Definitions

  • Composition for inhibiting gnawing and feeding by insects and animals intended to be applied on seedlings and trees Composition for inhibiting gnawing and feeding by insects and animals intended to be applied on seedlings and trees.
  • the present invention relates to a composition
  • a composition comprising antifeedant (gnawing inhibiting) compounds intended to be applied on seedlings or trees, in order to prevent insect gnawing on the plant, in particular on conifer seedlings and trees, more particularly on pine seedlings and trees to prevent pine weevil, to attack the young stem or the tree, as well as gnawing inhibiting compounds.
  • antifeedant gnawing inhibiting
  • the object of the present invention is to obtain a composition intended to be applied on seedlings and trees in order to prevent damages caused by gnawing on the young plant stem caused by insects, in particular on conuifer seedlings and trees, more particularly to prevent pine weevil (Hylobius abietis) from attacking the young stem or tree.
  • Other gnawing insects are bark beetles. Animals that prefer young tree plants are i.a. deer and moose.
  • a further object is to obtain gnawing inhibiting compounds of such a composition.
  • the pine weevil is the pest insect causing the most serious damages in Swedish forestry. Without any treatment of the newly planted pine and spruce seedlings up to 80% of these young seedlings can become killed by the weevil gnawing for feeding itself on the cortex. An estimated yearly cost of these damages is 0.5 to 2 billion Swedish Crowns only in Sweden depending on the amount and the concentration of weevils.
  • Permethrin prevents the weevil to gnaw the cortex of the seedlings.
  • Permethrin is, however, an environmental poisson having a high toxicity to aquatic organisms. Normally, insects prefer to feed on one or a few plant species. The selection is often controlled by scent and taste substances. The positive ones, i.e. those that tempt gnawing are called stimulants, the negative ones, i.e. those that deter from gnawing are called "antifeedants”.
  • the weevil is polyphag, i.e. it can feed on a number of plants species on a clearing but prefer conifer cortex. If one could direct the weevil away from the conifers, large amounts of or large concentrations of weevil will not play any essential role.
  • the weevil is an insect living on the soil surface where it looks for food. Normally, it does not climb the young seedlings but gnawing takes place within the area, which the weevil reaches on the stem - and around the same - from the soil surface.
  • Another way of inhibiting the gnawing is to treat the plants using a wax. This means a mere mechanical protection.
  • the wax is difficult to apply as it is required that the wax is liquid which leads to increased temperatures which in turn can be a risk to the young seedlings..
  • Neem oil is, however, not equally active against all insects and has turned out to have a limited effect against Hylobius abietis and H. pales.
  • Antifeedant compounds have been proposed in order to prevent or inhibit the feed gnaw by weevils.
  • the desire is hereby that the protection to the conifer seedlings shall last at least two seasons, until the young seedling has obtained a cortex thick enough to stand an attack.
  • the requirements on such antifeedants are that they shall be low volatile, have a high stability at temperatures of up to 70°C and to UN-light as well as have a low toxicity to humans and animals.
  • a model compound which has been tested is carvon, which has turned out to be efficient against the weevil by inhibiting the feed gnaw. It has, however, turned out that the gnawing inhibiting effect is of short duration if the compound is brushed directly onto he seedling. The reason is that carvone is volatile at low temperatures and thus evaporates away from the seedlings treated.
  • PCT/SE01/01458 to solve this problem by means of a composition which is characterized in that the gnawing inhibiting compound is present in a bound form to a substance of the group of zeolites, cyclodextrines, homogenous porous microspheres, spherical vesicles, hollow fibres, such as textile fibres (wool) capillaries of synthetic material (polymers), starch, gelatine, and polymer films, optionally in combination with a carrier and/or adhering agent, whereby the gnawing inhibiting compound in the first hand is present in an amount of 1 to 10 % by weight, and in the second hand is present in an amount of 3 to 5 % by weight.
  • a carrier and/or adhering agent such as textile fibres (wool) capillaries of synthetic material (polymers), starch, gelatine, and polymer films
  • the active antifeedant compounds are selected from three different main groups of organic chemical entities, as follows:
  • R 3 either methyl, ethyl, isopropyl together methylene dioxy.
  • the antifeedant composition comprises a corrosion inhibiting composition of the types containg wax and/or bitumen dissolved in a petroleum base or in a water soluble base, such as the automotive corrosion products sold under the trade mark DI ⁇ ITROL and EFCOAT by EFTEC AB, Sweden.
  • the grains of in particular sperical vesicles of polymer film, gelatine, protein film, where the antifeedant is hidden in a hollow space
  • the gnawing insect is tempted to gnaw on the grains by coating them with an attractant, such as sugar, which sugar coating can be made hard, and can them further withstand a mechanical impact.
  • the coating films used to cover an antifeedant can be made gaspermeable to such an extent that the steam pressure of the antifeedant will pass the gaspermeable barrier to such an extent as to provide an antifeedant, gnawing inhibition, concentration to the insect.
  • the coating film can be made more or less porous, i.e., containing throughgoing pores, and/or the antifeedant can be completed with a steam pressure adjusting additive to increase or decrease of the steam pressure of the antifeedant.
  • antifeedant compound By means of the present invention it is obtained a gnawing inhibition by the sole anti-corrosion composition or optionally in combination with any antifeedant compound as those disclosed abobe in the three groups of compounds previously known.
  • Such further antifeedant compounds may be solved directly in the anti-corrosion composition or may be bound to a substance of the group of zeolites, cyclodextrines, homogenous porous microspheres, spherical vesicles, hollow fibres, such as textile fibres (wool) capillaries of synthetic material (polymers), starch, and polymer films, optionally in combination with a carrier and/or adhering agent, whereby the antifeedant compound is present in the first hand in an amount of 1 to 10 % by weight, preferably 3 to 5 % by weight..
  • the antifeedant compound is physically bound to the polymer or another substance according to the group above, either by a binding in or by inclusion.
  • the antifeedant compound is absorbed in to the zeolite skeleton, at cyclodextrine the antifeedant compound is bound or enclosed at a molecular level, at homogenous porous microspheres the antifeedant compound is present enclosed in a polymer casing (example of such microspheres is Dynospheres T- 12).
  • Dynospheres are compact particles manufactured of 98% of polystyrene, and 2% of divinyl benzene as a cross-linking agent and having a density of 1.05 g/cm 3 .
  • the antifeedant compound is enclosed in a casing.
  • Spherical vesicles can consist of spherical polymer particles , whereby the microspheres consist of a polymer shell which encloses a gas which gas at heating allows the polymer shell to expand more than 40 times and thereby allows enclosure of liquid or solid compound.
  • Phospholipid vesicles can also be suitable as carrier of the antifeedant compound whereby the vesicles being filled with antifeedant compound are slurried in an aqueous phase such as a suspension provided with latex, where the latex has a binding capability to the treated seedling.
  • the amount of antifeedant compound is very high and can be up to 90% by weight, more commonly up to 50 % by weight.
  • the antifeedant compound is normally 1 to 10 % by weight, but can reach 10 to 20 % by weight.
  • Test carried out shows that a micro-encapsulation having a diameter of 200 ⁇ m is eaten by the weevil and can pass the gastro-intestinal tract.
  • the composition is slurried in an aqueous medium and is sprayed onto the seedlings, alternatively the seedlings can be dipped in such a slurry.
  • spraying of the parts of the stem subject to the attack of the weevil in order to minimise the amount of foreign material on the plant, and to minimise the amount of antifeedant compound and binding polymer from a cost and environmental point of view.
  • the antifeedant compound can also be incorporated in a polymer laminate which is wound around the conifer seedling, whereby, when the weevil bites through the outermost film meets the antagonistic compound and is restrained from further gnawing attempts in the area of the first bite. Encapsulation of antifeedant compound can thereby be carried out in a simple way by having a layer of the laminate being provided with the antifeedant compound whereupon a second covering layer is added to the first layer and is adhered or heat sealed thereto. One of the layers can thereby have an adhering layer for the adhesion to a substrate such as the actual conifer seedling.
  • antifeedant compound is meant herein every antifeedant compound that inhibits the feed gnaw of the weevil.
  • AFI in the table above has been determined in accordance with the following.
  • EFCOAT AH 507 Al an oilbased solventfree rust proecting composition comprising i.a. mineral oil 10-25%), 2-diethylaminoethanol ⁇ 2.5%, distilled water 25-30% and having a density of 1 g/cm 3 , a pH of 10.3 and a viscosity of 50 mPas, and is biodegradable.
  • DINITROL 3642W is a solvent-carried rust protecting composition comprising petroleum naphta of two different qualities 25-50%) and 10-25%, repsectively, mineral oil 10-25%) and having a density of 0.85 g/cm 3 , and a viscosity of 220 mPas, and is biodegradable.
