Description
Technical field
The present invention relates to a kind of Herbicidal combinations, particularly relate to a kind of binary built, be applied to the Herbicidal combinations in Semen Maydis field.
Background technology
In plant husbandry, preventing and treating suppression plant growth to cause weeds that yield reduces and cover crop be critically important.In order to reduce the loss caused due to the weeds in arable farming, as growth difference or crop yield reduce, have now been developed that some can effectively prevent and treat described weeds and the herbicidal active component to crop safety.Up to the present, there is the herbicide developed in a large number registered and for preventing and treating the weeds of some crop.Sufficiently high activity of weeding and a broad herbicidal spectrum should be had for preventing and treating the herbicide of the weeds in specific arable farming, and response environment and crop safe enough.But, not every herbicide can fully meet above-mentioned requirements.
Most-often used increase activity of weeding is that two or more have the herbicidal active compounds mixing of different activity of weeding with the method for the herbicidal spectrum widening existing herbicide.If mixing two or more herbicidal active compounds, the herbicide action outstanding than single herbicide application may be demonstrated.When the effect of the mixture of two or more composition is more than the expection effort levels of each composition, we term it " potentiation ".But, present in the Herbicidal mixture of the two or multiple herbicidal active compounds, potentiation is the most visible.Due to the difference of the aspects such as herbicidal performance, absorbance, transfer, metabolism, the activity of weeding of most of mixture is singly executed less than each composition." antagonism " represents the such situation i.e. herbicide action of the mixture of two or more herbicidal active compounds singly executing less than each composition." addition " represents that the such situation i.e. herbicide action of the mixture of two or more herbicidal active compounds is identical with singly executing of each composition.
Topramezone, English common name Topramezone, chemical name [3-(4,5-dihydro-3-isoxazolyl)-4-sulfonyloxy methyl-2-methylbenzene] 5-hydroxyl-1-methyl isophthalic acid H-pyrazoles-4-base) ketone, its chemical structural formula is:

Biological Examples
Evaluation to the mixed potentiation executing middle display of two or more herbicidal active component is based on " CalculationSynergistic
And Antagonistic Response of Herbicide Combinations " Colby ' s method described in (Weeds 15/1 (1967), S.R.Colby) determines.
Shown in computing formula such as following formula (1)
……………………………………(1)
In formula (1), X represents herbicide A control of weeds (%) under Xg effective ingredient/ha consumption,
Y represents herbicide B control of weeds (%) under Yg effective ingredient/ha consumption,
E0Represent the expection control of weeds (%) under X+Yg effective ingredient/ha consumption.
If the actual control of weeds rate observed in biologic test exceedes use Colby ' s method calculated desired value (E0), then it represents that the effect of Herbicidal combinations is more than the summation of each agent effectiveness, it means that compositions has potentiation.
Test before Seedling:
Under greenhouse experiment, unifacial leaf and the seed of dicots ruderal plant or rhizome are placed in equipped with covering in the alms bowl of dauk and with soil.Use standard soil as cultivation matrix.In the Seedling last stage, herbicide individually or is as a mixture administered to soil surface.After process, alms bowl is placed in greenhouse and is held under the excellent growing conditions being suitable to weeds.By compared with untreated matched group, the infringement of emerging after emerging the plant damage after the test period in 3-4 week or test plants carries out visual assessment.Shown in test result, the Herbicidal combinations of the present invention illustrates the best activity of weeding before emerging to broad-spectrum weeding.Testing viewed numerical value to show, under suitable low dosage, the effect of Herbicidal combinations of the present invention has exceeded the desired value according to Colby, shows obvious potentiation.
Test after Seedling
As long as the effect of the combination of topramezone and rimsulfuron is more than the summation of effect when each active component is used respectively, exist for potentiation.
Use potted plant stem and leaf facture (NY/T 1155.4-2006): the built-in quantitative soil of polypots at high 6cm, diameter 9cm, 15 ~ 20, the seed of unifacial leaf and dicots weeds is sowed in polypots, temperature indoor cultivation it is placed on after the fine earth that lid 0.5 ~ 1cm is thick, treat that weeds length carries out stem and leaf spraying treatment to 2 ~ 4 leaf phases, every alms bowl spraying liquid 1mL, often process and be repeated 4 times, and set the process without medicament as compareing.Process is placed on temperature indoor cultivation, the growing state of routine observation target weeds, estimates target damage symptoms and growth inhibited situation, and claims aerial parts fresh weight or strain fresh weight, evaluate the medicament toxicity action to target weeds with target fresh weight inhibition after 21d.
According to constant weight percentage ratio three kinds of reagent of preparation: 1, topramezone；2, rimsulfuron；3, topramezone+rimsulfuron；Afterwards by above-mentioned each reagent dilute with water, it is thus achieved that medicament diluent.
Investigation method:
Test estimates target damage symptoms and growth inhibited situation after processing 21d, and claims aerial parts fresh weight, calculates fresh weight inhibition (%).
Evaluation to the mixed potentiation executing middle display of two or more herbicidal active component is based on " CalculationSynergistic and
Antagonistic Response of Herbicide Combinations”(Weeds
15/1 (1967), S.R.Colby) described in Colby ' s method determine.
In formula, X is topramezone with certain dosage fresh weight inhibition to target weeds time alone；
Y is rimsulfuron with certain dosage fresh weight inhibition to target weeds time alone；
E0For theoretical value to target weeds fresh weight inhibition when topramezone and two kinds of pharmacy mix of rimsulfuron；
E is topramezone and measured value to target weeds fresh weight inhibition during two kinds of pharmacy mix of rimsulfuron.
If the actual control of weeds rate observed in biologic test exceedes use Colby ' s method calculated desired value (E0), then it represents that the effect of Herbicidal combinations is more than the summation of each agent effectiveness, it means that compositions has potentiation.
Table 1: containing topramezone and the postemergence weed control effect of the present composition of rimsulfuron when 21 days after dispenser:
As can be seen from the above table: when the proportioning of topramezone and rimsulfuron is in the range of 50:1-1:50, reveal gain effect, especially when its proportioning
Time in 24:1-1:4, gain effect is the most prominent.
