Description

Granular pesticide composition and spraying method thereof

The present invention relates to a granular pesticide composition and a pesticide spraying method for applying the granular pesticide composition to agricultural land using a power spreader mounted on an aircraft such as an unmanned aerial vehicle.

The pesticide composition used in the existing non-nons is generally granules, powders, emulsions, wettable powders, and liquids. In this agrochemical composition, granules and powders have been directly sprayed without dilution in water at 1 to 4 kg per 10a.

Recently, energy saving of pesticide spraying has been claimed, and it has become possible to reduce the spraying amount or throw it in the paddy field without entering the paddy field ( Patent Document 1, Non-Patent Document 1). In addition, in recent years, as a more advanced energy saving method, spraying using aircraft such as unmanned helicopters and unmanned aerial vehicles is also being considered.

However, when spraying using an aircraft, a power spreader is required because the granular pesticide composition must be blown away. This power spreader has an impeller with wings, and when the granular pesticide composition collides with the blades of the impeller, since the granular pesticide is strongly hit, the granular pesticide composition with low strength is crushed. The differentiated chemical drifts in the air, and the pesticide is exposed as a worker or weakened by the crops in the adjacent area, causing so-called drift. In addition, when the granular pesticide composition is a water-spreading granular agrochemical composition, the crushed and small granular pesticide composition will immediately complete disintegration when it falls to the water surface, so there is a possibility that the desired self-diffusion property cannot be exhibited.

Because of such circumstances, it is an important subject to increase the hardness of the granular pesticide composition and to make it difficult to differentiate in the granular pesticide composition to be sprayed in the air with a power spreader.

Accordingly, an object of the present invention is to provide a granular agrochemical composition that does not cause drift during aerial spraying with a power spreader by increasing the hardness of the granular agrochemical composition and making it difficult to differentiate.

As a result of intensive research to solve the above problems, the present inventors have found that the above problems can be solved by containing an organic hollow body and an inorganic hollow body in a specific amount in a granular agrochemical composition containing an agrochemical active ingredient, and the present invention was completed.

That is, the present invention is a granular pesticide composition comprising 0.1 to 70 parts by mass of an agrochemical active ingredient, 0.3 to 15 parts by mass of an organic hollow body, and 0.01 to 9.99 parts by mass of an inorganic hollow body per 100 parts by mass.

In addition, the present invention is a spraying method of agrochemicals, characterized in that the application of the granular agrochemical composition to farmland using a power spreader.

In addition, the present invention relates to kneading, granulating, and sizing a mixture containing 0.1 to 70 parts by mass of an agrochemical active ingredient per 100 parts by mass, 0.3 to 15 parts by mass of an organic hollow body, and 0.01 to 9.99 parts by mass of an inorganic hollow body per 100 parts by mass.粒) is a method for producing a granular pesticide composition, characterized in that after drying.

Furthermore, the present invention relates to a granular agrochemical composition containing 0.1 to 70 parts by mass of an agrochemical active ingredient per 100 parts by mass, 0.3 to 15 parts by mass of organic hollow bodies and 0.01 to 9. It is a method for inhibiting differentiation of a granular agrochemical composition characterized by containing 99 parts by mass of an inorganic hollow body.

The granular agrochemical composition of the present invention has high hardness and is difficult to differentiate. Therefore, the granular agrochemical composition of the present invention is very suitable for application to agricultural land using a power spreader mounted on an aircraft, such as an unmanned aerial vehicle, as well as normal spraying.

The granular pesticide composition of the present invention (hereinafter referred to as "the present invention composition") contains 0.1 to 70 parts by mass of an agrochemical active ingredient per 100 parts by mass, 0.3 to 15 parts by mass of organic hollow bodies, and 0.01 to 9.99 parts by mass of inorganic hollow bodies. will do

Although the composition of the present invention may be applied to farmland according to a conventional method, it is preferable to apply the composition to farmland such as paddy fields in a fresh water state, for example, using a power spreader in particular, because it has the above properties. When applied to agricultural land, the amount of the composition of the present invention is 50 to 500 g, preferably 200 to 400 g per 10a of agricultural land.

The power spreader used for the said application is not specifically limited, For example, a back load-type power spreader, a rice planting simultaneous spreader, an impeller-type granular spreader, etc. are mentioned. It is preferable that the powered spreader be mounted on an aircraft and spray from the air. The aircraft is not particularly limited, and for example, fixed-wing aircraft such as Cessnagi and small light aircraft, rotary wings such as manned helicopters and unmanned helicopters, tilt-rotor aircraft that have both features, and motors and batteries developed by unmanned helicopters. and agricultural multi-rotor machines (so-called drones) that are driven. Among these aircraft, small unmanned helicopters and unmanned aerial vehicles specialized for pesticide spraying applications are preferable, and drones are particularly preferable.

This unmanned aerial vehicle is smaller than a known unmanned helicopter equipped with an internal combustion engine, and small rotation is advantageous, and precise maneuvering is possible. Because of its characteristics, it is suitable for small and medium-sized pavements, middle mountainous areas, pesticide spraying in urban areas, etc., but on the other hand, the loadable weight is small. Therefore, it is preferable that the pesticide composition sprayed by the drone is a so-called simplified formulation with a small amount of spray required per unit area. The composition of the present invention meets the requirements of the agrochemical composition to be sprayed from such a drone. In particular, the water-diffusing granular pesticide composition in the composition of the present invention is suitable for special drone spraying.

When the shutter is opened when spraying pesticides, the composition of the present invention from the tank falls through the hopper by its own weight to the discharge unit, collides with the rotating blades of the impeller, and the force of orbiting in the discharge unit in the same direction as the self-rotation of the impeller is given, and is ultimately discharged from the discharge port to the outside of the power disperser by centrifugal force. Although pulverization and differentiation by collision with the impeller can occur even in ordinary agrochemical granules, the composition of the present invention has a particle size distribution of 80% or more with a particle diameter of 3 mm or more. it's difficult.

In addition, since "dispersion type" or "air spraying" and "unmanned helicopter spraying" are registered as pesticides as a method of use in Japan, the method of use of the composition of the present invention can be described on the pesticide label.
