Problems solved by technology

At present, there are many kinds of chemical herbicides for wheat, but most of them have various problems, such as narrow herbicidal spectrum of a single herbicide, easy to produce resistance, short duration of effect, narrow use period of binary herbicide composition, Issues such as insecurity of subsequent crops
In recent years, the reasonable selection of herbicides in wheat fields has become an important link to ensure the safety of wheat production. However, due to improper selection of herbicides or inadequate use of technology, the control effect is not ideal or the phenomenon of phytotoxicity occurs frequently.
For example, many of the stem and leaf herbicides used have better control effects on broad-leaved weeds, but poor control effects on gramineous weeds; poor effect

Embodiment 1

[0038] Embodiment 1: the control effect test of herbicidal composition of the present invention to weeds

[0039] The test is to use 95% florasulam technical (A), 97% metosulam technical (B) and 97% fluroxypyr technical (C) as active ingredients respectively, and add appropriate amount of auxiliary agent See Table 1 for the prepared suspension concentrates, test treatments and application rates.

Embodiment 2

[0046] Example 2: 35% florasulam·methoxysulam·fluroxyfen suspension concentrate

[0047] Flumesulam 1%, Methosulam 1%, Fluroxypyr 33%, Sodium Lauryl Sulfate 6%, Sodium Lignosulfonate 4%, water to 100%, fully mixed, After being pulverized, a 35% suspension concentrate of florasulam·methoxysulam·fluroxyfen was obtained.

[0048] The herbicides prepared in this example were compared with the herbicides made from florasulam, methoxsulam, or fluroxyfen with a single active ingredient and the herbicides made from two active ingredients in combination. The amount of active ingredients is calculated according to the standard, and under the premise that the amount of each active ingredient in the herbicide is less than the amount of each single agent or compound active ingredient, its control effect is higher than that of a single agent or a combination of two single agents, It can effectively control most of the weeds in the wheat field, and it has enhanced control effect on grassy w...

[0049] Example 3: 38% florasulam·methoxysulam·fluroxyfen suspension concentrate

[0050] Flumesulam 1%, Methosulam 2%, Fluroxypyr 35%, Sodium Lauryl Sulfonate 5%, Sodium Lignosulfonate 6%, Water to 100%, Mix well , After pulverization, a 38% suspension concentrate of florasulam·methoxysulam·fluroxyfen was obtained.

[0051] The herbicides prepared in this example were compared with the herbicides made from florasulam, methoxsulam, or fluroxyfen with a single active ingredient and the herbicides made from two active ingredients in combination.

Abstract

The invention relates to the field of pesticide preparations and discloses a herbicide composition. The herbicide composition comprises florasulam, pyroxsulam and fluroxypyr, and the weight ratio of the florasulam to the pyroxsulam to the fluroxypyr is 1: (1-3): (33-50). The invention further provides a herbicide taking the herbicide composition provided by the invention as an active ingredient. The herbicide composition, together with conventional auxiliaries and a carrier, can be prepared into the herbicide of the preparation formulations, such as water dispersible granules, suspension concentrate and the like according to the known method. The herbicide composition has the beneficial effects of expanding the weed control spectrum, improving the control effect against grass weeds such as beckmannia syzigachne, alopecurus japonicus and broad weeds such as chickweed and cleavers, reducing the using amount of the active ingredients, reducing the using cost and further reducing the environmental pollution, and simultaneously has the advantages of being wide in using period, being long in acting period and being safe for afterreap crops.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a herbicidal composition whose active ingredients are florasulam, methosulam and fluroxyfen. Background technique [0002] Wheat is a gramineous plant widely planted all over the world. It originated in the Middle East and is the second largest food crop in the world, second only to corn. In my country, wheat has a planting history of more than 5,000 years, and the planting area is extensive. From south to north, from plains to mountainous areas, wheat is cultivated in almost all agricultural areas. The planting area and total output of wheat in my country are second only to rice, ranking second in my country's grain crops. Wheat is the most important food crop in northern my country, with an annual planting area of ​​25 million hectares, mainly concentrated in the Huanghuaihai Plain and the Yangtze River Basin. [0003] There have always been a large number of weeds in wh...
