Description
Technical field
The present invention relates to a kind of herbicide, particularly a kind of biological source herbicide composition, belong to field of agrochemicals.
Background technology
Weeds distribution turns into one of main bugbear faced in Agro-ecological System and garden, turf management.Chemical weed control
Agent accounts for the principal status of public economy because its effect is rapid, significant effect and the features such as saving of work and time in Weeds distribution.However, due to using
Reason, the chemical herbicides such as the drift of improper and droplet, leaching, decoction volatilization not only have a strong impact on crop growth, simultaneously
The problems such as bringing residual hazard poisoning, polluted source, Practice for Pesticide Residue in Agricultural Products.Biological source herbicide has compared with chemical herbicide
The advantages that easy natural degradation, Environmental compatibility are high, comparatively safe to target organismses, particularly takes from plant and fungi, bacterium
Deng the herbicidal active compoundses of microorganism, not only source is compared with horn of plenty, the target selection of the mode of action and height with more uniqueness
Property.Therefore, be compatible with the environment, safety low to non-target organism toxicity, harmful organism is not likely to produce the resistance to the action of a drug to it, toxicity into
Divide comparatively fast to degrade in natural environment, in the absence of the biogenic substances agricultural chemicals of residue problem, in pollution-less agriculture production and green
Had broad application prospects in food production.N-nonanoic acid is a kind of aliphatic acid being widely present in animal and plant body, is being planted
More in thing to be present in the form of ester in essential oil, only a few exists in the form of free state, micro- poison, degradable in soil, is tactile
Killing property, wide spectrum, nonselective herbicide, annual and perennial broadleaf weed can be prevented and kill off, its herbicide effect causes people's
Concern, there is document report its activity of weeding, herbicide controlling spectrum, mechanism of action and an application effect successively, LG-DOW (DOW) company with
Trade name SCYTHE registrations are introduced to the market prevents and kill off (in August, 2006) for garden and turf weed, at the same time american agriculture
N-nonanoic acid is also used for Weeds distribution in organic agriculture production and is assessed also to obtain and pass through by portion.But n-nonanoic acid is used in management of weeds
Dose is larger, and to the too late effect to broad leaved weed of activity of grassy weed, thus dosage is often increased, increase warp
Ji cost.Money shake official rank carried out botanical herbicides n-nonanoic acid activity of weeding and its application technology research (Shanghai Agricultural journal,
2010,26 (2)：1-4), field control effectiveness test result shows that per hectare dosage is 40000 grams of effective ingredient, after medicine 7 days to standing grain
Undergraduate course weeds amur foxtail and the strain number preventive effect for deceiving grass are respectively 95.77% and 100%, to the strain number preventive effect of broad leaved weed ox chickweed
For 100%；Liu Jie etc. carried out biological source herbicide n-nonanoic acid to the preventive and therapeutic effects of bare place weeds (Chinese agronomy circular 2012,
28(27):246-249), result of the test shows that per hectare dosage is that effective ingredient is 40000 grams and could effectively control weeds.
The content of the invention
It is an object of the invention to overcome deficiency and defect of the prior art, there is provided a kind of using n-nonanoic acid as main component
