Description
Technical field
The invention belongs to pesticide synergistic technical fields, and in particular to one kind includes polybenzobisoxazole humulone and picloram compound
Synergistic herbicide compositions.
Background technique
Wheat is important cereal crops in the world, belongs to grass family Triticum.Wheat is divided into spring wheat, winter according to sowing time
Wheat.Wheat is divided into rainfed wheat, Wheat after rice according to land occupation condition.China's Wheat Production is divided into 10 areas Ge great：Northeast spring wheat
Area, northern spring wheat area, Xi'an digital seismic network, the Xinjiang Winter-Spring area of wheat, Qinghai-Tibet spring Winter Wheat Area, Northern Winter area, varieties in Huang-Huai-Hai Plain, the Changjiang river
Middle and lower reaches Winter Wheat Area, southwestern Winter Wheat Area, south China Winter Wheat Area.In China, it is light that wheat also occupy act foot in the diet of people
The status of weight, it is the second largest cereal crops in China, thus people attach great importance to Wheat Production, using wheat as the north ground of staple food
Area is especially true.
At present weeds of wheat prevent and kill off in means the most economical and effective be using herbicide, chemical weed control is wheat paddock
Means the most economical and effective in weed control.But use single variety or the single mode of action to long-term continuous high dose
Chemical herbicide, the problems such as be easy to causeing weeds drug resistance and resistance evolution.The reasonable compounding or mixture of herbicidal compounds have
Expand weeds spectrum, improve preventive effect, delay the advantages that generation and development of weeds drug resistance and drug resistance, is to solve above-mentioned ask
One of the maximally efficient method of topic.
Summary of the invention
The problems such as to solve weeds drug resistance existing in the prior art and resistance evolution, the present invention provide a kind of comprising polybenzobisoxazole
The Synergistic herbicide compositions of humulone and picloram compound, the composition can effectively prevent and kill off the class weeds in wheat paddock, tool
Have expand degrass spectrum, synergistic effect is obvious, reduce amount of application, to crop safety the features such as.
A kind of Herbicidal combinations and its application of humulone containing polybenzobisoxazole and picloram, which is characterized in that the Herbicidal combination
The effective component of object is polybenzobisoxazole humulone and picloram.

2.3), processing mode
2.3.1), time and number are handled
It tests and shares medicine 1 time.To 1 heart stage of 2 leaf of weeds, thinning keeps 15 plants of weeds in every basin, and every processing retains 45 plants,
It then proceedes to cultivate to shepherd's purse, ox chickweed 3-5 leaf phase, 1 heart stage of 3 leaf of Alopecurus and be handled.
3) test method
Using pot-culture method.Weeds culture is shown in 2.1, reference《Farm-chemical indoor determination test rule herbicide》It carries out.
4), data survey and statistical analysis
4.1), investigation method
Using absolute number investigation method, the survival whole strain seedling of weeds is cut off along soil surface with blade, is weighed with assay balance
Weeds fresh weight.It is based on zero by fresh weight for dead weeds.
4.2), control time and number
It investigates within 20 days after processing, investigates 1 time altogether.
4.3), data statistic analysis
With Gowing method calculate it is each processing hybrid combining theoretical fresh weight inhibition rate (E0=X+Y-X*Y/100), then with
Actual measurement inhibiting rate (E) compares, and the mixed synergy type to weeds of both evaluations is made when E-E0 value is greater than 10% for synergy
With, be antagonism less than -10%, be addition between -10%~10%.And it is special according to practical preventive effect and herbicide
The factors such as the balance of point, formula determine optimum proportioning.
The fresh weight inhibition rate that X is active components A dosage in formula when being P；The fresh weight that Y is active constituent B dosage when being Q inhibits
Rate.
Statistical result see the table below.
1 active components A of the table practical preventive effect and synergy effect (Gowing to weeds mixed with picloram
Method)
Test result can be seen that composition of the invention and all have very well to broadleaf weeds shepherd's purse, ox chickweed from table
Preventive effect, have significant synergies between active constituent.
2) drug resistance effect test
Shepherd's purse (Capsella bursa-pastoris), Descurainia sophia (Descurainia sophi) seed deposit tribenuron-methyl
In resistance, Shandong Province Tai'an was collected in 2014.Test method：Weed seed is unified into vernalization, by pretreated for examination
Weed seed uniform broadcasting is in soil surface.It is administered the seedling in the ranks that advances, every basin final singling is to 30 plants, 4 basin test materials of each processing.To miscellaneous
Grass carries out cauline leaf spraying treatment, investigates weeds aerial part fresh weight, and calculating fresh weight preventive effect, (strain preventive effect is duplicate flat 4 times in table
Mean value), the statistical test situation after test 45 days, as a result such as following table：
Weed-control effect (%)=(clear water check plot weeds fresh weight-chemicals treatment district weeds fresh weight)/clear water check plot weeds
Fresh weight.
Table 2：Inhibit shepherd's purse, the Descurainia sophia effect test situation of resistance to ALS
Application Processing Example 1,2,3,4 can effectively prevent and kill off shepherd's purse, the Descurainia sophia that target resistance is generated to tribenuron-methyl, with
Cross resistance is not present in tribenuron-methyl.
