Abstract

Abstract New suspension concentrates of plant protection agents consisting of an insoluble or sparingly soluble pesticide having a melting point of > 40°C, a phospholipid and an organic solvent or solvent mixture from the alcohol or ether group, and processes for the preparation of these concentrates by grinding in colloid, ball, sand, stirred or grinding ball mills.

Description

~ ~ ~9 ~L~ ~

The present ;nvention relates to new suspension concentrates which, in addition to an insoluble or spar-ingly soluble pestic;de, contain a phospholipid and a physiologically acceptable solvent or solvent mixture from the alcohol or ether ~roup9 and to their preparation.
The use of plant protection a~ents for reducin0 losses in harvests due to diseases, pests and weeds can to-day no longer be avoided in agriculture. Mos~ plant protec tion agents are ~atRr-;nsoluble or very sparingly solub~e in wa~er and must therefore be used in very d;lute concen trat;on as a wettable powder or emulsion concentrate.
Because of the more favourable dosage, powder or granule forms of emulsion concentrates are preferred in agriculture. In use, the emulsion concentrates are emul-sified in ~ater and appl;ed as so-called spray liquors.
Spray liquors are generally prepared from emulsion concentrates of water-;nsoluble active compounds, ~hich concentrates are anhydrous or have a low ~ater content.
The emulsion concentrates contain about 10 40X of the active compounds, and ;n addit;on organic solvents and emulsifiers and other 3UXi liaries, such as stab;lisers, furth~r wetting agents~ anti foaming agents and the like.
To prepare the emulsion concentrates of these water-;nsoluble ac~ive rompoundsD the active compounds are dissolved in a sui~able organic solven~, such 35 alkyl~
benzenes, acetone, kerosene, toluene and the like, and a suitable emulsifier or, in most cases, mixtures of such &~3~

emulsif;ers are added. The emulsifiers used are prefer-ably ~nionic~ cationic or non-ionic emuLsifiers or mix-~ures of these emulsifiers. Many wett;ng agents and emul-sif;ers can greatly ;nterfere w;th the osmo~is and water balance of plantsD so that the plants treated are damaged.
Moreover, the solvents used are ;n most cases toxic them-seLves, and can pollute the environment.
If a spray liquor is used9 the corresponding con-centrates should emuls;fy spontaneously. The emulsion formed should be sufficiently stable that no ;rreversible de-mixing phenomena are observed e~en ~hen the emulsion is left to stand for several ~ours. No stabLe foam should forn when the emuls;on ;s st;rred or pumped~ The require-~ents cf an ;deal spray l;cuor are, for example, the for-mation of a continuous f;l~ of act;ve compound with good adhes;on or wett;ng on the plant to be protected, and a high res;stance to being ~3shed ~ff by rain or other ~eather influences. Furthermore~ accelerated penetration of the active compound into the plant should be ensured.
Howe~er, most pest;cides are not only sparingly soluble or insoluble in ~ater, but also insoluble in the solvents acceptable for agriculture. Such agents can be used only as granules or wettable powders. When used in practice, difficwlties arise in exact dosing and appl;ca-t;on. It is therefore desirable also to have a liqu;d form for these act;ve compouncls~
It has now been found, surprisingly, that stable suspension concentrates of plant protection agents are obtained if insoluble or sparingly soluble pesticides are 93~

ground as a mixture with certain phospholipids in the presence of a physiologically acceptable solvent or solvent mixture from the alcohol or ethex group.
~he new suspension concentrates are distinguished by the fact that the active compound is present in finely divided form in a very finely ground form of average particle size less than or equal to 1 ~I, as a result of the addition of the phospholipids. The new suspension concentrates have a high storage stability.
Thu~, according to one aspect of the invention there is provided suspension concentrates of plant protection agents based on an insoluble or sparingly soluble pesticide, a phospholipid and an organic solvent or solvent mixture, characterised in that the concentrate consists of a) lS - 35% by weight of an insOluble or sparingly soluble pesticide having a mel~ing point of ~40~C an~ a mean particle size of c 1~ , b) 15 - 35~
by weight of a phospholipid selected from the group comprising phosphatidylcholine, phosphatidylethanol-amine, N-acylphosphatidylethanolamine, phosphatidylino-si~ol, phosphatidylserine, lysolecithin, phosphatidyl-glycerol, hydrogenated phospholipids and mixtures thereof, and c) 40 - 60% by weight of a solvent or solvent mixture from the alcohol or ether group.
According to another aspect of the invention there is provided a process for the preparation of 3~
- 3a -suspension concentrates of plant protection agents characterised in that a mixture of a) 15 - 35% by weight of an insoluble or sparingly soluble pesticide having a melting point of ~ ~0C; b~ 15 - 35~ by weight of phospholipid selected from the group com-prising phosphatidylcholine, phosphatidylethanolamine, N-acylphosphatidylethanolamine~ phosphatidylinositol, phosphatidylserine, lysolecithin, phosphatidylglycerol, hydrogenated phospholipids and mixtures thereof, and c) 40 - 60% by weight of a solvent or solvent mixture from ~he alcohol or ether group, is ground together in a collid, ball, sand, stirred or grinding ball mill at 20 - 50C for 10 - 60 minutes so that the parti d e si~e of the insoluble or sparingly soluble pesticide is < 1~ .
Atten~ion is directed ~o our co-pending Canadian patent applications serial numbers 431,955 and 431,956 which claim embodiments of the invention disclosed in this application.
When spray liquors obtained from these con-centrates with water are used, the new compositions spontaneously form suspensions. The suspensions formed are very stable and display no irreversible demixing phenomena even on relatively long storage. When applied, the spray liquors produce a continuous film of active compound with good adhesion and wetting on the parts of the plants to be protected. Moreover, accelerated pene-tration into the plant is ensured. They also display a ;?o~
- 3b -high resistance to being washed off by rain or other weather influences. In addition, as ubiquitous compo-nents of living material, the phospholipids are completely non-toxic and are no threat to ecological equilibrium.

To prepare these ne~ suspension concentra~es~ ~he insoluble or spar;ngly soluble pestici des are mixed with a phospholipid or phospholipid mixture and the mixture is ground in th~ presence of an organic solvent or solvent mixture from the alcohol or ether group~ in particular in the mixing proportions of 15 - 35X of pesticide, 15 - 35X
of phosphvlipid and 40 - 60X of solYent9 in colloid, ball, sand, stirred or grinding ball mills at 20 - 50C, prefer-abLy continuously, for 10 - 60 minutes, in particular 10 -30 minutes. It is not necessary to add other auxiliaries.
Stable suspension con~entrates with a mean particle size of ~1 ~ are obtained.
Examples of possible phospholipids are the co~mer~
cially available phosphatidylcholines or phosphatidyl-15 choline mixed products~ such as, for example, PhospholiponR 25 (ZSX of phosphatidylcholine, 25X of phosphatidylethanolamine and 2U% of phosphatidylinositol), Phospholipon 38 (38% of phosphatidylcholine, 16% of N-acetyl -phosphatidyle'hanol amine, 4~ of pho~phatidylethanolamine), 3~gL

Phosphol;ponR 55 (55X of phosphat;dylcholine, 25X of phosphatidylethanolamine and 2X of phosphatidylinosi~oL), Phosphol;ponR 80 ~80X of phosphatidylcholine and 10% of phosphatidylethanolamine), Phosphol;ponR 100 t96X of phosphatidylchol;ne~ and Phosphol;ponR 100H t96% of hydrogenated phosphat;dyl-choline).

2 - 5 carbon atoms or saturated or monoolef;n;cally un-saturated fatty acids with 14, 16, 18 or 20 carbon atoms~
