Description

[Detailed description of the invention]

The present invention relates to a novel herbicidal composition, a method for its production and its use. In order to reduce crop losses due to weeds and wild herbaceous plants when growing useful plants, it is now essential to use chemical weed control preparations (herbicides). A wide variety of chemicals have been used to control weeds and wild plants. However, there are still some unresolved problems with currently used herbicides. Chemical weed control agents often have to be used in high concentrations. As a result, it can become a source of toxic environmental pollution. The most important requirements that weed control preparations must meet are that they have the highest possible selectivity and activity against the target weeds and wild legumes, and have an effect on useful plants. It is the smallest and causes the least disturbance to the biological environment. The selectivity of herbicides must therefore meet strict requirements. To reduce environmental pollution, the amount of herbicide required per hectare to control weeds and wild herbs should be kept as low as possible, but this often results in a loss of activity. . Another requirement that must be met is ease of handling both during production and during application. It has now surprisingly been possible to combine a herbicidally active substance or a mixture of several herbicidally active substances with phosphatidylcholine, hydrogenated phosphatidylcholine,
Phospholipids selected from the group consisting of phosphatidylethanolamine, N-acylphosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, lysolecithin and phosphatidylglycerol, or several such species. When used in a weight ratio of 1:0.2 to 1:20 with a mixture of phospholipids of
It has been found that it can be reduced by ~60%, and in some cases by 80%, without any risk of damage or damage to useful plants. In addition to being extremely economical in terms of processing, the new herbicidal compositions have the particular advantage that their decomposition is accelerated in the useful plants, so that no herbicide remains in the useful plants at harvest time. has. Due to this rapid decomposition, waiting times (from weed control to harvest) can also be reduced. Finally, phospholipids are generally natural products, in any case non-toxic products, and due to their nature and properties do not cause any environmental pollution, nor do they have any disadvantages to the waiting time. It has no effect. Of course, some phospholipids are even used in food. To produce the novel herbicide composition, the herbicide and phospholipid are mixed in a weight ratio of 1:0.2 to 1:20;
Preferably they are mixed in a weight ratio of 1:0.5 to 1:10, and even more preferably in a weight ratio of 1:1 to 1:5. The weight of the phospholipid component is based on substantially pure phospholipid. Suitable phospholipids are, for example, commercially available phosphatidylcholines or phosphatidylcholine mixtures such as those described below. Phospholipon 25 (Phosphatidylcholine 25%, Phosphatidylethanolamine 25% and Phosphatidylinositol 20%) Phospholipon 55 (Phosphatidylcholine 55
%, Phosphatidylethanolamine 25% and Phosphatidylinositol 2%) Phospholipon 80 (Phosphatidylcholine 80%

%) Phospholipon 100H (Hydrogenated Phosphatidylcholine 96%) Phospholipon 38 (Phosphatidylcholine 38
%, N-acetylphosphatidylethanolamine 16% and phosphatidylethanolamine 4%). The method described in the specifications of West German Patent Nos. 1047597, 1053199, 1617679, and 1617680, and the specifications of West German Patent Application Publication No. 3047048, 3047012, or 3047011 Particular preference is given to using natural phosphatidylcholine, which can be produced by. Suitable N-acylphosphatidylethanolamines are in particular those derived from saturated or olefinically unsaturated fatty acids whose acyl group contains 2 to 20 carbon atoms, even more particularly 2 to 5 carbon atoms. From saturated fatty acids containing or 14, 16, 18 or 20
These are those obtained from monoolefinic unsaturated fatty acids containing 1,000 carbon atoms. Virtually any herbicide can be used as a herbicide. It is therefore possible to use compounds selected from the group consisting of photosynthesis inhibitors, respiratory inhibitors, growth promoters, milose inhibitors and germination inhibitors. Particularly suitable examples are described below. 1 General formula [In the formula, (a) R ₁ , R ₂ and R ₃ are the same or different and represent hydrogen, methyl or halogen, especially chlorine, provided that at most two groups represent hydrogen, and R ₄ is hydrogen or methyl. , n is 0 to 2, Y is O or S, X is O, NH or S, R ₅ is hydrogen when X is O, or a straight chain of C ₁ to C ₁₂ or branched alkyl, hydroxyalkyl, such as hydroxyethyl, or salts of alkali metal or alkaline earth metal cations and especially ammonium cations, i.e. acids, with ammonia or organic amines such as hydroxyethylamine or trihydroxyethylamine; or R ₅ is hydrogen when X is NH, amino, optionally 1-3

It is. The novel herbicidal compositions can be applied to the soil by standard methods in the form of dusts, spray formulations, granules, or as aqueous preparations in the form of soluble, emulsifiable or dispersible concentrates. Can be applied to plants. Herbicide applications often require vehicles or adjuvants to evenly distribute relatively small amounts of the active ingredient over a large area. In addition to the vehicle, diluents, wetting agents, stabilizers, gelling agents, evaporation enhancers, penetration enhancers or fillers can be used. Suitable vehicles include, for example, talc, kaolin,
Bentonite, silica gel, lime or crushed rock. Other auxiliaries are, for example, surface-active compounds such as soaps (salts of fatty acids), fatty alcohol sulfonates or alkyl sulfonates. Gelatin, casein, albumin, starch or methylcellulose can be used as stabilizers or protective colloids. To prepare the novel herbicidal compositions, the corresponding phospholipids are dissolved in suitable solvents such as toluene, ethyl acetate, xylene, gasoline, methanol or ethanol or mixtures of these solvents. The choice of solvent will depend on the solubility of the herbicide used.
The herbicide or commercially available herbicidal preparation is then dissolved in the phospholipid solution, optionally with heating. Once completely dissolved, the solvent is distilled off under vacuum while heating. The product thus obtained is then optionally treated with suitable inert auxiliaries such as excipients, leavening agents, emulsifiers, wetting agents,
When producing propellants or granules, standard commercial formulations are prepared by adding disintegrants. When producing granules, the granules can optionally be coated with phospholipids. Coating with phospholipids has the advantage of better handling properties (improved odor, reduced aggressiveness of chemical herbicides). The novel herbicidal mixture can also be prepared by dissolving or suspending the herbicide or standard commercial herbicidal preparation, phospholipid and any necessary adjuvants together in a solvent or mixture of solvents by heating;
It can then be produced by distilling off the solvent under vacuum. The mixture obtained in this way is ready for use. In the case of herbicides that are soluble in water or water/alcohol mixtures, the phospholipids or phospholipids can be isolated by first dissolving the herbicide in water or water/alcohol mixtures and then stirring or applying ultrasound. to produce a solution or emulsion. If an emulsifier is required, it can be added before or after this stirring operation. The emulsion or solution thus obtained is freed from the solvent mixture or water in the customary manner, for example by distillation, spray drying, freeze drying. The product obtained can be used as a dry product, optionally after addition of auxiliaries and excipients. The product can also be re-emulsified or re-dissolved in water to which appropriate auxiliaries have been added and used as a liquid product. Example 1 An emulsifiable concentrate of 1 (95 g in 1) containing MCPA (2-methyl-4-chlorophenoxyacetic acid) as active ingredient is prepared as follows. MCPA 95g, Phospholipon 55 200g, Tween 80 8g, Span 80 2g in 100ml ethanol
and 200 ml of ethanol, dissolved with stirring, and diluted with Shellsol A for 1 hour.
Nasu. The efficacy against dicotyledonous weeds of 1 kg of this formulation containing 95 g of MCPA per 1
Equivalent to that of 1Kg of standard commercial product containing 190g. Example 2 1Kg of sprayable powder (12.5%) containing Linuron as its active ingredient
125.0g, ethanol 100ml Phospholipon 55
