Aqueous suspension pesticide composition

Technical field

[0001] The present invention comprises an agrochemical active ingredient, water, rosin, and a lignin sulfonate having a weight average molecular weight of 20,000 or less, which suppresses the particle growth of the agrochemical active ingredient and has a high temperature. It relates to an aqueous suspension pesticide composition having good storage stability. Background art

[0002] In the case of an aqueous suspension pesticide composition, particles of the pesticidal active ingredient are suspended in water, so that the particle growth of the pesticidal active ingredient occurs due to recrystallization during storage, leading to a decrease in biological activity. There is.

As a means for preventing or suppressing the particle growth of the agrochemical active ingredient, a method of blending fats such as petroleum fats, coumarone fats, and ester gums (for example, see Patent Documents 1 and 2) is known. Depending on the type of agrochemical active ingredient and storage conditions, particle growth may not be sufficiently suppressed. It is also known about the problem that these oils soften during storage at high temperatures and the fluidity of the composition is poor.

BEST MODE FOR CARRYING OUT THE INVENTION

[0007] The resin used in the present invention is not particularly limited, but is preferably solid at room temperature. More preferred are rosin derivatives such as rosin glycerin ester, rosin pentaerythritol ester, polyoxyethylene polystyryl ether-rosin, and more preferred are rosin glycerin ester. These coffins can be used alone or in admixture of two or more, and the ratio in the case of mixing can be freely selected. The content of the resin in the composition of the present invention can be appropriately selected, but is preferably in the range of 0.1 to 5.0 parts by weight with respect to 100 parts by weight of the composition of the present invention.

[0008] The lignin sulfonate used in the present invention is not particularly limited as long as it has a weight average molecular weight of 20,000 or less. The salt is not particularly limited, and examples thereof include alkali metal salts (such as lithium salt, sodium salt and potassium salt) and alkaline earth metal salts (such as calcium salt and magnesium salt). Specific examples include PolyfonH (weight average molecular weight: 4300, manufactured by MeadWestvaco), Reax85A (weight average molecular weight: 13200, manufactured by MeadWestvaco), ReaxlOOM (weight average molecular weight: 2000, manufactured by MeadWestvaco). The weight-average molecular weight of ligne sulfonate is a value measured by GPC (Gel Permeation Chromatography). In the present invention, a lignin sulfonate having a weight average molecular weight of 20,000 or less and a lignin sulfonate having a weight average molecular weight exceeding 20,000 may be used in combination. However, if the pesticidal active ingredient is one or more selected from the group consisting of acrylonitrile compounds, spiromesifen, spirodiclofen, pyridaben and phenoxypropionic acid compounds, the weight average molecular weight is 20, It is not always necessary to use less than 000 lignite sulfonates.
