題である。However, the storage stability of these packaged pesticide formulations is not always sufficient.
Depending on the type of pesticide wettable powder contained, gas is generated during storage, resulting in expansion of the package and sometimes rupture. Further, increasing the solubility and dispersibility of a packaged agricultural chemical formulation in water is also an important issue in putting the packaged agricultural chemical formulation into practical use.

産できる。The holes formed in the water-soluble base material have a size such that a gas can pass through but a pesticide wettable powder or granular wettable powder contained therein cannot substantially pass through. Generally, the size of one hole is 0.000, although it depends on the particle size of the wettable powder.
It is about 1 to 1 mm 2 , preferably about 0.0002 to 0.5 mm 2 . There may be one or more holes per package, and the holes may be opened before or after the pesticide wettable powder or the granular wettable powder is packed. Furthermore, when heat-sealing and packaging the water-soluble polymer film,
A hole may be provided by sandwiching a thread or string during heat sealing. When industrially producing the packaged pesticide formulation of the present invention in a large amount, for example, with a machine for packaging the pesticide formulation by heat sealing, a plate with about 1 to 10 needles before, during or after heat sealing. Alternatively, it can be efficiently produced by a method of pressing the rotating cylinder against the water-soluble base material.

施用される。Since the packaged pesticide formulation of the present invention breaks when wet with water, it is generally preferable to package it with a water-insoluble base material when storing it. That is, polyethylene,
Sheets and containers of polypropylene, polystyrene, polyester, polyamide, cellophane, polyvinyl chloride, polyvinylidene chloride, acrylonitrile butadiene styrene, acrylonitrile styrene, vinylidene fluoride, polytetrafluoroethylene, polycarbonate, polyacetal, aluminum, paper, etc. The packaging pesticide formulation of the present invention is further packaged. In particular, a polyethylene or polypropylene heat seal material is attached to the interior of the aluminum sheet, or a moisture-proof composite aluminum bag in which a sheet material such as paper, cellophane, polyester, or polyamide is attached to the exterior of the aluminum sheet. It is preferable to further package the pesticide formulation. These water-insoluble packaging base materials are preferably provided with holes through which gas can pass. At this time, holes may be provided by a method of sandwiching a thread or a string in a portion where the sheet materials are bonded by heat sealing or the like. The packaged agrochemical formulation of the present invention is applied by diluting it with water at an appropriate ratio in the same manner as an ordinary agrochemical wettable powder or granular wettable powder.
