- the coating can be applied to almost any crop seed that is described herein, including cereals, vegetables, ornamentals and fruits
- the seed may be treated with one or more of the following ingredients other pesticides including fungicides and herbicides, herbicidal safeners, fertilizers and/or biocontrol agents These ingredients may be added as a separate layer or alternatively may be added in the pesticidal coating layer
- the pesticide formulation may be applied to the seeds using conventional coating techniques and machines, such as fluidized bed techniques, the roller mill method, rotostatic seed treaters, and drum coaters Other methods, such as spouted beds may also be useful
- the seeds may be presized 5 before coating After coating, the seeds are typically dried and then transferred to a sizing machine for sizing Such procedures are known in the art
- the pesticide-treated seeds may also be enveloped with a film overcoating to protect the pesticide coating
- a film overcoating to protect the pesticide coating
- Such overcoatings are known in the art and may be applied using conventional fluidized bed and drum film coating techniques
- a pesticide in another embodiment, can be introduced onto or into a seed by use of solid matrix priming
- a quantity of the pesticide can be mixed with a solid matrix material and then the seed can be placed into contact with the solid matrix material for a period to allow the pesticide to be introduced to the seed
- the seed can then optionally be separated from the solid matrix material and stored or used, or the mixture of solid matrix material plus seed can be stored or planted directly
- Solid matrix materials which are useful in the present invention include polyacrylamide, starch, clay, silica, alumina, soil, sand, polyurea, poly aery late, or any other material capable of absorbing or adsorbing the pesticide for a time and releasing that pesticide into or onto the seed It is useful to make sure that the pesticide and the solid matrix material are compatible with each other
- the solid matrix material should be chosen so that it can release the pesticide at a reasonable rate, for example over a period of minutes, hours, or days
- the present invention further embodies inhibition as another method of treating seed with the pesticide
- plant seed can be combined for a period of time with a solution comprising from about 1 % by weight to about 75% by weight of the pesticide in a solvent such as water
- concentration of the solution is from about 5% by weight to about 50% by weight, more preferably from about 10% by weight to about 25% by weight
- the seed takes up (imbibes) a portion of the pesticide
- the mixture of plant seed and solution can be agitated, for example by shaking, rolling, tumbling, or other means
- the seed can be separated from the solution and optionally dried, for example by patting or air drying
- a powdered pesticide can be mixed directly with seed.
- a sticking agent can be used to adhere the powder to the seed surface.
- a quantity of seed can be mixed with a sticking agent and optionally agitated to encourage uniform coating of the seed with the sticking agent.
- the seed coated with the sticking agent can then be mixed with the powdered pesticide.
- the mixture can be agitated, for example by tumbling, to encourage contact of the sticking agent with the powdered pesticide, thereby causing the powdered pesticide to stick to the seed.
- the present invention also provides a seed that has been treated by the method described above.
- the treated seeds of the present invention can be used for the propagation of plants in the same manner as conventional treated seed.
- the treated seeds can be stored, handled, sowed and tilled in the same manner as any other pesticide treated seed. Appropriate safety measures should be taken to limit contact of the treated seed with humans, food or feed materials, water and birds and wild or domestic animals.
- X the kill rate, expressed in % of the untreated control, when employing active compound A at an application rate of m ppm or m g/ha,
- Y the kill rate, expressed in % of the untreated control, when employing active compound B at an application rate of n ppm or n g/ha,
- the kill rates of the combination are super additive, i.e. a synergistic effect is present.
- the kill rate that is actually observed has to be higher than the value, calculated using the formula above, for the expected kill rate (E).
- Emulsifier 2 To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and emulsifier, and the concentrate is diluted with emulsifier-containing water to the desired concentration.
- Cotton leaves ⁇ Gossypium hirsutum) which are heavily infested by the cotton aphid ⁇ Aphis gossypii) are treated by being sprayed with the preparation of the active compound at the desired concentration.
- the mortality in % is determined. 100 % means that all the aphids have been killed; 0 % means that none of the aphids have been killed.
- active compound 1 part by weight of active compound is mixed with the stated amount of solvent and emulsifier, and the concentrate is diluted with emulsifier-containing water to the desired concentration
- Cabbage leaves (Brassica oleracea) which are heavily infested by the green peach aphid ⁇ Myzus persicae) are treated by being sprayed with the preparation of the active compound at the desired concentration
- the mortality in % is determined 100 % means that all the aphids have been killed, 0 % means that none of the aphids have been killed
- active compound 1 part by weight of active compound is mixed with the stated amount of solvent and emulsifier, and the concentiate is diluted with emulsifier-containing water to the desired concentration
- Cabbage leaves (Brassica olerace ⁇ ) are treated by being sprayed with the preparation of the active compound at the desired concentration and are infested with larvae of the beet army worm (Spodoptera exigua) as long as the leaves are still moist
- the mortality in % is determined 100 % means that all the caterpillars have been killed, 0 % means that none of the caterpillars have been killed
- Emulsif ⁇ er 2 parts by weight of alkylaryl polyglycolether
- active compound 1 part by weight of active compound is mixed with the stated amount of solvent and emulsif ⁇ er, and the concentrate is diluted with emulsifier-containing water to the desired concentration.
- Cabbage leaves (Brassica olerace ⁇ ) are treated by being sprayed with the preparation of the active compound at the desired concentration and are infested with larvae of the fall army worm ⁇ Spodoptera frugiperda) as long as the leaves are still moist.
- the mortality in % is determined. 100 % means that all the caterpillars have been killed; 0 % means that none of the caterpillars have been killed.
