Description

Method and device for protecting crop plants

The invention relates to a method for protecting crop plants. The invention further relates to a device for carrying out the method.

Harmful organisms, like insects, acarides or fungi, are a major threat to harvests worldwide and require an extensive use of plant protection agents (pesticides), like insecticides and fungicides

Although the continuous research and development in this field has led to products with considerably reduced toxicity for humans and improved environmental compatibility, there is still the problem that some application methods lead to a certain level of pesticide residues in the plants. This is prohibitive for the use of certain highly effective pesticides. With other pesticides it may delay the possible consumption or processing of fruits and vegetables which could be undesirable with regard to harvesting, storage and sale of the respective products.

Accordingly, there is still a high demand for methods by which crop plants can be protected from harmful organisms that allow the choice of certain effective pesticides with- out causing considerable residues of pesticides in the plants.

It is known, e.g. from WO 2005/060472 that impregnating mosquito nets with certain insecticides can enhance the efficacy of the net and prevent sleepers from insect stings which could transmit diseases like malaria.

However, such nets are mainly used indoors and although they should show wash fastness, i.e. they should retain their insecticidal activity even after several washings, such nets are not continuously exposed to light, rain and wind.

JP-A 08-163 950 discloses a resin net, produced by compounding a polyolefin resin with a pyrethroid insecticide, for controlling insects parts and, inter alia, agricultural and horticultural uses. According to the disclosure of this document, however, the main intended purpose of this net is to be used "indoors", e.g. in greenhouses, stables and residences.

WO 03/003827 discloses a fencing structure comprising a substantially upright structure with a height suitable to prevent low flying insects to enter an open air area. The structure is impregnated with an insecticide. Because of the fencing structure it is not necessary that air, water and light can easily penetrate the structure, as the plants are not completely covered by the structure. As a consequence, the rain fastness of the structure can e.g., be improved by making it highly water repellent.

If, however, the whole plant is to be protected by an impregnated netlike structure, several partly contradicting requirements have to be met. Firstly, it is necessary that air, light and water can freely reach the plant in order to ensure its growth and well being, secondly, harmful organisms have to be prevented from entering the structure, and, thirdly, the impregnation of control agents needs to be weather-fast to a certain extent.

It has now been found that all these requirements can be met by protecting the plants with a tent-like device which has been impregnated with certain pesticide binder combinations.

Accordingly, in one aspect of the invention there is provided a method for protecting crop plants from harmful organisms, comprising the step of covering one or more of the plants with a device, comprising a stabilizing structure and a meshed fabric, where the meshed fabric is impregnated with a pesticide and is penetrable by light, air and water.

According to the invention, crop plants can be protected from harmful organisms in an easy and efficient way without health hazard to workers and without causing residues of pesticides in the plants or products resulting therefrom.

In a further aspect of the invention there is provided the use of the said device for pro- tecting crop plants from harmful organisms.

In yet a further aspect of the invention there is provided a device for protecting crop plants from harmful organisms comprising a stabilizing structure and a meshed fabric, where the meshed fabric is impregnated with a pesticide and is penetrable by light, air and water.

The terms "protection" or "protecting" as used herein means a controlling or repelling action.

The term "harmful organism" as used herein means pests, specifically arthropod pests, including insects and arachnids, and harmful micro-organisms, specifically fungi includ- ing spores, microbes and viruses.

The term "covering" as used herein means that the fabric or netting forms a physical barrier between the plant to be protected and the harmful organism, but does not imply that the plant is in physical contact with the cover material or that the harmful organism is prevented from reaching the plant.

The meshed fabric is made from a non-rigid material. It is preferably a textile material or plastics material selected from the group consisting of yarn, monofilaments, fibers, like staple fibers and continuous bulk fibers (CBF), fabric, knitgoods, especially netting material, nonwovens, foils, tarpaulins and coating compositions. The netting material may be prepared by any method known in the art, for example by weaving, circular knitting or warp knitting, or by sewing parts of a netting to obtain the desired nettings.

The textile material or plastics material may be made form a variety of natural and synthetic fibers, also as textile blends in woven or non-woven form, as knit goods, yarns or fibers. Natural fibers are for example cotton, wool, silk or bast fibers, like jute, linen, ramie, hemp and kenaf.

The device according to the invention comprises a stabilizing structure and a meshed fabric as described above. It can be used to cover one or more plants to be protected for the entire time from seeding or planting to harvest or only for certain stages in the growth of these plants which may be particularly susceptible to attract certain pests.

The fabric is preferably a net, because this does not disturb the exchange of air, humidity and light between the plant and its environment - while it still affords good protection against pests.

Surprisingly, the use of nets leads to a good protection even in the case of fungal diseases.

The invention is further illustrated by the following examples without limiting it thereby.

R⁸ is an organic radical having from 1 to 30 carbon atoms, R⁹ is H or a methyl group, and R¹⁰ is a phenyl group which is optionally substituted or a d- to C₄-alkyl group.

Examples of use

The insecticidal treatment is performed with aqueous dispersions according to example A17 on commercially available white polyester netting material (fiber titer 75 denier, 156 mesh, weight 28-32 g/m²) without prior washing. The aqueous treatment baths are prepared by mixing the aqueous dispersions with commercially available emulsions of insecticide and/or repellent, setting pH with buffer solutions and adding a fixative (if needed). The concentrations of the treatment baths were adjusted according to the liquor uptake possible (LU between 60 and 100 %). The treatment baths are applied by using a padder-stenter equipment on a laboratory scale (Mathis AG, Switzerland). The netting material is fully immersed into the treatment bath and excess liquor is removed by passing it through cylinders which move in counter-direction. By choosing a defined distance between these cylinders (and thus a defined pressure) the liquor uptake can be controlled. The liquor uptake is measured by weighing an impregnated piece of net- ting and subtracting the weight of the dry, untreated netting and is given as % weight of liquor on weight of netting. The drying/curing step is performed in a laboratory stenter which allows to control the temperature and time of the treatment.

For treating insects in laboratory bio-assays insecticidal-impregnated long-lasting in- secticidal nets (LLIN, (S) 200 mg ai/m2) are cut to fit into Petri dishes. Nets are placed on the bottom of the dishes and 10 insects are introduced into each dish on the nets. Mortality/moribundity is evaluated at several minutes, hours and possibly days after exposure. The number of replications is determined on the number of treatments tested. For field trials several methods are available depending on the type of crop. Methods a) to e) are typical examples:

a) Long lasting insecticidal nets as described above are loosely placed directly on plant beds of cabbage and are secured against being removed by wind. The plant can be freely reached by light, air and water. The net is raised by the emergence and growth of the plants, but does not restrict growth.

Infestation by typical pests is recorded until harvesting and compared with the values for plants grown in unprotected beds and plants grown under untreated nets.

b) Long lasting insecticidal nets as described above are placed over poles used for growing tomato plants, in a way that the whole plants are covered by the nets. The tomato plants can be freely reached by light, air and water.

Infestation by typical pests is recorded until harvesting and compared with the values for plants grown without protection and with protection from untreated nets.

c) Long lasting insecticidal nets as described above are placed on a wooden sup- porting frame covering plant beds where strawberry plants are grown. The plants can be freely reached by light, air and water.

d) Tobacco plants in a tobacco nursery are placed under a wire frame covered with a long lasting insecticidal net as described above. The plants can be freely reached by light, air and water.

Infestation by typical pests is recorded and compared with the values for plants grown without protection from untreated nets.

e) Long lasting insecticidal nets as described above are placed over apple trees shortly before blossoming. The trees can be freely reached by light, air and water.
