Due to the effectiveness of diflubenzuron

The control of fly larval infestation is important in agricultural in order to avoid the illnesses and economic losses associated with such insect pest infestation. A method of controlling fly larval by direct application to the larval breeding medium is widely known in the industry. The method involves such direct utilization of the compound, N[[4-chlorophenyl)amino]carbonyl]-2,6-difluorobenzamide, sold under the tradename of DIMILIN® insecticide, a registered trademark of Duphar BV of Amsterdam, Holland (hereinafter referred to as diflubenzuron , the generally recognized generic chemical name).

Due to the effectiveness of diflubenzuron when used against fly larvae, the search for a more beneficial manner to control such fly larvae has spurred and continues to spur new research efforts. One attractive method for fly larvae control is to utilize diflubenzuron in feeds for controlling fly larvae in excreted feces. This method is commonly referred to as feed-through application. For instance diflubenzuron at levels of 0.5 to 1.0 mg/kg animal body weight, has been mixed directly into the feed of calves and dairy cattle and has shown effective control of house fly and face fly larval in the feces (R. W. Baker et al, J. Georgia Entomol. Soc., 11 (1976) 1: 67-71 and R. W. Miller, J. Economic Entomol. 67 (1974) 5: 697).

In addition to this direct feed addition method, diflubenzuron  has been encapsulated and tested for insecticidal activity, F. W. Knapp et al., Symp. Int. Meeting Controlled Release Soc. (Academic Press, 1980), as well as being applied in mineral blocks and delivered in a sustained-release bolus form (U.S. Pat. No. 4,166,107, issued to J. A. Miller et al on AUg. 28, 1979).

Procuring and cultivating a garden can be an excellent source of pride and provide a relaxing and rewarding hobby. However, pests such as the velvet bean caterpillar can ruin all the hard work by damaging the garden beyond repair. To control velvet bean caterpillars in the garden, all you need is the ability to follow a few steps and the patience to keep the control measures in place.

The present invention relates to novel compacted granular feed premix compositions containing diflubenzuron. These granular feed premix compositions provide enhanced larvicidal effectiveness and fly control of surprisingly low doses of diflubenzuron manufacturer .

It is an object of the present invention therefore to provide novel such compacted granular feed premix compositions with improved larvicidal effectivness and fly control.

It also is an object of the present invention to provide a method for preparing the novel compacted granular feed premix compositions of the invention.

These and further objects of the present invention will become more apparent by the more detailed description of the invention provided herein.

Place pheromone traps in the garden to capture the velvet bean caterpillar in its moth stage and control the population in your garden. See the Resources section for more information.
Check for the eggs of the velvet bean caterpillar on the underside of leaves and remove the eggs or the infected leaves. This is a difficult means of control because the eggs hatch usually within three days. Therefore, if you choose this measure of control, you need to check and clear the leaves every other day to properly control the velvet bean caterpillar.

The present invention relates to compacted granular feed premix compositions comprising, on a weight basis, about 0.5% to 84.0% diflubenzuron ; about 0% to 10% whole dried whey; about 0% to 2% water and the remainder of a compactable, insoluble carrier to total the composition of 100%.

Compactable, insoluble carriers suitable for use in the compositions of the present invention include clays and mineral salts, such as CaSO 4 , BaSO 4 or other mineral salts, CaCl 2 . The preferred carrier, however, is CaSO 4 dihydrate. Preferred compacted granular premix compositions of this invention have a granular particle size of 10 mesh to 100 mesh, with a particle size range of 20 mesh to 60 mesh being preferred.

This invention also relates to methods for the preparation of these compacted granular compositions. It unexpectedly has been discovered that compositions of the present invention, prepared by the compaction and granulation process of the invention, provide compositions which provide effective control of larvae when administering doses in animal feeds of diflubenzuron at rates as low as 0.025 mg/kg of animal body weight. Surprisingly, the compacted granulated compositions of the invention are more efficacious than diflubenzuron alone, the uncompacted composition or an alfalfa feed premix of diflubenzuron administered in animal feed for the feed through control of fly larvae and resulting fly control (see Table I). This invention also provides an improved method for controlling fly larvae and flies in the feces of animals. This is accomplished by orally administering, in an animal feedstuff or feed supplement, sufficient quantities of the present compositions to provide about 0.025 mg/kg to 10 mg/kg per animal per day of diflubenzurons .

Spray the garden with a chemical treatment of diflubenzuron. This chemical is for retail sale under the name Dimilin. This is a restricted use pesticide and for use with certified applicators only. See the resources section for more information.
Cultivate the ground underneath the plants regularly and check for the pupae of the velvet bean caterpillar. In the larval stage, the pupae caterpillar is brown and milky white in color.
