preparation Embodiment

[0025] In this example, if a 100-gram ternary herbicidal composition of sapylphos-atrazine-fluroxypyr is prepared, if the active ingredients are as follows: sapylphos:atrazine:fluroxypyr=5:30 : The proportioning ratio of 2 is prepared, and the weight of various active ingredients and auxiliary agents is required as follows:

[0026] Saponin 5g

[0027] Atrazine 30g

[0028] Fluroxypyr technical 2 grams

[0029] Alkylphenol polyoxyethylene ether formaldehyde condensate 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 water-suspension concentrate prepared by adding adjuvants and water to the original drug of saponin, atrazine and fluroxypyr through sand milling. The production method of this embodiment is as follows:

Abstract

The invention discloses a herbicide composition and a preparation method and application thereof. The ternary herbicide composition takes anilofos, atrazine and fluroxypyr with weight ratio of 1-20:5-50:1-20 as the active ingredients. The preparation method of the composition is characterized by firstly measuring the raw drugs and auxiliary agents, putting the measured raw anilofos, atrazine and application into a ball mill and then putting the auxiliary agents and water into the ball mill to be ball-milled for 2-3h, transferring the ball-milled products to a sand mill to be sand-milled for 3-4h, throwing the sand-milled products into a finished product preparation tank, carrying out sampling and analyzing and carrying out preparing. The composition is suitable for weed control in the fields, especially for weed control in the corn fields. The herbicide composition can show weed control effect in a short time and has good weed control effect, thus reducing the dosage of the herbicide.

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. 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 use...
