Description
Technical field
The present invention relates to technical field of pesticide, and in particular, to a kind of composition pesticide and its application.
Background technology
Paddy field weed and rice strive ground, strive fertilizer, win honour for, strive water, seriously affect the yield and quality of rice, according to surveying and determination,
Rice will generally reduce income 10% or so because of crop smothering every year, and is more than 50% more.Weeds can also induce pest and disease damage, have plenty of more
The vector of kind disease pest.
The use of paddy chemical weeding agent is nearly 30 years emerging technologies to grow up in China, and not only effect is good for it, goes out
It is careless to be conducive to full stand, strong sprout in time, and saving of labor, save fertilizer, increase production, increase income, labor intensity is also greatly reduced, large quantities of labor are liberated
Power marches the condition of providing for depth from peasant to agricultural production and range.However herbicide for paddy field popularization and application are also brought
Some negative effects.First, some places use always the herbicide of sulfonylurea for many years, resistance is generated；Second is that Seedling Stage
Using or overdose use or not by regulation technology requirements application or misuse cause poisoning.Therefore, paddy field chemical herbicide is applied
It is scientific with having to, different paddy field weeds is had to select suitable herbicide kind, optimum period, appropriate application.
How to develop a kind of can effectively prevent the composition pesticide that rice weed, drug resistance are good and environmental pollution is small and be
A technical problem to be solved urgently.

Test case 1
The composition pesticide of testing example 1-15 and comparative example 1-9 is to the control effects of weeds in Rice Cropping field,
Specific steps include：After transplanting rice 6 days, in different growing area internal sprayings removing using embodiment 1-15 and comparative example 1-9
Careless agent composition.The amount of application of composition pesticide is 100g/ mus, and the area for testing the growing area of each composition pesticide is
50 ㎡, when application, is diluted with water 3000 times, and substitutes composition pesticide using water and be used as space management, except by said program using agriculture
Outside drug composition, other planting conditions of each growing area are identical.After spreading fertilizer over the fields composition pesticide 30 days, to the weeds of growing area
Counting is identified, calculates strain preventive effect by formula (A), the results are shown in Table 1.
Table 1
Note：Blank control group provides reference data for each treatment region, therefore without control effect data.
As it can be seen from table 1 the composition pesticide of the present invention is the scheme compounded using two kinds of active components, life
Object activity with control effect be not each component it is active it is simple be added, it is significant anti-except having relative to the preparation of single component
It controls outside effect, also has significant synergies.Therefore dosage can be reduced, reduces cost, mitigate pesticide residue to environment
Pollution.Two kinds of active components in the composition pesticide of the present invention are applied in combination according to special ratios simultaneously, can be to a variety of fields
Between weeds be carried out at the same time prevention, relative to oligomict pyraclonil, alachlor, propisochlor, isopropyl methoxalamine, smart isopropyl first
Careless amine, kecaoan, propachlor can obtain the effect of notable synergistic, and dosage is low, both delay the development of weed resistance
It is again cost-effective.The composition pesticide of the present invention is suitable for the prevention of rice field weeds, and safety is good, to the guarantor of ecological environment
Shield plays positive effect.
Embodiment 1-15 is compared as can be seen that the weight ratio of the first active component and the second active component is 1：
(0.02-30), the especially weight ratio of the first active component and the second active component are 1：When (0.1-10), it can further improve
Control effect.Specifically, in Examples 1 and 2 the weight ratio of two kinds of active components most preferred 1：In (0.1-10) range, and
And the dosage form of preparation is preferred suspension emulsion, and it is added to antidrift agent, various components and proportioning meet " 2.5-30 in preparation
The first active components of weight %, the second active components of 0.5-25 weight %, 3-15 weight % emulsifiers, 2-5 weight % dispersants,
0.1-5 weight % thickeners, 0.1-8 weight % antifreezing agents, 0-50 weight % solvents, 0.2-1 weight % antifoaming agent, 0.1-1 weights
Measure % antidrift agents and the water of surplus ", therefore, preparation is optimal to the control effect data of multiple diseases in Examples 1 and 2；
The weight ratio of two kinds of active components is most preferred 1 in embodiment 3-7 preparations：In (0.1-10) range, and the dosage form of preparation
It is preferred suspension emulsion, embodiment 3-7 preparations are more excellent to the control effect data of multiple diseases；Two in embodiment 8 and 9 preparations
The weight ratio of kind active component is 1：In (0.1-10) range, but the dosage form of preparation is respectively wettable powder and dispersible oil
Suspending agent, compared with the control effect data of embodiment 3-7 preparations, the control effect of embodiment 8 and 9 preparations is slightly taken second place；Implement
The weight ratio of two kinds of active components is in more excellent range 1 in 10 preparation of example：In (0.02-30), and preparation formulation is suspension emulsion, is implemented
The control effect data of 10 preparation of example are slightly inferior to embodiment 8 and 9；The weight ratio of two kinds of active components in embodiment 11-13 preparations
In more excellent range 1：In (0.02-30), the dosage form of preparation respectively is microemulsion, microcapsule suspension-suspendinagent agent and missible oil, therefore
The control effect data of embodiment 11-13 preparations are worse than embodiment 10；Embodiment 14 and 15 weight of formulation ratio are in general range 1：
In (0.01-90), and dosage form is not preferred dosage form, and embodiment 14, the control effect data of 15 preparations are inferior to embodiment 11-13.
On the one hand, the preparation of composition pesticide of the invention relative to single component has synergistic effect, prevention can be improved
Effect；A variety of different types of diseases that mixing can effectively be prevented or occurred in succession improve crops to be reduced using pesticide
Health, it is cost-effective, mitigate the pollution to environment.On the other hand, pesticide group that more active components compounds is not it
Conjunction object is better to the control effect of crop disease, by comparative example 9 as can be seen that excessive active component compounding does not carry not only
The control effect of high pesticide limits the synergistic function between different activities component to a certain extent instead；Numerous energy
Enough in the active component of prevention crop disease, it can be compounded between matched active component and between each other can be synergistic,
Unmatched active component compounding is unfavorable for the performance of its effect instead, present inventor by thousands of experiments just from
Selected in numerous active components with each other can matched active component and determine compounding active component type
Weight ratio between quantity and active component, therefore the composition pesticide could have disease the control effect being obviously improved.
The preferred embodiment of the present invention has been described above in detail, still, during present invention is not limited to the embodiments described above
Detail can carry out a variety of simple variants to technical scheme of the present invention within the scope of the technical concept of the present invention, this
A little simple variants all belong to the scope of protection of the present invention.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the present invention to it is various can
The combination of energy no longer separately illustrates.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
The thought of invention, it should also be regarded as the disclosure of the present invention.
