preparation Embodiment

[0027] In this example, if 100 grams of nicosulfuron-atrazine-octanoylbromoxynil ternary herbicidal composition is prepared, if the active ingredients are formulated as follows: nicosulfuron: atrazine: octanoylbromoxynil=3 : 22:13 ratio for preparation, the weight of various active ingredients, additives, and solvents is as follows:

[0028] Nicosulfuron technical 3 grams

[0029] Atrazine 22g

[0030] Bromoxynil Octanoyl 13g

[0031] Cetyl Sorbitan 3 g

[0032] Sodium lignosulfonate 2 g

[0033] Alkylphenol ethoxylates 3 g

[0034] NNO 3 grams

[0035] Xanthan gum 0.5g

[0036] Organic silicone 0.5g

[0037] Ethylene glycol 1 g

[0038] Sodium Benzoate 0.5g

[0039] Soybean oil to make up to 100g

[0040] see figure 1 , the composition of the herbicide of the present invention is an oil suspension prepared by adding adjuvants and solvents to the original drug of nicosulfuron, atrazine and bromoxynil octanoyl and processed by sanding. The production method of this ...

Abstract

The invention discloses a weedicide composition, a preparation method thereof and application thereof. The weedicide composition is a ternary weedicide composition consisting of nicosulfuron, atrazine and bromoxynil octanoate which serve as active ingredients, wherein the weight ratio of the nicosulfuron, the atrazine and the bromoxynil octanoate is 1:10:5-50:1-30. The preparation method of the composition comprises the following steps of: melting the metered bromoxynil octanoate, throwing the melted bromoxynil octanoate into a ball mill, adding unprocessed pesticides of the nicosulfuron and the atrazine, an auxiliary agent and a solvent into the ball mill, performing ball-milling for 2 to 3 hours, adding the mixture into a sand grinder to grind for 3 to 4 hours, pumping the mixture into a blending tank of a finished product, sampling to analyze and blending. The composition is applicable to prevention and removal of weeds in fields, particularly to the prevention and removal of weeds in a maize field. The weedicide composition of the invention can take the effect of removing seeds in very short time and has good seed removing effect, so that the using amount of weedicides can be reduced.

Description

technical field [0001] The invention relates to a herbicide composition for controlling weeds in farmland, in particular to a herbicide composition for controlling gramineous weeds and broadleaf weeds in corn fields, a preparation method and application thereof. Background technique [0002] Chemical herbicide is the development trend of modern agriculture. At present, chemical herbicides have been widely used in corn in northern my country, which has produced great economic benefits. Among them, the compound nicosulfuron is a new type of herbicide, which can be used to control monocotyledonous and dicotyledonous weeds in corn fields. It can kill both grass and broadleaf. It has a good effect on corn after seedlings, and is highly safe for corn. However, due to the low content (below 4.1%) of this medicament at present, the drug effect is not ideal, and the existing compound nicosulfuron cooperates with other medicaments, so it cannot be used for older weeds, and the effecti...
