Abstract
The invention relates to the field of herbicides, and discloses a liquid herbicide composition and application thereof. The composition contains the following components which are stored in a mixing way or independently: based on the total weight of the composition, component a: 0.01-30 wt% of clethodim, component b: 0.5-20 wt% of at least one of alkyl succinate sulfonate and its derivatives; and (c) component: 6-45% by weight of an emulsifier; and (b) a component d: 15-88% by weight of a solvent. The composition provided by the invention has good stability and weeding effect.
Description
Technical Field
The present invention relates to the field of herbicides, in particular to a liquid herbicide composition and its use in inhibiting or controlling undesirable monocotyledonous weeds and/or undesirable crop growth.
Background
The weeds in the paddy field mainly comprise grassy weeds such as barnyard grass, moleplant seeds and crabgrass, broadleaf weeds such as dayflower, alternanthera philoxeroides and sedge weeds such as sedge grass and cyperus rotundus, and the weeds are mixed, have high generation density and are difficult to control.
At present, methods for controlling weeds in paddy fields are divided into sealing treatment and stem and leaf spray treatment, and stem and leaf spray control is taken as a main means. However, the weeds have certain resistance to conventional medicaments such as quinclorac, penoxsulam, metamifop and the like, the control difficulty is increased, and the control cost is increased.
The phenthodim (structural formula shown below) is also a cyclohexenone herbicide, and has an ACCase inhibitor action mode. Is mainly used for preventing and controlling barnyard grass, moleplant seed, large crabgrass and golden green bristlegrass in the paddy field.
The structural formula of clethodim is:
cyclohexenone herbicides generally contain functional groups such as hydroxyl, double bond, oxime, etc., and are easily decomposed by oxygen, moisture, ultraviolet rays, temperature, etc. in daily environments. Due to the characteristic that the original drug is easy to decompose, the stability of the preparation is poor, and taking clethodim as an example, the thermal stability of the clethodim is specified in GB 22615-2008: the preparation is carried out according to the 'liquid preparation' in GB/T19136, and the hot storage condition is (35 +/-2) DEG C for 12 weeks. After heat storage, the mass fraction of clethodim is not less than 90% of the mass fraction of clethodim measured before storage. The heat storage condition of the conventional product is (54 +/-2) DEG C for 2 weeks, and the decomposition rate is required to be not higher than 5%; it follows that the decomposition of the cyclohexenone type products is a recognized problem.
Similar to other cyclohexenone herbicides, the problem that the benzoxydim is easy to degrade after being stored for a long time also exists. Therefore, one of the objects of the present invention is to select specific adjuvants and solvent systems to solve the problem of degradation of phenicol during long-term storage.
Disclosure of Invention
One of the purposes of the invention is to solve the problem that the phenthodim preparation provided by the prior art is easy to degrade after being stored for a long time.
The invention also aims to reduce the dosage of active components in the clethodim preparation on the premise of ensuring the weeding effect of the clethodim preparation on harmful weeds.
In order to achieve the above object, a first aspect of the present invention provides a liquid herbicidal composition comprising herbicidally effective amounts of two or more of the following components stored in admixture or separately: based on the total weight of the composition,
a component a: 0.01-30% by weight of clethodim,
and (b) component b: 0.5-20 wt% of at least one of alkyl succinate sulfonate and its derivatives;
and (c) component: 6-45% by weight of an emulsifier;
and (b) a component d: 15-88% by weight of a solvent.
A second aspect of the invention provides the use of a liquid herbicide as described above for inhibiting or controlling undesirable monocotyledonous weeds and/or undesirable crop growth.
The composition provided by the invention has good stability in long-term storage and has good weeding effect on harmful weeds.
Detailed Description
The endpoints of the ranges and any values disclosed herein are not limited to the precise range or value, and such ranges or values should be understood to encompass values close to those ranges or values. For ranges of values, between the endpoints of each of the ranges and the individual points, and between the individual points may be combined with each other to give one or more new ranges of values, and these ranges of values should be considered as specifically disclosed herein.
As described above, the first aspect of the present invention provides a liquid herbicidal composition comprising a herbicidally effective amount of two or more of the following components stored in admixture or separately: based on the total weight of the composition,
a component a: 0.01-30% by weight of clethodim,
and (b) component b: 0.5-20 wt% of at least one of alkyl succinate sulfonate and its derivatives;
and (c) component: 6-45% by weight of an emulsifier;
and (b) a component d: 15-88% by weight of a solvent.
The inventor finds that the invention adopts a specific amount of alkyl succinate sulfonate and derivatives thereof to replace calcium dodecyl benzene sulfonate, which not only can effectively inhibit the decomposition of the benzoxydim preparation, but also can obviously increase the drug effect of the benzoxydim preparation.
