Abstract
The present invention relates to a kind of Herbicidal combinations for preventing and treating weeds of wheat, active constituent is quinoline humulone and ethoxyfen-ethyl, and the weight ratio of quinoline humulone and ethoxyfen-ethyl is 10:1 ~ 1:5.Pharmacodynamic test shows that the composition has the characteristics that with strong complementarity, synergistic effect is obvious, amount of application is reduced, high, environmental pollution reduces, is strong with environment compatibility to crop safety.
Description
Technical field
The present invention relates to plant protection composition technical fields, specifically, being a kind of weeding for preventing and treating weeds of wheat
Composition.
Background technique
Quinoline humulone, a kind of HPPD inhibitor, broad weed-killing spectrum is efficient to a variety of broadleaf weeds and gramineae weed, to dog tail
Careless preventive effect is brilliant, and quick-acting is good.
Ethoxyfen-ethyl, a kind of diphenyl ether herbicide, be mainly used for seedling rear defence except soybean, wheat, barley, peanut,
Broadleaf weeds in the crop fields such as pea, such as more than ten kinds of weeds of piemarker, redroot amaranth, clearvers, Siberian cocklebur.
Summary of the invention
The purpose of the present invention is aiming at the shortcomings in the prior art, provide a kind of Herbicidal combination for preventing and treating weeds of wheat
Object.
To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of prevent and treat weeds of wheat Herbicidal combinations,
Its active constituent is quinoline humulone and ethoxyfen-ethyl, and the weight ratio of quinoline humulone and ethoxyfen-ethyl is 10:1 ~ 1:5.
The invention has the advantages that:
Two kinds of active components show as synergistic effect in composition of the invention, and the activity of the composition is than using single compound
The expected summation of activity and single compound independent activity it is more significant.The composition has with strong complementarity, synergistic effect
Obviously, the features such as amount of application is reduced, high, environmental pollution reduces, is strong with environment compatibility to crop safety.
Specific embodiment
It elaborates below with reference to embodiment to specific embodiment provided by the invention.
Embodiment 1
Quinoline humulone 15%, ethoxyfen-ethyl 5%, sodium methylene bis-naphthalene sulfonate 7%, calcium lignosulfonate 5%, kaolin complements to
100%.It is uniformly mixed entering in mixer after above-mentioned formula in proportion coarse crushing, obtains wettable after the airflow crushes
Pulvis.
Embodiment 2
Quinoline humulone, ethoxyfen-ethyl are processed into 20% wettable powder respectively, are administered according to the amount of 4g effective component per acre,
The mixture that different proportion is prepared in experimental design processing carries out field weeding test.
Each treatment region 30m2, it is administered in the weeds of wheat 2-3 leaf phase, each chemicals treatment is repeated 3 times.7 days after application,
15 days, the safety of 35 days investigation preventive effects and confection to wheat.
Using quinoline humulone as standard agent, disease index and control efficiency are calculated.Control efficiency is converted into probability value
(y), liquor strength (μ g/ml) is converted into logarithm (x), calculates concentration EC50 in virulence equation and inhibition with least square method,
The toxicity index grade co-toxicity coefficient (CTC) of medicament is calculated according to Sun Yunpei's Method.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
B in the percentage composition+B medicament toxicity index * mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixture
Percentage composition
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] * 100
CTC≤80, composition show as antagonism, 80 < CTC < 120, and composition shows as summation action, CTC >=120,
Composition shows as synergistic effect.
35 days Herbicidal Testing Trials results after 1 medicine of table
| Medicament | EC50(μg/ml) | ATI | TTI | CTC |
| A | 0.47 | 100.00 | / | / |
| B | 6.49 | 7.24 | / | / |
| A:B=10:1 | 0.41 | 114.63 | 91.57 | 125.19 |
| A:B =5:1 | 0.37 | 127.03 | 84.54 | 150.26 |
| A:B =3:1 | 0.35 | 134.29 | 76.81 | 174.83 |
| A:B =1:1 | 0.54 | 87.04 | 53.62 | 162.32 |
| A:B =1:3 | 1.05 | 44.76 | 30.43 | 147.09 |
| A:B =1:5 | 1.59 | 29.56 | 22.70 | 130.21 |
In table, A refers to that quinoline humulone, B refer to ethoxyfen-ethyl.
The result shows that quinoline humulone and ethoxyfen-ethyl be between proportion 10:1 ~ 1:5, co-toxicity coefficient 120 or more,
Illustrate that quinoline humulone compounds preventing and kill off with significant synergistic function to weeds of wheat with ethoxyfen-ethyl.
Embodiment 3
Quinoline humulone 15%, ethoxyfen-ethyl 5%, lauryl sodium sulfate 3%, polyvinyl alcohol 1%, white carbon black 20%, kaolin is supplied
To 100%.It is granulated after weighing each component progress ultra-fine grinding by formula, is dry, sieved up to water-dispersible granules.The water dispersion
Property granula for preventing and kill off wheat paddock annual gramineous weed, mu is with 30 grams, weeds 2-3 leaf phase spraying treatment, prevents within 10 days after medicine
Effect is 98.5%.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, under the premise of not departing from the method for the present invention, can also make several improvement and supplement, these are improved and supplement also should be regarded as
Protection scope of the present invention.
