Description
Technical field
The invention belongs to technical field of pesticide, a kind of with being related to potato weeding agricultural chemical compositions.
Background technology
Green bristlegrass bar grass, alias green bristlegrass, category grass family, setaria annual herb plant.Root is palpus shape, tall and big plant
Strain tool supports root.Stalk is upright or base portion knee is bent, high 10-100 centimetres, and base portion footpath reaches 3-7 millimeters.Leaf sheath relaxes, hairless
Or tool pubescence or wart hair are dredged, edge has longer close wool shape cilium.It is born in the wilderness below 4000 meters of height above sea level, by road,
For a kind of weeds that dry crop is common.
Lamb's-quarters, annual herb, avette to the wide lanceolar of blade water chestnut shape, how rare white powder below, edge has irregular sawtooth；
Petiole is closely isometric with blade, or is the half of length of blade.Flower both sexes, flowers are arranged in either large or small spike in branch top
Coniform or circular cone locusta, pericarp and seed adhesion, seed grow wild, lenticular.The flowering fruit bearing stage 3-6 months.Lamb's-quarters is 1 year
Sward sheet, early spring sprouts, 3~May of florescence, 4~June of fruiting period.Seminal propagation.Suitable moistening of being born in has slight saline and alkaline
Sand loam on.
Wild oat, wild oat is annual herb plant.It is the weeds of the crops such as wheat class of causing harm.Also known as small bell wheat.Plant height
30-150 centimetres.Fibrous root；Stem is grown thickly；Leaf sheath relaxes, and the tip of a leaf is big and transparent；Panicle；Caryopsis spindle.Viability
By force, humidity is liked, mostly occurs in arable land, irrigation canals and ditches side and roadside, is the Associated weeds of wheat.Due to contention fertilizer, water, illumination,
Cause covering to cover, often cause wheat early lodging or undergrowth.Control measures include setting up seed-breeding field, carry out floods and droughts wheel
Make, lie fallow and lie prostrate and turn over weed eradication.Wheatland, which can apply oat, to be feared or is sprayed with diclofop-methyl, difenzoquat etc. in seedling stage, soybean and rape
Field can be with being sprayed in seedling stage more than withered grass.
In recent years, with the large-scale popularization of potato, obstinate weeds turn into the principal element of influence potato yield, especially
Wherein broad-leaved class and grassy weed, otherwise the big harm soil safety of commercial herbicide consumption, otherwise herbicidal effect is undesirable very
To invalid reduction harvest.
The content of the invention
It is an object of the invention to a kind of with inventing potato weeding agricultural chemical compositions, make its to potato weeds have height

Certain fineness is crushed to, then by being mixed into product, 21% quizalofopPtefuryl rimsulfuron wettable powder.
Embodiment 6：Preparation stability is tested
The formula design of the invention more than prepares corresponding experimental pharmacy and carries out cold and hot storage experiment, experimental result such as following table respectively：
Table one：It is as follows that 5 embodiments of the above carry out hot storage (54 ± 2 DEG C) situation
Application Example two：Field efficacy
Experiment observed weeds death condition while the various preparation activity of weeding of comparison after 20 days, 40 days respectively.Applying
Whether observation preparation produces poisoning to crop in 2 weeks after medicine.
Experimental group medicament is the corresponding medicament in embodiment 1-5；Treatment group 6 is：8% quizalofopPtefuryl missible oil, treatment group 7 is：
25% rimsulfuron oil-suspending agent, treatment group 8 is artificial weeding.
Result such as following table after implementing 20 days：
Result such as following table after implementing 40 days：
As can be seen from the above table the present invention to potato annual broad-leaved or/and grassy weed there is obvious imitation to act on, and
Monospecies preparation is substantially better than, with synergy substantially, the low feature of the long dosage of efficacy time.
Medicament is to crop safety investigation result：
By table it can be seen that 5 treated potato seedlings of embodiment grow fine, in the absence of dead seedling situation, and control group is tested
Seedling there is dead seedling situation.Illustrate binary built preparation of the present invention to potato safety, it is environmentally friendly.It is described above
It is only of the invention to be preferable to carry out case, do suitable under the premise of industry professional and technical personnel can not depart from the principle of the invention
When improving and soaking, these are improved and wetting is accordingly to be regarded as in protection scope of the present invention.
Embodiment eight：Indoor virulence test experiments, the joint toxicity measuring method of embodiment 1 to embodiment 5：
To further appreciate that Quizalotop-ethyl, rimsulfuron compound the synergy to weeds, the present inventor is sieved to formula
Choosing experiment, each proportioning sets 6-7 concentration gradient, and wild oat and lamb's-quarters are cultivated into standby to the 5-6 leaf phases, ASP-1098 is used
Type automatic sprayer empirically spray by design requirement cauline leaf, maintains greenhouse experiment, calculates and imitates after a week, then with most
Small square law calculates inhibition concentration EC50(95% confidential interval), and co-toxicity coefficient (CTC) is calculated by the abundant methods of Sun Yun, and by following
Formula is calculated：
ATI=(S/M) * 100
In formula：
ATI --- mixture surveys toxicity index；
The EC of S --- standard agent50, unit ug/ml；
M --- reagent agent EC50, unit ug/ml.
TTI=TIA*PA+TIB*PB
In formula：
TTI --- medicament theoretical toxicity index；
TIA--- A medicament theoretical toxicity index；
PA--- percentage composition of the A medicaments in mixture, unit is percentage；
TIB--- B medicament theoretical toxicity index；
PB--- percentage composition of the B medicaments in mixture, unit is percentage；
CTC=(ATI/TTI) * 100
In formula：
CTC --- co-toxicity coefficient；
ATI --- mixture surveys toxicity index；
TTI --- mixture theoretical toxicity index.
Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；CTC≤80 show as antagonism；The tables of 80 ＜ CTC ＜ 120
It is now summation action.
Table 1：Different ratio quizalofopPtefuryl rimsulfuron is to wild oat toxicity test result：
Table two：Different ratio quizalofopPtefuryl rimsulfuron is to lamb's-quarters toxicity test result：
By Tables 1 and 2 it can be seen that quizalofopPtefuryl and each ratio its co-toxicity coefficient of rimsulfuron compounding are above 120,
It is preferred that 1: 1 result, illustrates there is obvious synergistic effect after two kinds of composition compoundings, it can be seen that, both compound tool
There is very strong reasonability.
In summary result of the test can be seen that quizalofopPtefuryl and after rimsulfuron compounds by different proportion, not only to agriculture weeding
Prevention effect is significantly improved, and expands the scope of preventing and treating agricultural weed, in the case of prevention effect identical, is dropped significantly
The low usage amount of active ingredient, so as to reduce the harm to environment and delay resistance weed.
