DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a Bacillus Thuringiensis (hereinafter referred to as B)
The present invention relates to a granular pesticide formulation containing a product derived from T. bacterium), a method for producing and using the same, and the like.

[0002]

BACKGROUND ART BT bacteria are Gram-positive soil bacteria and produce a toxin protein called δ-endotoxin during the sporulation stage. Since insects, especially lepidopterous larvae, die when this protein is consumed, pesticides using pesticide preparations containing BT bacteria products (hereinafter also referred to as BT agents) have been developed and sold (see: US Patent 3071
519, JP-A-3-27307, JP-A-4-32161
2 etc.). As another application, application to a plant growth agent has been reported (Japanese Patent Application Laid-Open No. 6-172116). Since BT agents are generally water-insoluble, their application requires special techniques, and many of them have been provided as suspending agents or wettable powders (eg, Vasilex wettable powder (registered trademark, Shionogi)). ). However, since a suspending agent uses a container such as a glass bottle or a plastic bottle, there are problems such as safety in transportation and storage, and further disposal of the packaging container. The wettable powder is
There is a problem of powdering at the time of measurement or preparation of drugs,
In addition, since it is in the form of a powder, it has disadvantages such as lack of fluidity and difficulty in accurate measurement. Therefore, in recent years, granular pesticide preparations such as wettable powders and granules (hereinafter, referred to as BT granular pesticide preparations) have attracted attention as BT agents from the viewpoints of storage stability, ease of handling, and the like. Developed products include Zentari granule wettable powder (TMI-921, Tomen), NN-9401, 9402 granule wettable powder (Hodogaya Contract Traho Co., Ltd.), Esmarck DF (Sumitomo Chemical), SB-7231 granule hydrate Agents (STD Biotech) and the like are known. In general, granular pesticide formulations of pesticides, especially in wettable powders, for the purpose of improving their dispersibility and susceptibility,
It is known to use ammonium sulfate, sucrose and the like (eg, JP-A-51-1649, JP-A-6-92803,
JP-A-10-218704). As a suspension of BT bacteria, an example in which ammonium sulfate is added is also known (JP-A-3-27307). However, no examples have been reported in which these components are blended in a granular pesticide preparation of BT bacteria.

Examples of the saccharides include monosaccharides (eg, glucose, galactose, etc.), disaccharides (eg, sucrose, lactose, sucrose, etc.), polysaccharides (eg, starch, etc.), but disaccharides are preferred. In particular, sucrose is preferred. The saccharide content is about 2 to about 80%, preferably about 5 to about 40%, more preferably about 10 to about 35%, based on the total weight of the formulation. If the content is too large, the formulation will be too low in the content of the pesticidal active ingredient, and if it is too small, the effect of enhancing the original dispersibility will be low, and it is not preferable in any case. In another preferred embodiment, inorganic salts and / or

A more preferred content of ammonium sulfate and sucrose is from about 10 to about 35%, based on the total weight of the formulation, whether only one or both are included. In the present preparation, the dispersibility, suspension property and / or hydration property and the like are remarkably improved by adding the above-mentioned inorganic salts and / or saccharides, as compared with the case where a clay or the like which has been frequently used as a bulking agent is used. Turned out to be.

[0008] The formulation preferably further comprises one or more surfactants. By appropriately adjusting the type, content, and the like of the surfactant, the dispersibility, suspension property, and / or hydration property of the preparation can be further improved. As the surfactant, various types of surfactants (e.g., nonionic, anionic, cationic, amphoteric types) generally used in agricultural chemical formulations are used, and preferably, nonionic or nonionic surfactants are used.

The content of the surfactant is about 1 to about 40%, preferably about 8 to about 3%, based on the total weight of the preparation.
0%, more preferably about 10 to about 25%. If the content is too large, not only will economic efficiency be lost but also sometimes dispersibility
Since there is a possibility that the preparation may have poor suspension properties, and if the amount is too small, the preparation may have poor dispersibility and suspension properties.

It can be prepared by sizing, drying, etc. by a method. Preferably,
It is a spray drying method or a fluidized bed granulation method, and in particular, the fluidized bed granulation method is particularly preferable in terms of obtaining better dispersibility, ease of adjusting the particle size, and the like. The amount of water used in preparing the slurry for spray drying is usually about 80 to about 300%, preferably about 100 to about 200%, based on the total weight of the solid components of the preparation. If too much water is used, spherical granules with a small wall thickness will be formed, resulting in low strength, so that not only will the formulation be concerned about powdering during transportation, but also the amount of water evaporation required per yield Resulting in a formulation with low energy efficiency. On the other hand, if the amount of water used is too small, the slurry becomes highly viscous and does not form a mist even when sprayed. In a more preferred example of the present formulation, when the physical properties of a water dispersible granule are evaluated by the measurement method described in the following Examples or a method similar thereto, the dispersibility is 30.
At most, the suspension is 70% or more, preferably 80% or more and / or the hydration is less than 1 minute. These physical properties are
Suitable for practical use as pesticides. When this formulation is used as a wettable powder for granules, it is sprayed on farmland as a spray liquid by stirring in water. The dilution degree in water is usually about 500 to 2000 times, preferably about 1000 times, in terms of weight.
