Definitions
- the invention is directed to the use of defoamers as anti-drift additive.
- the crop protection formulation is admixed with high molecular weight, water-soluble polymers as a tank mix additive, which increase the viscosity of the spray and thus lead to the formation of larger droplets during spraying (see, for example, US 2001/0051145A1, US 2002/0108415 and WO 2008/101818 (US 2010/0152048)).
- a disadvantage of this approach is that, as a rule, an insufficient distribution of the spray on the plants can often be achieved due to the increased viscosity of the crop protection formulation.
- corresponding polymers often dissolve only slowly during the tank mixing process. Insufficiently dissolved polymer residues can here u.a. lead to clogging of the spray nozzles, this then leads to problems such as pressure increase and lack of distribution during the spraying process.
- the present invention is therefore the use of defoamers as anti-drift additives as described in the claims.
- the transversal locomotion of a spray from its point of origin is preferably caused by environmental or / and environmental influences. These environmental or / and environmental influences are preferably wind. This wind can be of natural or artificial origin. Wind of artificial origin is preferential air flows, which arise by the locomotion of a vehicle on land or in the air. These are preferably vehicles or aircraft used in the case of ordering an agricultural area.
- the medium of the spray is in all cases an aqueous medium.
- the spray is formed by atomization in the air.
- Drift is particularly preferably understood to mean the transverse movement of a spray from the point of origin through wind, the spray being produced by atomization of an aqueous medium in the air.
- suitable crop protection formulations of dilute aqueous formulations, so-called spray liquors, which may contain other additives in addition to the crop protection agent are used over a field.
- Atomization in this context means the formation of droplets by mechanical action on a liquid medium preferably by rotation of objects and / or by relaxation (reduction of pressure) at small openings, particularly preferably spray generated by means of nozzles.
- the effectiveness of an anti-drift additive can preferably be quantified by the influence of the additive on the droplet size distribution of the spray. There is a direct relationship between the size of a droplet and its drift tendency - the finer the droplet, the greater the drift hazard.
- droplet size distribution refers to volume-weighted size distributions when measuring the diameter of the droplets in the spray.
- Volume-weighted droplet size distributions can preferably be determined with the aid of laser diffraction measurements (for example by using laser diffraction systems of the Company Sympatec or Malvern according to ASTM method E2798 and therein referred to E1260) or by the computer-aided image analysis of high-resolution, static images of the spray determine. More preferably, the droplet size is determined by image analysis of high resolution images of the spray. Such recordings of the spray are preferably made with the aid of a high-resolution, high-speed camera, whereby a Vision Research Phantom V12 camera is particularly preferred.
- the camera is positioned 12 cm below the nozzle outlet (flat jet nozzle type XR 1 1003 TeeJet) perpendicular to the spray lamella and the spray at a magnification of 1, 15 for min. 20 sec. Recorded.
- the determination of the droplet size is then carried out by image evaluation of min. 2000 independent static images of the spray as described in the examples. From such droplet size determinations, the volumes of the droplets will also be determined.
- the plot of volume percent across the droplet diameter represents a typical particle distribution curve. Such distributions are shown in the figures of this invention. It can thus be used with typical parameters of the distribution, e.g. the volume fraction of the droplets which are smaller than a certain threshold, as well as the maximum distribution and the mean volumetric diameter (MVD).
- the mean volumetric diameter here is a measure used to classify sprays and is defined by the fact that of the atomized total volume of a liquid, 50% of the drops are larger and 50% smaller than this value. Thus, the MVD represents a volume median value.
- the droplet size distribution of a spray depends on the composition of the spray as well as the conditions during the spraying process. For example, the design of the spray nozzle used and the selected injection pressure have a significant influence on the resulting droplet size distribution.
- the spray is preferably produced by the use of nozzles, preferably nozzles of the types flat jet nozzles, long throw jet nozzles, double flat jet nozzles, hollow cone nozzles, full cone nozzles, high pressure nozzles, edge nozzles and air nozzles.
- Injector nozzles more preferred are nozzles of the type of flat fan nozzle. Such nozzles are available, for example, from the manufacturers Lechler, TeeJet and / or Agrotop. Particularly preferred are flat jet nozzles of the company TeeJet, wherein nozzles of the type XR 1 1003 are very particularly preferred.
- a pressure of 0.5 to 10 bar preferably from 0.8 to 8 bar, more preferably from 0.9 to 6 bar, more preferably from 0.95 to 2.5 bar and particularly preferably from 1 to 1, 5 bar applied for spray generation.
- the influence of the anti-drift additives on the droplet size distribution of a spray is always relative to a spray of a formulation which is characterized by the absence of these additives with otherwise constant composition and is sprayed under identical conditions.
- the addition of the anti-drift additives according to the invention preferably causes a decrease in the volume fraction of droplets having a droplet diameter of less than 150 ⁇ m of min. 10%, preferably 15%, particularly preferably 20%, based on the droplet diameter of an identical spray without the addition of the anti-drift additive.
- the addition of anti-drift additives according to the invention causes a relative shift of the maximum of the droplet size distribution of min. 5%, preferably 10%, particularly preferably 15%, based on the droplet size distribution of an identical spray without the addition of the anti-drift additive. Furthermore, the addition of the anti-drift additives according to the invention causes a relative increase in the volume-related median droplet size distribution of min. 5%, preferably 10%, particularly preferably 15%, based on the droplet size distribution of an identical spray without the addition of the anti-drift additive.
- volume median of the droplet size distribution is at least 5% greater than that of a VE water-based spray, wherein the spray with a fan nozzle of type XR 1 1003 TeeJet at a Pressure of 1 bar and a temperature of 25 ° C is generated and the volume-related median is determined by image analysis of high-resolution images of the spray.
- An advantage of the use according to the invention of defoamers as anti-drift additives is that, in addition to their defoaming action in spray mixtures during the spraying process, they reduce droplets which are small and thus driftable, these are preferably droplets with a diameter of less than or equal to 150 ⁇ m , and lead to a reduced "off-wear" deposition.
- the addition of the anti-drift additives according to the invention during the spraying of active substances advantageously brings about a reduction in the contamination of the environment.
- Another advantage is the avoidance of losses of expensive active ingredients, since they are reduced to a higher percentage on the target area, e.g., using the anti-drift agents of the present invention. in the case of agricultural use on agricultural land.
- the defoamer can be incorporated into the spray mixture either in the form of a surfactant-stabilized aqueous emulsion of a suitable defoamer active ingredient or in the form of a self-emulsifying defoamer active ingredient composition.
- a further advantage of the use according to the invention of defoamers as anti-drift additives is thus that the defoamers, due to their dosage form, can easily be incorporated into spray mixtures with gentle stirring. This facilitates on the one hand the preparation of spray liquors. Furthermore, due to the good incorporability and the associated homogeneous distribution during the spraying process, there is no clogging of the spray nozzles.
- the antifoam in the form of a premix consisting of a self-emulsifying defoamer and another Adujvant of the spray mixture can be added.
- Such blends have the advantage of combining the positive anti-drift properties of the defoamer with the efficacy enhancement of the adjuvant.
- antifoams can be incorporated directly into the spray mixture during the tank-mixing process. This leads spontaneously to a sufficiently homogeneous distribution in the formulation.
- the indication of a mass ratio of e.g. Component (a) to component (b) of 0.1 means that a mixture containing these two components comprises 10% by weight of component (a) based on the sum of the sum of components (a) and (b).
- adjuvant describes substances or adjuvants that enhance the action of a plant protection product.
