Embodiment 1

[0030] Example 1: Activity of the composition

[0031] Greenhouse potting method was used to study the herbicidal activity of Fenoxaprop-P-P and dicamba in different proportions on the main weeds in wheat fields such as clubhead grass, scallops, curly ears, and cattail. The results are shown in Table 1 and Table 1. 2. Table 1 is the control effect (%) of the mixture of fenoxaprop-p-ethyl and dicamba on weeds; Table 2 is the type of joint action of the mixture of fenoxaprop-p-ethyl and dicamba on weeds.

[0032] The control effect (%) of table 1 fenoxaprop-ethyl and dicamba mixed to weeds

[0033]

[0034] Table 2 Types of combined effects of fenoxaprop-ethyl and dicamba on weeds

[0035]

[0036] The results showed that the activity of fenoxaprop-ethyl against grassy weeds Clifax and Trichosanthes was 45.0%-94.98% and 45.0%-91.3%, respectively, and it was ineffective against broad-leaved weeds P. The activities of dicamba against Clovergrass and Trichosanthes were 24....

Embodiment 2

[0037] Embodiment 2: recipe example

[0038] Formula 1: Fenoxaprop-P-P-P 5%, Dicamba 10%, Metoxazole 5%, Sodium Lignosulfonate 2%, Alkylphenol Formaldehyde Resin Polyoxyethylene Ether 10%, White Carbon Black 2%, Yellow Raw gum 0.1%, propylene glycol 2%, silicone defoamer 0.2%, water to make up to 100%. After the material is coarsely crushed and homogenized, it is ground by a sand mill until the particle size reaches the standard requirement, and then filtered to obtain 15% fine oxaprop-ethyl dicamba suspension concentrate.

[0039] Formula 2: Fenoxaprop-P-P-P 10%, Dicamba 20%, Mecloxazone 5%, Methylcellulose 2%, Sodium Lignosulfonate 3%, White Carbon Black 2%, Kaolin supplemented to 100%. The material is ultrafinely pulverized to obtain a wettable powder of 30% oxaprop-ethyl dicamba.

[0040] Formula 3: Fenoxaprop-P-P-P 5%, Dicamba 20%, Mecloxazone 5%, 200# solvent oil 20%, Calcium Dodecyl Benzene Sulfonate 3%, Silicone defoamer 0.1%, materials Stir after mixing, dissolve i...

Abstract

A fenoxaprop-p-ethyl and dicamba composition contains two active ingredients: fenoxaprop-p-ethyl and dicamba. The composition preparation is prepared from fenoxaprop-p-ethyl, dicamba, a solid or liquid carrier and assistants and is used for controlling the weeds in the wheat fields. The composition has obvious additive effect, and compounding fenoxaprop-p-ethyl and dicamba can synthetically consider the joint effect types, herbicidal activities and economic cost of the two drugs.

Description

technical field [0001] The invention relates to a pesticide composition, which is a binary compound composition for controlling weeds in wheat fields, in particular to a composition of fenoxaprop-p-ethyl and dicamba. The invention belongs to the technical field of pesticide herbicides. Background technique [0002] Fenoxaprop-p-ethyl (chemical name: 2-[4-(6-chloro-1,3-benzoxazol-2-yloxy)phenoxy]ethyl propionate) belongs to phenoxycarboxylic acid herbicides Its mechanism of action is to inhibit the synthesis of fatty acids, and it can be used to control annual and perennial grass weeds in various dicotyledonous crops. [0003] Dicamba (chemical name: 3,6-dichloro-2-methoxybenzoic acid) is a systemic herbicide of the benzoic acid system. It is absorbed by the roots and leaves of weeds after the treatment of stems and leaves after emergence, and passes through the phloem and xylem up and down. Transduction, hindering the normal activity of plant hormones to produce medicinal ...
