Example Embodiment

[0030] Example 1: Activity of the composition

[0031] Greenhouse potting method was used to study the herbicidal activity of different combinations of fenoxaprop-p-ethyl and dicamba on the main weeds in wheat fields, such as scorpion grass, pottery grass, curl ears, and pig worms. The results are shown in Table 1. 2. Table 1 shows the control effect (%) of mixed pair of fenoxaprop-ethyl and dicamba weeds; Table 2 shows the combined action type of mixed pair of fenoxaprop and dicamba weeds.

[0033]

[0034] Table 2 Combination types of weeds in the mixed pair of fenoxaprop-p-ethyl and dicamba

[0035]

[0036] The results showed that the activity of Fenoxaprop-p-ethyl on the grass weeds Corynegrass and Snakeweed was 45.0%~94.98% and 45.0%~91.3%, respectively, and it was not effective on the broad-leaved weeds Fructus vulgaris and Sorbus. The activities of dicamba against Cobra and calamus are 24.71%...

[0037] Example 2: Formulation example

[0038] Formulation 1: Fenoxaprop-ethyl 5%, Dicamba 10%, Meclofen 5%, Sodium lignosulfonate 2%, Alkylphenol formaldehyde resin polyoxyethylene ether 10%, White carbon black 2%, Yellow 0.1% of raw gum, 2% of propylene glycol, 0.2% of silicone defoamer, and water to make up to 100%. After the materials are coarsely crushed and homogenized, they are ground by a sand mill until the particle size meets the standard requirements, and then filtered to obtain 15% fenoxaprop-ethyl dicamba suspension.

[0039] Formula 2: Fenoxaprop-p-ethyl 10%, dicamba 20%, mexazole 5%, methyl cellulose 2%, sodium lignosulfonate 3%, silica 2%, kaolin supplement to 100%. After the material is superfinely pulverized, a 30% refined dicamba wettable powder of fenoxaprop-p-ethyl is obtained.

[0040] Formulation 3: Fenoxaprop 5%, dicamba 20%, mexazole 5%, 200# solvent oil 20%, calcium dodecylbenzene sulfonate 3%, organic silicon defoamer 0.1%, materials After mixing, stir t...

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 ...
