Description

A kind of wheat paddock herbicide
Technical field
The invention belongs to technical field of pesticide, relate to a kind of herbicide, be specifically related to a kind of wheat paddock herbicide.
Background technology
Semen Tritici aestivi is the most important cereal crops of northern China, concerning national economy and the grain security of country, mainly with the winter Semen Tritici aestivi is main, accounts for 90%, and the weeds of wheat paddock have impact on the growth of Semen Tritici aestivi.According to whole nation weeds reconnaissance information, China is little Wheat weeds kind has kind more than 200, crop smothering area to account for more than the 30% of wheat planting area, and loss accounts for Semen Tritici aestivi total output 15%, reach 10,000,000,000 kilograms.Semen Tritici aestivi main weeds has about 30 kinds, as amur foxtail, Alopecurus, Herba bromi japonici, annual bluegrass, hard grass, Caput grass, Miscanthus, Herba Galii Teneri, cattle Herba stellariae mediae, Herba veronicae, crack rice neat, pale persicaria, Stellaria alsine Grim., Herba Viviae Sativae, sarson, descurainia sophia (l.) webb ex prantl, Herba Viviae Sativae, corn gromwell, Herba Capsellae, Herba Euphorbiae Helioscopiae, Herba seu Flos Convolvuli arvensis, field thistle, rice crock, Herba chenopodii, little Herba chenopodii, Herba Polygoni Avicularis and Herba Lamii Amplexicaulis, wherein, wild swallow The harm such as wheat, amur foxtail, Herba Galii Teneri, descurainia sophia (l.) webb ex prantl is the most serious.
Along with long-term, the large scale application of herbicide, there is Weed Resistance, population succession in farmland weed chemical control It is on the rise with drug injury problem, has a strong impact on high yield and good harvest and the safety of succession crop of Semen Tritici aestivi.The most conventional Semen Tritici aestivi Field stalk leaf weedicide agent is only the best to broadleaved herb prevention effect, heterodyne anti-to grassy weed, and part is to effective right of gramineous grass Broadleaved herb effect is the most not all right, causes resistance weed very big simultaneously because some herbicide uses year after year, the weeds in wheatland It is increasingly difficult to kill.

The beneficial effects of the present invention is:
Herbicide of the present invention uses flucarbazone, mesosulfuron, Mediben and clodinafop-propargyl to compound, and four kinds of active component exist Fabulous synergistic function is shown in certain ratio range；Compared with weeding single dose, product of the present invention greatly improves Activity of weeding and herbicidal effect, reduce using dosage, effectively reduces the herbicide poisoning to Semen Tritici aestivi, and safety is high, right Succession crop does not affect, and the impact on ecological environment is the least, i.e. protects the interests of peasant, can significantly reduce again the labor of peasant Make intensity and work frequency, be particularly suitable for large-scale promotion.
Herbicide of the present invention expands herbicidal spectrum, cooperative compensating between four kinds of active component, exhausted to grow in wheat paddock Most of weeds all have good prevention effect, can kill except broadleaved herb and grassy weed simultaneously, solve existing herbicide The problem that weeding kind is single, and agent duration is long, can realize long-acting weeding, reduces the sprinkling number of times of herbicide, enters one Step reduces the poisoning to Semen Tritici aestivi.
The present invention further defines the dosage form of herbicide.One good herbicide products, it is necessary to have suitable dosage form Coordinate, just adapt to different edaphic condition and the demand of different weeds kind, reach convenience, safety and high efficiency. Herbicide of the present invention is emulsifiable concentrate, wettable powder, water dispersant, suspending agent or soluble concentrate, and these formulation of herbicides all have Having good stability, it is simple to store and transport, security performance is high, and weeding ratio is high.In use, can be according to used little The soil regime of wheatland and the difference of climatic environment, select the herbicide of dosage forms to carry out weeding, it is thus achieved that the most collaborative Synergistic effect, effectively kills remove grassy weed and broad-leaved section weeds.
The present invention, on the basis of formulation of herbicide, further defines kind and the usage ratio of each adjuvant；Adjuvant Select and appropriate addition makes the processing characteristics of herbicide and product serviceability significantly improve.The kind of adjuvant selects, no Only need consider dosage form product characterisitic parameter (such as, the pH value of suspending agent product, suspensibility, ionization rate, wet screening experiment, hold Foaming characteristic etc. for a long time), it is also contemplated that herbicide products absorption efficiency in soil and herbicidal effect.The consumption of adjuvant is excessive, removes Activity component concentration in grass agent is the lowest, is just unable to reach intended herbicidal effect；The consumption of adjuvant is the least, cannot ensure again to remove The stability of grass agent product, is unfavorable for actual application.Therefore, the herbicidal effect of herbicide is had non-with consumption by the kind of adjuvant The biggest impact, supplementary product kind that the present invention is limited and consumption, it is possible to reach maximized cooperative synergism effect, toxic action Under, stability is high.

The herbicide products of Example 1 ~ 5 preparation sprays in Shijiazhuang City of Hebei Province, and wheat breed is hundred agricultures 3217, apply as comparison with each active component list respectively, investigate killing except effect of several main weeds；Concrete data are shown in Table 1.
Table 1 weeds of wheat prevents and kill off data
By data in table 1 it can be seen that flucarbazone single dose is preferable, to wealthy to grassy weed wild oat, amur foxtail preventive effect Leaf weeds Herba Galii Teneri, descurainia sophia (l.) webb ex prantl preventive effect slightly worse；Grassy weed wild oat, amur foxtail are also had relatively by mesosulfuron single dose Good preventive effect, poor to the preventive effect relatively flucarbazone of broad leaved weed Herba Galii Teneri, descurainia sophia (l.) webb ex prantl；Mediben single dose to broad leaved weed Herba Galii Teneri, Descurainia sophia (l.) webb ex prantl has a favorable effect, but the most invalid to grassy weed wild oat, amur foxtail；Clodinafop-propargyl single dose is to grassy weed Wild oat, amur foxtail have a favorable effect, but the most invalid to broad leaved weed Herba Galii Teneri, descurainia sophia (l.) webb ex prantl.
And four kinds of active component use after compounding, all having good preventive effect to grassy weed and broad leaved weed, standing grain is originally Section weeds wild oat, the preventive effect of amur foxtail reach more than 90%, and broad leaved weed Herba Galii Teneri, the preventive effect of descurainia sophia (l.) webb ex prantl reach more than 85%, Expand herbicidal spectrum；And add the herbicidal effect to various weeds simultaneously, the product of the present invention compared with single dose, after compounding Synergistic effect is more than 20%, and effect is the most notable.
Being sprayed respectively in the wheat paddock of different cultivars by above-mentioned herbicide products, every kind of herbicide medicament is in different cultivars The amount of spraying in wheat paddock is identical, investigates its poisoning；Concrete data are shown in Table 2.
Table 2 herbicide damage data
By data in table 2 it can be seen that product of the present invention is the lowest, when using to the poisoning of common several wheat breeds Semen Tritici aestivi will not be produced harm, ensure the safety of crops.
Above-described embodiment is used for illustrating the present invention rather than limiting the invention, in the claims in the present invention Protection domain in, any modifications and changes that the present invention is made, both fall within protection scope of the present invention.
