Dust formulation

Eight isolates of entomopathogenic fungi were evaluated as dried conidia against the rice moth, Corcyra cephalonica. In bioassays two isolates of Beauveria bassiana (BbGc and BbPs) and one isolate of Metarhizium anisopliae (MaPs) consistently gave high mortality to C. cephalonica larvae. Formulations in either kaolin, talc or tapioca flour (20 % w/w a.i.) thoroughly mixed with long grain rice in plastic cups (8 cm diameter by 5 cm) gave complete larval mortality by the 12th day of treatment.

Seventy two weaned Syrian hamsters of either sex were randomly assigned to six treatments in single cages (290mm X 220mm X 140mm) in a closed room where the temperature and relative humidity was maintained 24±50C and 60±15%, respectively during the trial of 56 days. The experiment consisted of four dietary treatments. The concentrate mixture of all the groups was formulated using wheat, fish meal, ground nut cake, mineral mixture and common salt. Additionally, treatment group T2, T4 and T6 were provided with green tea extract. Green tea extract was prepared by inserting green tea bag (1.

‘Seed balls’ are prepared by non-governmental organizations and enthusiastic school children to trees grow trees rapidly for ecosystem restoration. However, there is immense scope for technically improving the seed balls by ensuring the quality of seeds as well as media; further preparing cuboid structures, instead of ball like structure has immense scope in facilitating rooting of the newly emerging seedlings. Against this back drop, a series of experiments were conducted to standardize the seed coating technique, seed priming method and appropriate media for making seed cubes.

Available primarily as an emulsifiable concentrate, these materials are used mainly as space sprays for fly control. About 6 million square feet of the area in North Carolina poultry houses (3 percent) are treated with pyrethrins. The insecticide (synergized with PBO) is generally applied at a rate of 0.0002 to 0.001 pound of active ingredient per 1,000 cubic feet of volume. It is used to treat 6 percent of breeders and layers for mites and lice at a rate of approximately 0.01 pound of active ingredient per 100 birds.

Available as a dust, wettable powder, and emulsifiable concentrate, permethrin is used on more than 10 percent of the birds (layers, breeders, pullets) treated for ectoparasites. Treatment is most often applied to birds at a rate of 1 gallon of spray (0.004 pound of active ingredient) spray per 100 birds. Premise application at the same concentration is made at a rate of 1 to 2 gallons spray per 1,000 square feet of surface area. Dust formulations (0.25 percent) are applied to birds (dust boxes) and premises (litter) at a rate of 1 pound (0.003 pound of active ingredient) per 100...

Available as a dust and wettable powder, Tetrachlorvinphos is applied to about 18 percent of the birds treated for ectoparasites and 10 percent of premise area (20 million square feet) to control various pests. Treatments are generally applied as high-pressure sprays at a rate of 1 gallon of spray (0.04 pound of active ingredient) spray per 100 birds. Premise applications for a variety of pests are made at a rate of 0.05 to 0.8 pound of active ingredient per 1,000 square feet of surface area. Dust formulations are applied to birds (dust boxes) at a rate of 0.01 to 0.2...

Available primarily as an emulsifiable concentrate and dust, malathion is used as a premise treatment on approximately 6 percent (12 million square feet) of poultry house area by North Carolina producers. Premise treatments are applied for fly and beetle control at a rate of 0.08 to 0.2 pound of active ingredient per 1,000 square feet of surface area. Dust formulations are applied at about 0.8 pound of active ingredient per 1,000 square feet. The status of malathion is not yet clear, but many livestock and poultry uses have been voluntarily cancelled.
