) spray,
Teejet9503EVS Fan spray heads, spouting liquid 450L/hm2, atomisation pressure 0.275MPa, 4 repetitions.
Weedy rices method, time：It weighs each processing weeds aerial part fresh weight within 20 days after dispenser, calculates fresh weight preventive effect.
Drug effect computational methods：Theoretical fresh weight inhibition rate (the E of each processing blend compositions is calculated with Gowing methods0=X+Y-
X*Y/100), then compared with actual measurement inhibiting rate (E), the mixed synergy type to weeds of both evaluations works as E-E0Value
It is synergistic effect more than 10%, be antagonism less than -10%, is addition between -10%~10%.
2 AC 263222 of table is mixed with prometryn to grassy weed control effect
3 AC 263222 of table is mixed with prometryn to broad leaved weed control effect
By composition provided by the invention it can be seen from upper table 2,3 to grass family and broad-leaved under suitably proportioning dosage
Weeds have outstanding preventive effect, and can significantly improve preventive effect of the AC 263222 to lamb's-quarters, and synergistic effect is apparent.
Peanut Fields major part weeds still can be prevented and kill off in the case that reducing AC 263222 dosage, and reduce the safety to succession crop
Risk.
Two, field control effectiveness test：
Each ingredient of each composition and content according to the form below correct amount obtain composition wettable powder through Ultrafine Jet Milling
Agent 1~6, is shown in Table 4.Comparison medicament is：240g/L AC 263222s aqua (German BASF), 40% prometryn wettable powder
(Zhejiang Zhong Shan chemical industry).Soil moisture is moderate, and soil moisture content is good, and soil treatment, spouting liquid 450L/ are immediately carried out after peanut seeding
hm2.Fresh weight preventive effect is investigated after 40 days.

5 each composition field efficacy of table
Field control effectiveness test shows that AC 263222 is mixed with prometryn under less than crop field recommended dose and can get well
Herbicidal effect, half measures the AC 263222 integrated control effect to weeds mixed with constant prometryn up to 93%, and grass is flutterred with partly measuring
Only mixed preventive effect is also 82% or more.The low dosage of AC 263222 is applied, and the residual risk to second stubble crop can be reduced.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But it is every without departing from technical solution of the present invention content, according to the technical essence of the invention to above example institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection domain of technical solution of the present invention.
