These include stock production. and ornamental plants. Stock and ornamental plants which It has already become known to inject Solutions of may be mentioned are: herbaceous plants, annual and peren certain insecticides or to implant pulverulent formulations nial shrubs and Woody plants, Such as bushes and trees. into the trunks of deciduous and coniferous trees (Chemical The herbaceous plants include vegetables, Such as Abstracts CA 108: 181 188w; CA 99: 83 692v, CA 99: 181 tomatoes, paprika, aubergines, cucumbers, melons, cabbage 184; and CA 87: 146 712). Species, potatoes and tobacco. The perennial shrubs include The method is limited to readily water-soluble active tea and coffee. The woody plants include the known berry compounds having a Systemic action. Handling of the and fruit-bearing Woody plants, pomaceous/stone fruit, method under conditions in practise, that is to Say admin 15 berries, bananas, citrous, grapevines, palms (for example oil istering an adequate amount of active compound into the Sap trees), cacao, olives, hops, roses and rhododendron, and also Stream and thereby damaging the plant only minimally not the Woody plants used in forestry, Such as beech, oak, Spruce only under experimental purposes on a very few plants, is and fir. unsatisfactory.

Such Slow-release shaped articles are insects, arachnids and nematodes, and also fungi and bac used to release active compounds in the Soil over a relatively teria. long time (Chemical Abstract CA 100: 47 099 n; and U.S. The insects include: Pat. No. 3,269,900). Other polymer/active compound for 25 From the order of the Isopoda, for example, Oniscus aSellus, mulations are employed to release readily vapourisable Armadillidium vulgare and Porcellio Scaber. active compounds uniformly into the atmosphere over a From the order of the Diplopoda, for example, Blaniulus relatively long period of time (U.S. Pat. No. 3,318,764). Yet guttulatus. other polymer/active compound formulations are employed From the order of the Chilopoda, for example, Geophilus to protect animals from parasites. For this, the active carpophagus and Scutigera Spec. compound, which migrates to the polymer Surface, is rubbed From the order of the Symphyla, for example, Scutigerella off mechanically by the coat of the animal and distributed immaculata. over the animal (U.S. Pat. No. 3,852,416). From the order of the Thysanura, for example, Lepisma In the customary treatment of plants by atomising, Saccharina. Spraying, dusting and the like, the active compound is 35 From the order of the Collembola, for example, Onychiurus distributed in a suitable formulation as far as possible over (iringiitis. the entire Surface of the plants. It then either encounters From the order of the Orthoptera, for example, Blatta directly the plant pests to be combated, or it has to penetrate Orientalis, Periplaneta americana, Leucophaea maderae, the protective layers of the plants in order to arrive at the Blattella germanica, Acheta domeSticus, Gryllotalpa spp., Sites of action via the Sap Stream of the plant.

The same applies to methods where active From the order of the Dermaptera, for example, Forficula compound formulations are used in the root region, in which auricularia. the active compound is taken up via the roots and arrives at From the order of the Isoptera, for example, Reticulitermes the Site of action via the Sap Stream. Here also, the active 45 Spp. compound must be present in the Soil in a Sufficiently high From the order of the Anoplura, for example, Phylloxera concentration for the plants to be able to absorb enough vaStatrix, Pemphigus spp., Pediculus humanus CorpOris, active compound. Haematopinus spp. and Linognathus spp. To match the amount of active compound to be applied From the order of the Mallophaga, for example, Tri as precisely as possible to the actual requirement of the 50 chodectes spp. and Damalinea spp. plant, it would be desirable for the required amount of active From the order of the Thysanoptera, for example, Hercino compound to be introduced directly into the Sap Stream of thrips femoralis and Thrips tabaci. the plant.
