Bandren is a diphenyl ether organic substance with broad spectrum activity against harmful plants in monocotyledonous and dicotyledonous

The herbicidal active compound Bandren belongs to diphenyl ether organics, and mixtures of such compounds with other herbicides are known in the literature, and in particular, mixtures of heteroaryloxyacetamides and individual active compounds (eg, herbicide Bandren) are described; however , There is no experimental data on synergies. The herbicidal active compound Bandren is characterized by having a broad-spectrum activity against harmful plants of monocotyledonous and dicotyledonous plants, and is mainly used, for example, by pre-emergence methods for sowing or planting agricultural crops or horticultural crops and on non-crop land (such as cereals (such as wheat , Barley, rye, oats, triticale, rice, corn, millet), sugar beet, sugar cane, rape, cotton, sunflower, soybean, potato, tomato, beans, flax, pasture, fruit plantation, planted crops, green space and Lawn, and squares and tracks in residential or industrial areas.

application

As a separate active compound, Bandren is commercially available. Bandren is a diphenyl ether herbicide and is an inhibitor of protoporphyrin oxidase. Pre-emergence application can control broad-leaved weeds such as sunflower, potato and winter wheat fields and grass weeds. Field trials on carrots, peas, and fava beans showed that when applied, the control effect on windweed was 97%, and the control effect on rat tail maidenhair was more than 90%, which was equivalent to its control agent green mellon. The control effects on chickweed, wild sesame, pigs, wild forget-me-not, ivy, grandmother, Persian bitterweed and heliotrope are all higher than the control agents; the control effects on wheat vines and matricaria are lower than the control agents . It is not harmful to crops. After the soil is ploughed, it can be planted within 4 weeks after applying the pesticide.

Under the trade name and in addition to the use of individual compounds, mixtures of Bandren and other herbicides are also known in the literature and are commercially available: mixtures with amitrole (eg IllicoTL), and isoxazole Mixtures of isoxaflutole (e.g. Merlin), mixtures with alachlor (e.g.), mixtures with flurtamone (e.g.), mixtures with oxadiargyl (e.g. ) And mixtures with oxadiazon (for example). The application examples are as follows:

1) Preparation of a herbicidal composition containing dicamba and Bandren and its application. The herbicidal composition uses dicamba and Bandren as the main active ingredients, and the mass ratio of dicamba to Bandren is 1-60:1-60. The herbicidal composition of the present invention can be used for weeding post-emergence in winter wheat fields, especially for controlling grasses and broad-leaved weeds in winter wheat fields.

2) Preparation of a herbicidal composition containing sulfamethoxazole and Bandren, wherein the effective ingredients are sulfamethoxazole and Bandren, and the weight ratio of the sulfamethoxazole and Bandren is 1:10 to 10:1. The invention is used for preventing and controlling annual grass weeds such as wheat field weed brome and arthropod. The medicinal efficacy test shows that the complementarity between the active ingredients of the composition is used to improve the control effect on weeds and make up for weeding The shortcomings of the agent when used alone are conducive to delaying weed resistance and safe to wheat crops, and have good application prospects.

3) Preparation of the formulation in the form of an aqueous dispersion, comprising the following components: Bandren and flufenazone; a mixture of anionic surfactants and nonionic surfactants, the anionic surfactant is selected from naphthalene sulfonate or A condensation product of naphthalene sulfonate and formaldehyde, the nonionic surfactant is selected from diblock and triblock copolymers of alkylene oxide; a specific mixture of organic and inorganic thickeners; The aqueous dispersion is added with other agrochemical active substances and other commonly used auxiliaries and additives. The aqueous dispersion has high storage stability and is suitable for the field of plant protection.
