Abstract
The invention discloses a weeding composition containing oxaziclomefone and mesotrione. The effective constituents are oxaziclomefone and mesotrione, and the rest are pesticide adjuvants. The mass fraction ratio of oxaziclomefone to mesotrione in the weeding composition is 1:30-30:1. The weeding composition can be prepared into suspending agents, oil suspending agents, wettable powder or water dispersible granules according to the application needs to prevent and kill off annual weeds in paddy fields. The composition is much better than single oxaziclomefone or mesotrione in preventing and killing off weeds in paddy fields, the dosage can be reduced, and the drug resistance of weeds can be postponed.
Description
Technical field
The present invention relates to a kind of agricultural chemicals Herbicidal combinations, Shi Yi oxazine humulone and nitre sulphur humulone are active ingredient, are used for control paddy field annual weed.
Background technology
The chemical method weeding is that agricultural goes up one of main means of controlling weeds.In recent years, because some weed killer herbicide kind large tracts of land are used separately, caused a lot of weeds to develop immunity to drugs.Simultaneously, the grass when weeds are taken place is complicated mutually, and grassy weed, broad leaved weed, nutgrass flatsedge multiclass weeds mix and give birth to, and the single variety weed killer herbicide uses can not solve farmland weed, all can show in a certain respect defective and limitation.The variety classes weed killer herbicide is mixed, have herbicidal spectrum wide, promote actual effect, delay the weeds pesticide resistance, the time and labour saving advantage.
The oxazine humulone has another name called the barnyard grass peace, english common name: oxaziclomefone, and structural formula:
The oxazine humulone belongs to the organic heterocyclic class, is the inner sucting conduction type herbicide for paddy field, and mainly root and the cauline leaf base portion by weeds absorbs.Leaves and stems chlorosis behind the weeds contacts medicament, stop growing, until withered.
Nitre sulphur humulone, english common name: mesotrione, structural formula:
Nitre sulphur humulone suppresses the activity of PHPPA dioxygenase (HPPD), and HPPD can be converted into plastoquinone with amino acid Lip river propylhomoserin.Plastoquinone is the co-factor of phytoene desaturase.It is the biosynthetic key enzyme of carotenoid.Use 3-5 days implants meristematic tissue of mesotrione the yellow symptom to occur and cause withered spot thereupon, spread all over whole strain plant behind the fortnight.Have faintly acid, in the inoic acid soil, can tightly be adsorbed on the organic substance; In neutrality or basic soil, exist to be difficult for absorbed anionic form.
The variety classes weed killer herbicide is mixed, have herbicidal spectrum wide, promote actual effect, delay the weeds pesticide resistance, the time and labour saving advantage.By the formulation of pesticide screening, can effectively improve actual control efficiency, reduce dosage, reduce cost, delay disease, worm, the drug-fast generation of crop smothering, be the important means that agricultural synthesis is administered.Further investigation Fa Xian oxazine humulone has been carried out in the prescription screening of inventor's paroxazine humulone and nitre sulphur humulone and nitre sulphur humulone is mixed, in certain mixed ratio scope the paddy field annual weed there are synergy or summation action, after further study, have finished the present invention.
Summary of the invention
The objective of the invention is to solve in the prior art develop immunity to drugs problem and actual control efficiency of farmland weed relatively poorly, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, is conducive to the composition pesticide of the farmland weed comprehensive regulation.
Technical scheme: for achieving the above object, the invention provides the Herbicidal combinations of a kind of Han You oxazine humulone and nitre sulphur humulone, the ratio of quality and the number of copies of active ingredient Wei oxazine humulone and nitre sulphur humulone ， oxazine humulone and nitre sulphur humulone is 1:30～30:1.
Herbicidal combinations of the present invention is prepared into known method and is fit to any one formulation that agricultural goes up use, and reasonable formulation has suspending agent, oil-suspending agent, wetting powder or water dispersible granules.
Herbicidal combinations provided by the invention adopts usually and converts the use of water spray method, also can adopt agricultural to go up other operation techniques of using as required.
Herbicidal combinations provided by the invention in use should be to the shooting stage behind rice seedling, and paddy field annual weed 5 leaves used before the phase.
Beneficial effect: the paddy field weed effect of preventing and kill off of the present invention obviously is better than each single agent, reduces dosage, delays the weeds pesticide resistance.
Technology of the present invention source: for further Xie oxazine humulone and nitre sulphur humulone are mixed to the synergy of weeds, inventor's paroxazine humulone and nitre sulphur humulone are mixed and have carried out formulation screening test.
Test material:
Monochoria vaginalis [
Monochoria vaginalis] (field is collected seed and preserved);
The barnyard grass grass [
Echinochloa crusgalli(L.) Beaw Setaria] (field is collected seed and is preserved).
Test apparatus: controlled illumination box; POTTER exact test chamber spray tower; Electronic balance (sensibility reciprocal 0.1mg); Micropipette rifle etc.
Test method: the purity that takes by weighing certain mass earlier is the former medicine of 96.5% oxazine humulone, purity is the former medicine of 95% nitre sulphur humulone, the Tween 80 aqueous solution with 0.1% after adding acetone fully dissolves dilutes, be mixed with single agent mother liquor respectively, according to the purpose that is mixed serial proportioning is set, each proportioning arranges 5～7 concentration gradients.Kill the grass spectrum according to single agent and select representative susceptible weeds seed, it is standby to be cultured to the dew bud.After the weeds cauline leaf of selecting numbering handled, be placed in the illumination box incubated at room temperature 20 days, calculate control efficiency (fresh weight), then with method of least squares calculate suppress in dense EC
50(95% confidence limit) calculates co-toxicity coefficient (CTC) with the abundant method of Sun Yun again.
Co-toxicity coefficient (CTC) 〉=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80＜co-toxicity coefficient (CTC)＜120 shows as summation action.
Actual measurement toxicity index (ATI)=(standard medicament EC
50/ reagent agent EC
50) * 100.
Theoretical toxicity index (TTI)=(percentage composition of A in toxicity index * mixture of A)+(percentage composition of B in toxicity index * mixture of B).
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (the ATI)/theoretical toxicity index (TTI) of mixture] * 100.
Measurement result show (see Table 1 and table 2) ， oxazine humulone and nitre sulphur humulone between mixed ratio 1:30～30:1, have obvious synergistic effect.
Table 1, different Pei measure the synergy of Monochoria vaginalis Bi oxazine humulone and nitre sulphur humulone.
Table 2, different Pei measure the synergy of barnyard grass grass Bi oxazine humulone and nitre sulphur humulone.
