Abstract

PURPOSE:A flow dust that contains active ingredients of agricultural chemicals, a carrier of mineral powder and saccharides selected from monosaccharides, oligosaccharides, polysaccharides, saccharide alcohols, acidic saccharides and aminosaccharides, thus preventing the dust from flying again when human bodies come in contact with the crops. CONSTITUTION:The titled dust (flow dust) contains active ingredients of agricultural chemicals, such as insecticide, fungicide, or plant growth regulator, a mineral powder carrier and a saccharide, thus having an average particle size of less than 5mic and an apparent specific gravity of less than 0.15. The saccharide is at least one selected from monosaccharides, oligosaccharides, polysaccharides, saccharide alcohols, acidic saccharides, and aminosaccharides and the amount added to the dust is preferably 0.1-5wt%. The incorporation of the saccharide completely inhibits the resultant dust from flying up again from the crops and the sprayers can carryout operation safely.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a technique for improving a fine powder for greenhouse horticulture (hereinafter referred to as flow dust). That is, the present invention is a fine powder for greenhouse horticulture that is composed of a highly active medicinal ingredient and a mineral powder carrier, has an average particle size of 5 microns or more, and has an apparent specific gravity of 0.15 or less, and is capable of containing monosaccharides. , oligosaccharides, polysaccharides, sugar alcohols, acidic saccharides, and amine saccharides.This invention relates to an improved fine powder for greenhouse horticulture, characterized in that it contains at least one kind of saccharide selected from , oligosaccharides, polysaccharides, sugar alcohols, acidic saccharides, and amine saccharides.The purpose and The reason for this is that whenever one of the sugars listed in 1- is added to conventional flow dust, the finely powdered flow dust attached to the crop body! An object of the present invention is to provide flow dust which is improved so as to prevent plant debris from falling back into the air due to contact with the plant.

In recent years, with the development of greenhouse horticulture, 300 to 500 g of fine powder per 10 ares has been added to the outside of a vinyl or glass greenhouse (greenhouse: simply referred to as a greenhouse).
A spraying floatast was developed.
490 Publication 1jQ).

Flodus (・) is a fine powder with an average particle size of 5 microns or less and an apparent specific gravity of 0.15 or less.This Flowdust is a fine powder agent that has an average particle size of 5 microns or less and an apparent specific gravity of 0.15 or less. The design is such that the chemical flows rapidly into the air for a certain period of time, falls into the greenhouse, and is deposited evenly on the crops.Therefore, the sprayer sprays the chemical from outside the greenhouse in the evening. Safety instructions are given to enter the greenhouse and work on it the next morning after the chemicals have finished falling.However, when the sprayer enters the greenhouse the next morning to work, the chemicals floating in the air must be removed. However, the reality is that when people come into contact with crops, the adhering chemicals are raised again, which comes in contact with the sprayer and poses a health and safety problem. No countermeasures have been taken against this.

The present inventors conducted various studies in order to develop a formulation that suppresses flow dust from rising again. As a result, we found that by blending the above-mentioned additives into conventional flow dust, it was possible to almost completely suppress the recurrence of chemicals from above the crop, without impairing the properties of flow dust at all. The present invention has now been completed. In other words, it is possible to suppress the spread of chemicals from one crop without compromising the high floatability that is the most important feature of Flow Dust, and it has become possible for scatterers to work safely. This is a major feature of the present invention. Furthermore, since the saccharide used in the present invention is highly water-soluble, it has the characteristic that even if a drug is attached to harvested crops, it can be easily washed with water.

Examples of the additives that can be used in the present invention include primary additives. However, those that can be used in the present invention are not limited to the following examples.

All of the average particle diameters of Examples J2 were 1 to 3 microns, and the apparent specific gravity was 0.14 for Example 1 and 0.1 or less for the other Examples. Further, the flow dust used in the test example described in F was almost the same as these, and satisfied the requirements for flow dust.

Test examples are given below to prove the usefulness of the present invention.

Comparatives 1 to 9 were prepared by removing the additives from Examples 1 to 9 and replacing them with the same amount of white carbon.

Using a standard powder vomit tester, 5 g of the drug prepared according to the above example was sprinkled downward into a 1 m' box and left for 5 minutes. After that, particles scattered and suspended in r,+= were collected by absorption into a water supply pipe containing 75 mu of water for 1 minute at a rate of 30 μm/min. A111 was determined, and the buoyancy index was determined using the following formula.

Floatability index-100-transmittance (%) The results are shown in Table 1. Note that the larger the buoyancy index, the higher the buoyancy.

Go to the side again ■ ↓ 11th Tomato in a 1m' wooden frame (variety!!!: Kai-5th season)
Set up 4 pots and sprinkle 500g of the drug produced according to the above example with a mise-nto duster at a rate of /10 are! Speak. After the late Ifi, cut two pots of tomatoes from the base of the plant, place each in a polyethylene bag, add one portion of ion exchange water, and shake well. Next, after appropriately diluting this extract with ion-exchanged water, the transmittance at a wavelength of 610 mIL (
%).

The drug hole extracted from the flame test line obtained in advance with the same drug is calculated, and the average value (X) of the 2-poly drug return is determined. In addition, the remaining 2 and 7 plants were left in the greenhouse, and after one night of exposure, cut off the Toma I from the base of the plant and cut it under L (50 cm).
After shaking 10 times in water (for 1 second) and 10 times in water (50 cm for 1 second), place the bag in a polyethylene bag and repeat the same procedure as above to apply the extracted drug. Calculate and find the average value (Y') of the two drug-attached items,
The residual rate (%) was determined from the following equation.

Survival rate (%)--xto.

As a result, the higher the residual rate (%), the less the flow dust after spraying.

At the same time, when tomatoes were shaken horizontally under E using the above method, the state of powdering of the powder agent was observed with the naked eye, and the degree of powdering was ranked as follows.

In addition, the numbers in the Examples column indicate that the formulations were prepared and tested according to the above-mentioned Examples.

The results of this test are shown in Table 1.
