The present invention provides 1-(α,α-dimethylbenzyl)-3
-(paratolyl) urea (hereinafter referred to as Daimeron)
The invention relates to improved formulations of herbicides containing as active ingredients. Daimeron is generally well known to be effective as a herbicide with a unique action of strongly acting selectively on Cyperaceae plants when treated with soil. While studying herbicidal granules containing Daimeron as an active ingredient and carriers such as bentonite, talc, clay, etc., the present inventors discovered that this agent changes significantly over time. As a result of various studies to solve this problem, it was discovered that the decomposition of Daimeron can be suppressed by adding an ethylene oxide adduct type nonionic surfactant. The present invention is based on this new knowledge. Here, the ethylene oxide adduct type nonionic surfactant is a compound having the general formula -(OCH 2 CH) o - in the molecule, and preferred examples thereof include polyoxyethylene nonyl phenol ether, polyoxyethylene lauryl ether, Examples include polyoxyethylene higher alcohol ether, polyoxyethylene sorbitan monolaurate, polyethylene glycol monolaurate, and polyoxyethylene alkylamine. The present invention provides a shape that can be adopted by Daimron herbicide,
For example, it is applied to prevent the decomposition of Daimeron when it is used as a herbicide by mixing Daimeron with a mineral carrier, such as granules, fine granules, and wettable powders. The mineral carrier here may be one commonly used in this technical field, and suitable carrier materials include clay minerals such as bentonite, talc, clay, diatomaceous earth, zeolite, acid clay white carbon, and the like. Further, the formulation method may be according to a method commonly used in this technical field. In addition, in the present invention, as long as it does not impede the purpose of the present invention,
Furthermore, natural products, additives, wetting agents, dispersants, binders, other types of herbicides, fungicides, insecticides, fertilizers, etc. may be incorporated. The amount of the above-mentioned stabilizer added varies depending on the amount of the active ingredient, type of carrier, dosage form, etc., but in general, when considering other properties that the product should have, 0.1 weight of the stabilizer is added to the formulation. Parts to 5.0 parts by weight, preferably 0.5 parts to 2.0 parts by weight, provide practical stability. Next, some examples of the present invention will be shown, but the dosage form, additives, and amounts added of the present composition are not limited to these examples. After uniformly mixing and pulverizing with the blending ratio shown in the example, adding water and kneading, 0.7 mm
After extrusion granulation using a φ screen, 1
Granules are obtained by drying for a period of time. After putting the granules into a glass bottle, sealing it tightly, and storing it in a thermostat at 50℃ for 30 days,
Dimeron in each sample was quantified to determine the decomposition rate (%). In addition. All proportions shown in the examples are parts by weight. Example 1 Daimron 7.4 parts Bentonite 35.0 Talc 56.6 Polyoxyethylene nonylphenol ether
