Description
Technical field
The present invention relates to pesticide products, and in particular, to a kind of winter wheat field herbicide and preparation method thereof.
Background technique
Herbicide, which refers to, can make weeds that withered medicament, also known as herbicide thoroughly or selectively occur, eliminating or
Inhibit a substance of plant growth.Sodium chlorate therein, borax, arsenate, trichloroacetic acid for any kind of plant all
Play the role of it is withered, effect influenced by herbicide, plant and three factor of environmental condition.It is divided into go out natural disposition and selection by effect
Property herbicide, selective herbicide especially nitrophenol, chlorophenol, carbamic derivative majority are all effective.
Herbicide its, insecticide, fungicide use for the moment mistake higher using the requirement of technology compared with insecticide, fungicide
When, it may be influence control efficiency, and herbicide improper use, concerning the safety of plant growth.It generally investigates and provides according to national weeds
Material report, China's wheat weeds type have more than 200 kinds, and crop smothering area accounts for 30% or more of wheat planting area, and loss accounts for about small
The 15% of wheat total output, up to 10,000,000,000 kilograms, wherein the harm such as ox chickweed, clearvers, Descurainia sophia, common vetch are serious.But with removing
Long-term, the large scale application of careless agent, there are Weed Resistance, population succession and drug injury problems for farmland weed chemical control increasingly
Seriously, the high yield and the safety of good harvest and succession crop of wheat are seriously affected.Currently, commonly using medicament in wheatland, there are some disadvantages
End.Such as sulfonylurea herbicide tribenuron-methyl, bensulfuron-methyl dosage it is excessively high and too late using can be caused to succession crop peanut, soybean
Phytotoxicity.Phenoxy carboxylic acid herbicides 2,4- d butyl ester, mcpa sodium dosage are excessively high and application is improper easily causes chemical injury of crops
Phytotoxicity can be generated to neighbouring dicotyledonous crops by generating drift.In addition if single herbicide is used for a long time, to prevent and kill off sensitization miscellaneous
Careless quantity decline, insensitive or malignant weed quantity rise, and weed community is caused to change.In herbicide single use
Serious variation has occurred in winter wheat producing region, weed community in wheat field, and a variety of herbicides such as clearvers, wartwort, grandmother's sodium, shepherd's purse are equal
The malignant weed for being difficult to prevent and treat increases year by year, and has seriously affected the harvest of wheat crop yield.
Therefore it provides the winter wheat field herbicide that a kind of degradation is slow and herbicidal effect is excellent is very important.
