  • NON-TOXIC PESTICIDE COMPOSITION AND METHOD FOR COMBATING PESTS BACKGROUND OF THE INVENTION This invention relates to a toxic, toxic, composition that is useful for combating pests, such as insecticide, for killing aphids, jumpers, (from the scarred family) thrips, weevils, etc. and as acaricide, germicide, bactericide and fungicide in general. These insects belong to a large order of insects (eg homoptera), which have mouths that suck, chew, etc. These insects have been a plague for farmers for many years. Aphids, sometimes called aphids, reproduce in huge quantities in a short period of time and destroy many crops.
  • aphids There are many species of aphids, each of which is colloquially identified by its host plant. For example, the aphid of the apple, the aphid of the cotton, the aphid of the rose, etc. Most aphids winter in their specific plants in the egg stage.
  • the jumpers feed on the leaves and are also vectors of organisms that cause plant diseases. These insects suck the sap of the leaves and reduce or destroy the chlorophyll, which leaves the leaves yellow or brown.
  • insects and also the mites are born or sa-iei. from the egg in plants the pesticide can therefore be applied ⁇ . plants that are infested with insects and mites.
  • Do legal regulations set limits on the amount of waste? chemicals that can be left in fruits and vegetables to ensure they are well below danger levels.
  • consumer groups protest that pesticides could result in tens of thousands of cancer cases over the next 50 years.
  • the use of pesticides, fungicides, herbicides, insecticides and plant growth regulators has more than doubled their use during the period 1969-1989 to approximately 820 million pounds annually.
  • This invention relates to non-toxic or phytotoxic pesticides (insecticides, acaricides, fungicides, bactericides and germicides) that provide a solution for the problems associated with insecticides, acaricides, fungicides, toxic agricultural bactericides.
  • the toxic pesticides that are currently used to control insects and mites work by attacking the central nervous system and kill by paralysis or attack the ethanol cycle of the insect or mite and interrupt its development causing death.
  • compositions are dispersible in water and are applied to the cultures in the form of aqueous dispersions.
  • the minor additives in these compositions are simply added for the purpose of facilitating the mixing of the active ingredient with the water.
  • These additives are not effective, in the insecticidal compositions described, for killing insects. Death occurs only by contact with the active ingredient, metomyl.
  • the active substances are also used as powders in vehicles or solid carriers such as kaolin, plaster, limestone, sodium and potassium alumina silicates, corn or other flours, sawdust, cellulose powder, activated carbon and the like. Dust is spread on plants infested with harmful insects.
  • the object of the present invention is to 'provide a non - poisonous pesticide that is totally effective insect killing mites, fungi and bacteria, leaves no poison of any kind in crops, is economical, easy to dissolve and apply without special equipment .
  • the pesticide is not phytotoxic or harmful to the environment.
  • These objects are achieved using a composition that kills insects, mites, fungi and bacteria by physical rather than chemical means.
  • the composition is adhesive or sticky. Catch insects and mites and keep them trapped until they die.
  • the compositions are film-forming and when sprayed on insects and mites, the deposited film blocks the spiracles of the insect's tracheal system and mite and kills by suffocation.
  • the aphids are fixed slightly to the infected plant and some are eliminated by the spray stream. But the adhesive film that covers them cuts off the oxygen supply normally received through the tracheal system.

  • the solution is sprayed into small droplets, which are 50-400 microns in size, that settle on the leaves of the plant and form a film that traps insects and mites and covers their eggs.
  • ether derived from cellulose is soluble in cold water, farmers can prepare the solutions on the farm in drums of 50 to 100 gallons without the expense and hassle of heating the water.
  • Water preferably contains a surfactant to reduce surface tension and facilitate the wetting of insects, mites, fungi and plant leaves.
  • the water-soluble ether derived from cellulose is added as a powder and easily dissolved with stirring.
  • the viscosity of the polymer solution ranges between about 10 and about 3,000 centistocs, preferably 100 and 500 centistocs. Below 10 centimeters the drops do not adhere to insects and other organisms and plants, and drain. No films are formed about insects and other organisms.
  • the surface tension is so great that the film formed is discontinuous so that many of the insects, mites, fungi, etc. they have not just been immersed in the movie. Accordingly, the viscosity of the solution is importantc- for the preparation of solutions of the invention.
  • sodium carboxymethyl cellulose is an anionic cellulose ether available as a powder or granules having a granulometry of 50 to 200 microns.
  • the CMC is commercially available in a DS range of 0.38 to 1.4, with DS being the degree of substitution of the -CHzCOOKa groups in the -OH groups of the beta-anhydroglucose rings comprising the ether polymer of cellulose. There are three hydroxyl groups in each ring so that the maximum value of DS is three.
  • the viscosity of the solutions prepared from the CMC increases.
  • CMC is produced commercially in different viscosities.
  • the viscosity is expressed as the intrinsic viscosity in a 2% solution measured at room temperature.
  • Commercial CMC polymers used to illustrate this invention are designated by their viscosity ranges, for example 10-20, 400-800 and 3000-6000 centipoise. Mixtures of CMC having different intrinsic viscosities may be used for the purposes of the invention as long as the resulting solution has a viscosity within the specified limits. As indicated, this range is between 10 and 3000 centimeters, of kinematic viscosity (1 centipoise equal to 1 centistoque multiplied by the density of the liquid).
  • CMC is commercially available and is produced by several manufacturers. Commercial products used in connection with this invention have been obtained from Sigma Chemical Co. of San Louis, USA, as product nQ C8758 (CMC low viscosity, 10-20 centipoise) and product nQ C4888 (CMC medium viscosity, 4- 800 centipoises). The higher viscosity CMC (3000-6000 centipoise) can be obtained from the Aldrich Chemical Co., Mil Aukee, Wisconsin, USA, with product number 32000306-3).

  • the surfactants help to make the solution droplets spread on the waxy sheets and penetrate the waxy protective coating of insects, mites, and their eggs, as well as coat spores and fungal mycelia.
  • the films of the invention are hygroscopic and collect moisture from the air. In some cases, it is desirable to keep the film in a wet and sticky state for up to 24 hours to catch insects that are not in the plant at the time of spraying. This is done by adding a non-toxic salt such as lithium chloride, lithium acetate or potassium acetate in an amount of 0-1.5% by weight.
  • a solution is prepared by dissolving 5 grams of CMC of low density (10-20 centipoise) and 5 grams of CMC of medium viscosity (400-800 centipoise) in 480 grams of water.
