Embodiment 1

[0029] The emulsifiable concentrate containing diflufenicin and clomazone of the present embodiment, its component and weight content are as follows:

[0030] Diflufenamide 10%

[0031] Clomazone 20%

[0032] Surfactant 9%

[0033] Other functional additives 1%

[0034] Solvent 60%

[0035] The surfactant is a mixture of emulsifier, dispersant and wetting agent. The emulsifier is Nongru 33#, with a content of 5%, the dispersant is calcium lignosulfonate, with a content of 3%; the wetting agent is sodium lauryl sulfate, with a content of 1%; other functional additives are ethylene glycol; The solvent is propanol.

[0036] The production method of the emulsifiable concentrate containing diflufenicin and clomazone in this embodiment is as follows: in accordance with the above weight content, the active ingredients diflufenicin and clomazone are added to the solvent, and surfactants and clomazone are added therein. For other functional additives, just stir and mix evenly in ...

Embodiment 2

[0038] The difference between the present embodiment and embodiment 1 is that each component and weight content are as follows:

[0039] Diflufenamide 5%

[0040] Clomazone 15%

[0041] Surfactant 9%

[0042] Other functional additives 6%

[0043] Solvent 65%

[0044] The surfactant is a mixture of emulsifier Nongru 500# and Nongru 600#, the dosages are 4% and 5% respectively; other functional additives are urea; the solvent is butanol. .

Embodiment 3

[0046] The difference between the present embodiment and embodiment 1 is that each component and weight content are as follows:

[0047] Diflufenamide 10%

[0048] Clomazone 25%

[0049] Surfactant 7%

[0050] Other functional additives 3%

[0051] Solvent 55%

[0052] The surfactant is a mixture of emulsifier Nongru 500# and Nongru 600#, the dosages are 4% and 5% respectively; other functional additives are propylene glycol; the solvent is diethylene glycol.

[0053] Below use embodiment 2, embodiment 3 and comparative example to carry out field efficacy test for garlic field weeds, to better illustrate the beneficial effect of the present invention, test result is shown in table 1 below. Comparative example 1: 50% difluorfen wettable powder; Comparative example 2: 48% clomazone emulsifiable concentrate.

Abstract

The invention belongs to the field of agricultural weedicides, and particularly relates to diflufenican / clomazone cream. The diflufenican / clomazone cream comprises the following components in percentage by weight: 1-20% of diflufenican, 1-60% of clomazone, 5-20% of surfactant, 0-10% of other functional assistants and 10-80% of solvent, wherein the sum of weight percents of all the components is 100%. The composition provided by the invention is mainly used for controlling annual broadleaf weeds, grassy weeds and the like in garlic fields, wheat fields and paddy fields. The composition has the characteristics of effect improvement, weed control spectrum widening, drug resistance delaying and low cost.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to an emulsifiable concentrate containing diflufenican and clomazone. Background technique [0002] Diflufenican belongs to carotenoid biosynthesis inhibitors and is a broad-spectrum selective wheat field herbicide, which causes chlorophyll damage, cell rupture, and plant death. Apply 125-250g / ha pre-emergence or post-emergence to wheat and barley fields in autumn to control gramineous and broad-leaved weeds, especially weeds such as pig's weeds, porcini and viola. The agent has the following characteristics: wide herbicide spectrum; can control malignant weeds; long efficacy period in the soil; stable efficacy; can be mixed with other herbicides to expand the herbicide spectrum. [0003] Clomazone, also known as clomazone, is a selective pre-emergence herbicide. It is mainly absorbed through the roots and young shoots of plants, transported upwards, diffuses to leaves throug...
