Definitions
- the invention relates to a crop protection formulation with a long-lasting, uniform effect.
- Plant protection products are generally applied to the plants in liquid, dissolved or dispersed form by spraying or spraying. There, however, they usually only become effective over a short period of time, as they are quickly removed by wind and rain. They then penetrate into the ground and thus also into the groundwater, which is contaminated as a result. Because of the short duration of action, the spraying must be repeated at short intervals. For this reason, there is an increasing tendency to encapsulate crop protection agents in the form of powder or fine droplets in polymer shells, which is usually done by polymerizing the corresponding monomers in the presence of the finely divided crop protection agents in aqueous dispersion. The agent can slowly diffuse out of this coating and is then effective longer (“slow release”).
- the invention was based on the object of providing an environmentally friendly alternative to this rather complex method of working.
- the invention relates to a crop protection formulation with a long-lasting effect, in which volatile crop protection agents are distributed in a matrix of a crosslinked polycondensate containing hydrophilic groups, with which they form a sponge-like mass from which the crop protection agents are slowly released and evaporate or evaporate . sublimate.
- Plant protection products in the sense of the invention are volatile herbicides, insecticides, repellents, fungicides, nematocides and acaricides.
- Preferred polycondensates are condensation products composed of a maleinized or epoxidized polymer and a crosslinking agent, preferably a polyamine.
- Suitable polymers are e.g. B. reaction products of polydienes, such as polybutadiene, polydecadiene and soybean oil with a molecular weight of more than 400 with maleic anhydride, further copolymers of olefins, such as ethylene with maleic anhydride, and epoxidized polybutadiene.
- Preferred crosslinkers are polyamines, in particular polyoxypropylene diamine and polyoxypropylene triamine. Triethylene glycol, polyethyleneimine and urea are also suitable as crosslinking agents.
- the crosslinking reaction can be carried out in the presence of the liquid crop protection agent and / or in alcoholic solution, e.g. B. in dipropylene glycol at elevated temperature.
- the maleic anhydride or epoxy groups or the -NR-CO groups of the crosslinked polymer and the -CRH-O groups derived from the polyoxyalkylene polyamine have a hydrophilic effect.
- the cross-linked polycondensates are able to handle liquids and gases, e.g. B. to absorb finely divided crop protection agents in liquid, dissolved or dispersed form, an open-cell sponge structure being formed.
- the cross-linked polymer has a spatial network in which the volatile foreign substances can be absorbed and absorbed, so that the polymer swells very voluminously like a sponge.
- the three-dimensional network consists of unit cells which have an average volume of 1 to 1000 nm 3 , preferably 3 to 200 nm 3 .
- the crosslinked polycondensate is loaded with the crop protection agent and forms a sponge-like mass with it.
- the agent is released slowly from it and can then develop its effectiveness.
- the crop protection agents can either be added during the production of the crosslinked polycondensates by condensation, or the crosslinked polycondensate can be soaked with the crop protection agents and thus swell.
- the plant protection product should be contained in the sponge-like mass in amounts of 10 to 90% by weight, preferably 40 to 80% by weight.
- the sponge-like mass can also contain further additives, in particular water in amounts of at least 0.1% by weight, preferably from 1 to 20% by weight and in particular from 1 to 8% by weight Sublimation aids and flame retardants.
- the crop protection agent is coordinated with the crosslinked polycondensate used and, if appropriate, the water in such a way that it is released from the sponge-like mass only very slowly and evenly during the period of action, and its effect is at least three weeks, preferably at least two months and in particular persists for more than three months.
- the sponge-like mass which contains the active agents, can be used in the form of crumbs, chips or granules. However, it is preferably used in the form of plates or strips, preferably with a thickness of 0.2 to 5 cm, in particular of 0.5 to 3 cm.
- the crumbs, chips, or granules can be sprinkled directly on the ground or on the plants.
- Panels or strips can also be placed on the floor, but they are preferably placed in nets or grids, which are then hung on suitable racks or wire structures or placed between two parallel, all-round panels that are set up on posts.
- An essential advantage of the plant protection product formulation according to the invention is that that it is hydrophobic and therefore cannot be washed out by the rain.
- the sponge-like mass obtained was ground into coarse crumbs, which were applied to a corn field and developed their fungicidal action there.
