Description

"Composition, Herbicidal Agent, and Uses of the Herbicidal Agent, and Composition" Description The present invention relates to a novel composition for enhancing herbicide efficacy, the use of this composition to improve herbicidal efficacy, a herbicidal agent comprising this composition and at least one herbicide, and the use of this herbicidal agent to control undesirable plant growth. It is generally known that the absorption and also the effectiveness of many pesticides, such as, for example, herbicides, can be improved by the addition of adjuvants, the so-called reinforcers. The mechanism of action of these additives is complex and cannot simply be attributed to adapted surface properties of the leaf surface. WO 00/53014 describes an improved efficacy herbicidal composition which, in addition to a topramezone-type herbicide, comprises an adjuvant as an action enhancer. It comprises a C5 -C22 alkyl C1 -C5 alkanoate, a C10 -C20 carboxylic acid, a partial phosphoric or sulfuric acid ester of a monohydroxy polyalkyl ether and optionally a polyoxyalkylene alkyl polyether. Preferred C1-C5 alkyl C5 -C5 alkanoates are methyl oleate, methyl palmitate and ethyl oleate, and mixtures thereof. Specifically, the C1-C5 alkyl C5-C22 alkanoate used is a 1: 1 mixture of methyl oleate and methyl palmitate.

Such action enhancer systems are commercially available under the trademark DASH®, for example DASH® HC, from BASF Corporation, USA.

A disadvantage of this action enhancing system is that at relatively low temperatures, sometimes even at 10 ° C, and / or upon prolonged storage, it precipitates and becomes solid. Since the action of the action enhancer system is generally mixed in the spray tank with the herbicide, precipitation prevents dispersion of the action enhancer in the tank mix and the product is no longer applied to plants at a uniform concentration. . In order to ensure good dispersion, the action enhancer first needs to be heated so that it is dissolved, which naturally makes its handling extremely difficult.

It has therefore been an object of the present invention to provide an action enhancing system which does not precipitate at low temperatures, for example below 10 ° C but in particular also at 0 ° C or below 0 ° C at -5 ° C. ° C or below or prolonged storage and thus easier to handle.

The inventors of the present application have found that precipitate formation is attributed to the alkyl alkanoate constituent, and that this can be avoided if the alkyl alkanoate has a certain composition. The object is therefore achieved by a composition comprising: (a) at least one C1-4 alkyl ester of at least one C14-C22 carboxylic acid, wherein the at least one carboxylic acid consists of at least 70% by weight aliphatic carboxylic acids having 18 carbon atoms; (b) at least one anionic surfactant, which is selected from esterified products of monohydroxy-functional alkyl polyethers with inorganic polyproteic acids; (c) at least one aliphatic C14-C22 carboxylic acid; (d) optionally at least one foam suppressor; and (e) at least one aromatic solvent.

Solid vehicles are mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, plaster, limestone loam, rust slime, clay, dolomite, diatomaceous earth, calcium sulfate and magnesium sulfate, oxide. magnesium, milled plastics, fertilizers such as ammonium sulphate, phosphate, ammonium nitrate, urea and vegetable products such as cornmeal, tree bark, sawdust and nutshell flour, cellulosic powder or other solid carriers.

The concentrations of herbicidal agents in ready-to-use preparations may be varied within broad ranges. Generally, the formulations comprise from about 0.001 to 98% by weight, preferably from 0.01 to 95% by weight of the herbicidal agent.

It may be of use to apply the herbicidal agent alone or in combination with other crop protection compositions, for example with pest or fungal or bacterial control compositions, or with regulatory active ingredient groups. of growth. Also of interest is the miscibility with mineral salt solutions which are used to overcome nutritional deficiencies and trace element deficiencies. Other additives such as non-phytotoxic oils and oil concentrates may also be added. The invention further provides the use of the herbicidal agent according to the invention for the control of undesirable plants. In addition, the invention relates to a method for controlling undesirable plant growth in which component A and component B of the herbicidal agent according to the invention are applied together or separately at the same time or in succession to the undesirable plant or its habitat. The order in which components A and B are applied is of minor importance. It is merely essential that composition A and at least one herbicide B are present at the site of action at the same time, that is, at the same time having contact with or being absorbed by the plant to be controlled. The booster composition according to the invention remains liquid at significantly lower temperatures than analogous booster compositions of the prior art. It can thus be handled smoothly even at low outside temperatures and does not need to be heated before use. Its reinforcing enhancing action on the herbicides used together with it is identical or even better compared to prior art products.

Results are presented in the Table below.

In order to show that precipitate formation is effectively attributable to the alkyl ester composition, Edenor® Me Ti 05 and Stepan® C-65 products were stored at low temperatures and investigated for solid constituent formation. At the beginning of the experiments, both products were clear. The results are listed in the Table below: The solid formed at -15 ° C and -10 ° C in the Edenor® ME ti 05 product was redissolved within 6 days at 0 ° C. In the case of Stepan® C-65, this did not occur in any case.
