Description
Technical Field
The invention relates to the technical field of plant protection, and particularly relates to a herbicide composition containing glyphosate and application thereof.
Background
And (3) chloracetyl phosphinyl: the chemical name is O, O-dimethyl-1- (2, 4-dichlorophenoxyacetoxy) ethyl phosphonate, the molecular formula is C12H15Cl2O6P is a novel herbicide with independent intellectual property rights in China, is developed by university of Master in China, belongs to a substituted phenoxyl acetoxyl alkyl phosphonate compound, and is a strong inhibitor of a pyruvic acid dehydrogenase system. The chloracetyl phosphinothricin has the characteristics of novel structure, high activity, wide weed control spectrum, strong systemic property, low toxicity, low residue and environmental ecological safety, and is the only commercial herbicide taking pyruvate dehydrogenase as a target at present. The cloransulam-methyl serving as a selective herbicide has good application and development prospects in gramineous crop fields such as wheat, corn, rice and the like and gramineous lawns.
For example, wheat is one of the most important food crops in China, and the planting area is about 2500 million hectares every year in China, so that the control of weeds in wheat fields is very important. The chemical pesticide for preventing and killing weeds in wheat fields mainly uses a few herbicide varieties represented by tribenuron-methyl for many years, and due to long-term repeated or unscientific use of the herbicide varieties, the resistance of weeds in wheat fields is serious (for example, the resistance of descurainia sophia to tribenuron-methyl is already serious), so that the dosage is increased, the prevention and treatment cost is increased, the residue is increased, and the risk of environmental ecology is increased. The chloracyl phosphinothricin has a brand-new action target, so that the chloracyl phosphinothricin is very sensitive to some resistant weeds and shows excellent control effect.
The chloracetyl phosphinothricin is used as a selective herbicide to effectively prevent and kill off broadleaf weeds and cyperaceous weeds in gramineous crop fields such as gramineous lawns, wheat, corns and rice as well as orchards, tea gardens and uncultivated areas, but as a new herbicide variety, the weed control spectrum and the agricultural application range of the novel herbicide are worthy of further expansion. The development of the novel herbicide composition of the chloracyl phosphinothricin is an effective way for expanding the weed control spectrum of the chloracyl phosphinothricin and expanding the application range of the chloracyl phosphinothricin, and is one of important improvement targets for popularization and application of the chloracyl phosphinothricin at present. Therefore, the effect of the chloracetyl phosphinothricin in preventing and controlling weeds in gramineous crop fields such as gramineous lawns, corns and paddy rice, orchards, tea gardens and uncultivated areas can be improved.

Example 8
The field test of the herbicide composition preparation is carried out in winter wheat, spring wheat, corn fields, paddy fields, tea gardens or orchards, and is mainly directed to various annual and perennial broadleaf weeds, grassy weeds and sedge weeds, such as speedwell, cleavers, capsella bursa-pastoris, descurainia sophia herb, chickweed, quinoa, vetch, abutilon, amaranthus retroflexus, cirsium japonicum, cyperus rotundus, crowndaisy chrysanthemum, eclipta prostrata, eclipta alba, barnyard grass, digitaria sanguinea, alopecurus setosa, setaria viridis, cyperus rotundus, hordei, carex sibirica, cardamon, garland stubbles, cress, stephania japonica, stringy swingle, endive, field bindweed, spiny weed, and the like. For example, when the herbicide composition is formulated for weeding in wheat, the application time can be set atThe herbicide is applied to the wheat in the seedling stage or 3-5 leaf stage after the three-leaf stage to the jointing stage. Each cell area is 20m2Random block arrangement, investigation of weed species and number before application. Spray treatment with stem leaves was used, with 4 replicates of each treatment. The control effect of the herbicide composition on weeds was investigated 90 days after application (or 30 days, see table 8), and the overall control effect was calculated according to the number of survival of weeds. The field pesticide effect calculation calculates the plant control effect and fresh weight control effect according to a formula in the pesticide field pesticide effect test criterion (I).
The weed decline rate (%) is (number of weed plants before application-number of weed plants after application)/number of weed plants before application × 100;
the plant control effect (%) (the treated zone weed decline rate-the control zone weed decline rate)/(100-the control zone weed decline rate) × 100;
fresh weight control effect (%). The fresh weight of weeds in the treatment area/the fresh weight of weeds in the control area is multiplied by 100.
(in tables 1 to 8: kg a.i/ha/kg of active ingredient/ha)
The results of the field efficacy of the herbicide compositions of various formulations prepared according to the examples applied to winter wheat, spring wheat, corn fields, paddy fields, tea gardens or orchards are shown in the following tables:
table 1: results of pesticide effect test of herbicide composition (emulsifiable solution)
Herbicidal composition emulsifiable concentrates were prepared as in example 1.
Table 2: results of efficacy test of herbicide composition (wettable powder)
Wettable powders of herbicidal compositions were prepared as in example 2.
