Embodiment 1

[0041] Embodiment 1: Indoor toxicity assay:

[0042] In order to understand the combined effect of flumifenac and mesotrione on weeds, the following experiments were carried out:

[0043] Test method: Fill the test soil quantitatively to 4 / 5 of the pot, and use top watering to make the soil completely wet to saturated. Sow the pretreated weed seeds evenly on the soil surface, cover the soil with 0.5cm, keep the soil fully moist after sowing, move them into the greenhouse for routine cultivation, and apply pesticides until the weeds grow to the 2-3 leaf stage. Every 20 weed seeds was regarded as a treatment, and each treatment was repeated 4 times. Calculate the control effect, and then use the least square method to calculate the inhibitory medium concentration EC 50 (95% confidence interval), and then use the Sun Yunpei method to calculate the co-toxicity coefficient (CTC). Co-toxicity coefficient (CTC) ≥ 120 represents synergistic effect; co-toxicity coefficient (CTC) ≦ 8...

Embodiment 2

[0051] Example 2: 15% diflufenamide·\Mesotrione SC

[0052] Flupyramid 3%, Mesotrione 12%, AEO-34%, Sodium Polyacrylate 8%, Polyvinyl Alcohol 1%, Water 100%, after thorough mixing and grinding, 15% Flupyramid Amines \Mesotrione SC.

Embodiment 3

[0053] Example 3: 40% diflufenamide·\Mesotrione SC

[0054] Flupyramid 4%, Mesotrione 36%, T-603%, Calcium Lignosulfonate 7%, Xanthan Gum 1.5%, Water Supplement 100%, after thorough mixing and grinding, 40% flupirin Amylamide·\Mesotrione SC.

Abstract

The invention relates to the field of pesticide preparations and discloses a herbicide composition. The herbicide composition comprises picolinafen and mesotrione in a weight ratio of (1:0.2)-(1:10). The invention also provides herbicide composition preparations. The active ingredients of the herbicide composition preparations are formed by the herbicide composition. The herbicide composition and conventional auxiliary materials can be prepared into such dosage forms as suspending agents, wettable powder or water dispersible granules according to the known methods. The herbicide composition has the following beneficial effects that the herbicide composition is formed by compounding picolinafen and mesotrione, expands the weed-controlling spectrum, can simultaneously control most weeds in the corn fields, enhances the effect of controlling such weeds as barnyard grass, crab grass, field bindweed and cirsium setosum, simultaneously has the advantages of long use age, safety to later crops, long duration and environmental safety and can be widely applied to the field of agriculture.

Description

technical field [0001] The present invention relates to the field of pesticide preparations, in particular to a herbicidal composition, especially a herbicidal composition whose active ingredients are composed of flumetrachlor and mesotrione. Background technique [0002] Corn is one of the most widely distributed food crops in the world, and its planting area ranks third after corn and rice. There are two famous corn golden belts in the world, located in the United States and China. China is the world's second largest corn producer and also the world's second largest consumer. Corn is the most suitable variety of industrial raw materials among the three major food crops, and it is also the most processed food crop. The corn processing industry is characterized by large processing space, long industrial chain, and extremely rich products, including eight series of starch, starch sugar, modified starch, alcohol, enzyme preparation, condiment, medicine, and chemical industry...
