Abstract

PURPOSE:The titled wettable powder having a little deterioration with time of active ingredients and improved stability, showing hardly deterioration of characteristics with time, obtained by blending a wettable powder consisting of an organophosphorus agriculatural chemical active ingredient and a carbamate agricultural chemical active ingredient with sodium tripolyphosphate. CONSTITUTION:A wettable powder consisting of an organophosphorus agricultural chemical active ingredient[e.g., 0,0-dimethyl-0-(3-methyl-4-nitrophenyl) phosphorothioate, etc] and a carbamate agricultural active ingredient (e.g., 1-naphthyl N-methylacarbamate, etc.) is blended with sodium tripolyphosphate to give a wettable powder. The amount of sodium tripolyphosphate is 0.5- 10wt%.

Description

DETAILED DESCRIPTION OF THE INVENTION This product #4#i is related to the new Arashi Nomaro's Honwado, and in detail, W phosphorus-based pesticide active ingredients, carbamate-based pesticide active ingredients, and water before meals. s#IK,) Regarding the hydrating agent for agricultural roofing that contains 41w1 of lipolysium, it has been found that active ingredients of organic phosphorus pesticides, such as thiophosphoric acid esters, have been used as SOW. It is highly effective against Meite Tamarisen, which is a type of fish, but it is less effective against planthoppers and W Kobaishin, which are sagging at 11 F4 hours.On the other hand, carbamate type i

However, it is extremely effective against 2M Copai a.

The insecticidal effect against Mayte-breathing species is poor, so KN
Machine #I type aS active ingredient, carbamate type pesticide active ingredient and Oa agent oili use are widely used.As a base agent for this one combination, powder and emulsion are mostly used. ,
It is rarely used as a hydrating agent, and its origin is that of a hydrating agent. The threshold m at which this O hydrating agent causes agglomeration when diluted with water is 4), so it was very difficult to make this hydrating agent. It is known that 41% V% is a phenomenon that occurs when agricultural chemicals are mixed with carbamate IIi drugs.

In the case of an emulsion, this I&1III is attacked by selecting and feeding a special S shield and a special #jii active I@, and the effective amount of the pesticide is determined and the amount of food is determined, Moreover, 4HO can be put to practical use within a very narrow range of thermal stability.
Hiro existence corner.

However, in the case of wettable powders, the problems of aging of the active ingredients during storage and the threshold of soap collection in the spray solution cannot be solved, as mentioned above. %I1%AO is maple-shaped, so-called made-to-order me is done to meet the needs just before use as a temporary measure. In this case, the active ingredient content, am
Although the physical properties are satisfied, the active ingredient content O decreases over time.
Cutting ability O deterioration is avoided, and ζ0r14 is also the main cause of decreasing effectiveness in practical situations and backing up of effectiveness.

The present inventors have solved the above-mentioned drawbacks, and have created an excellent water conservancy that has good s property and excellent stability with very little change over time of organic scale II & drug t II i properties and carbamate pesticide active ingredients. KIIt was successful.

The present invention is an organic phosphorus layer asi* and a carbamate pesticide active ingredient! This article relates to a hydrating powder with excellent stability, which is a bulking agent depending on the IK, and an II #mold.

According to the present invention, the organic phosphorus pesticide active ingredient is, for example, 0.

There is an upper limit of 1j! Of these, one or more organic phosphorus-based agricultural chemical active ingredients may be used, and one or more carbamate-based agricultural chemical active ingredients may also be used.

As a surfactant, use 1 part dispersing agent, such as polyallyl ether in diethylene alcohol, and 1 part dispersant! ! Use it!
Depending on the situation, isopropyl acetate, dophos 710, and 710, and 1s-s, 6, and 710, etc. are most preferred. O Yangsha less than aSS has a small effect, and if it is more than 1.5, it will decompose the pesticide active compound and become desirable.

On the other hand, O salts other than Tripoli scales) - for example, malic acid sodium, citric acid no. Charcoal sorter, charcoal soda powder, etc. During storage, the effectiveness of the hydrating agent varies over time, and the effect of preventing agglomeration and dispersion is 0, but it is not sufficient at tk%0.

In addition to the 8th aspect of the present invention, it is known that tripolyphosphate is added to the formulation in the formulation. There is a technique to promote the elution of active ingredients after spraying.

119. Temperature control is achieved by adding poly(9) acid salt as an auxiliary ingredient to the aqueous dispersion of Teabe 7 Dal, which is a liquid to be sprayed on the surface of fruits.
