preparation Embodiment

[0025] In the present example, if 100 grams of a ternary herbicidal composition of promezam, thifensulfuron-methyl, and acetochlor is prepared, if the active ingredients are formulated according to the formula of promezam: thifensulfuron-methyl: acetochlor=17:0.8:60.2 For preparation, the weights of various active ingredients and additives are required as follows:

[0026] Acetochlor technical 60.2g

[0027] Promethazine 17g

[0028] Thifensulfuron-methyl technical 0.8g

[0029] Alkylphenol ethoxylates 3 g

[0030] Sodium lignosulfonate 2 g

[0031] Pull open powder 1g

[0032] NNO 3 grams

[0033] Xanthan gum 0.5g

[0034] Organic silicone 0.5g

[0035] Ethylene glycol 1 g

[0036] Water to make up to 100g

[0037] see figure 1 The composition of the herbicide of the present invention is a suspoemulsion formed by adding adjuvants and water to the original drug of acetochlor, prometon and thifensulfuron-methyl through sand milling. The production method of this embo...

Abstract

The invention discloses a weedicide composition and a preparation method and use thereof. The weedicide composition is a ternary weedicide composition consisting of prometryn, thifensulfuron and acetochlor serving as active ingredients, wherein the weight ratio of the prometryn to the thifensulfuron to the acetochlor is 1-40:0.5-10:1-70. The method for preparing the composition comprises the following steps of: firstly, metering original medicaments and an aid; secondly, putting the metered prometryn original medicament, the thifensulfuron original medicament and the acetochlor original medicament into a ball mill and then putting the aid and water into the ball mill; thirdly, performing ball milling for 2 to 3 hours; fourth, transferring the mixture into a sand mill and performing sand milling for 3 to 4 hours; and lastly, putting the mixture into a finished product preparation tank, sampling for analysis and preparing. The composition of the invention is suitable for preventing and removing in-field weeds. The weedicide composition of the invention can show weed removing effect in a very short period of time and has good weed removing effect, so that the using amount of a weedicide is decreased.

Description

technical field [0001] The invention relates to a herbicidal composition for controlling farmland weeds, a preparation method and application thereof. Background technique [0002] Chemical weeding is the development trend of modern agriculture. Chemical herbicides have been widely used in agricultural production and have produced great economic benefits. However, the herbicidal spectrum of various herbicides has its limitations, and the period of use is also limited. Moreover, the use of a single agent can easily cause phytotoxicity and cause crops to develop resistance. Therefore, the reasonable mixed use of pesticides is the current development trend of pesticides, and has its strong advantages. Reasonable mixed use can expand the scope of weed killing, and at the same time, it can also extend the use period of pesticides. It is not only used for soil sealing before seedlings, but also stems and leaves after seedlings. Control field weeds. Reasonable mixed use of chemi...
