Embodiment 1

[0019] Example 1: 24% trifluxysulfuron-amfenflurzone water-dispersible granules (1:15), including the following components with the following weight (based on 100 kg, the same below)

[0020] Trifloxysulfuron-methyl 1.5 kg, Mefentrazone 22.5 kg, Naphthalenesulfonate Sodium Formaldehyde Condensate 7 kg, Sodium Lauryl Sulfate 4 kg, Silicone Defoamer 0.5 kg, JFC 10 kg, White Carbon Black 4 kg , diatomaceous earth to make up to 100 kg.

[0021] Production method: Weigh each component of the above weight, mix them evenly, crush them with a high-speed airflow mill, mix them again, add water, knead and granulate them, dry and sieve to obtain 24% triflupyrsulfuron-amfentrazone water dispersion Granular product.

[0022] How to use: It is suitable for the treatment of stems and leaves in sugarcane fields. The dosage is 100-150 grams per mu, mixed with 30 kilograms of water, and sprayed evenly in calm and sunny conditions.

Embodiment 2

[0023] Example 2: 42% trifluxysulfuron-amfentrazone water-dispersible granules (1:20)

[0024] Trifluxysulfuron-methyl 2 kg, Mefentrazone 40 kg, Sodium Lignosulfonate 8 kg, Octylphenol Polyoxyethylene Ether 4 kg, Silicone defoamer 0.4 kg, JXS-201S (Nanjing Jixin Chemical) 8 kg, 3 kg of white carbon black, and diatomaceous earth make up to 100 kg.

[0025] Preparation method: with embodiment 1.

[0026] How to use: It is suitable for the treatment of stems and leaves in sugarcane fields. The dosage is 75-110 grams per mu, mixed with 30 kilograms of water, and sprayed evenly in calm and sunny conditions.

Embodiment 3

[0027] Example 3: 58% trifluxysulfuron-amfenflurzone water-dispersible granules (1:28)

[0028] Trifluxysulfuron-methyl 2 kg, Mefentrazone 56 kg, Sodium Lignosulfonate 8 kg, Sodium Lauryl Sulfate 5 kg, Silicone defoamer 0.5 kg, JXS-201S (Nanjing Jixin Chemical) 6 kg, diatomaceous earth to make up to 100 kg.

[0029] Preparation method: with embodiment 1.

[0030] How to use: It is suitable for the treatment of stems and leaves in sugarcane fields. The dosage is 75-110 grams per mu, mixed with 30 kilograms of water, and sprayed evenly in calm and sunny conditions.

Abstract

The invention relates to the technical field of pesticides, and particularly discloses weeding composition containing trifloxysulfuron and amicarbazone. The weeding composition comprises effective ingredients of trifloxysulfuron and amicarbazone, wherein the weight ratio of trifloxysulfuron and amicarbazone is 1:(15-50), the preferable weight ratio is 1:(20-30), the finally preferable weight ratio is 1:28, and the weight percentage of the effective ingredients accounts for 24%-81% of the total amount of a compound weedicide. The weeding composition has the benefits as follows: annual-growth grassy weeds, broad leaf weeds and cyperaceae weeds in a sugarcane field can be simultaneously prevented and killed off, particularly, the weeding composition has an effect on killing underground roots of cyperus rotundus of a malignant weed in the sugarcane field, and germination of tubers can be remarkably reduced. The weeding composition has a complementary weed-controlling spectrum and is remarkable in synergistic effect; the effective ingredientuse amount and the drug use times for per unit area are reduced, the drug resistance of weeds is delayed, the weeding composition has no phytotoxicity on sugarcrane, and the safety of an afterreap crop is high.

Description

【Technical field】 [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition containing trifluxysulfuron-methyl and amfentrazone. 【Background technique】 [0002] Sugarcane occupies an important position in my country's agricultural economy, and its output and output value are second only to grain, oilseeds and cotton, ranking fourth. Weeds in sugarcane fields are one of the important factors affecting the high quality and high yield of sugarcane. Field weeds not only compete with sugarcane for water, fertilizer, light and space, affecting the normal growth of sugarcane, but also become intermediate hosts and hosts of sugarcane diseases, insects, and rodents. The vector of transmission induces and aggravates the harm of sugarcane diseases, insects and rodents, thereby reducing the yield and quality of sugarcane. There are many kinds of weeds in sugarcane fields. At present, chemical control of weeds in sugarcane production is...
