Bird Control in Sunflowers
Controlling birds in Sunflowers with Bird Shield™ repellent has been extremely effective. In fields treated with two, one pint applications of the repellent at seven day intervals damage was reduced to about 3% while the untreated fields sustained damage from 78% to 90%. These figures represent samples of individually harvested heads from which the damage was both measured and the total amount of seed produced weighed. Harvest weights ranged from 133 to 700 lbs./ac. (mean = 344) in the untreated plots while weights ranged from 1430 to 1909 lbs./ac. in the treated plots. No adverse effects were noted with fish or resident populations of ducks when the cattail marshes and waterways were over flown during the application process. For a detailed report see our article on the Efficacy of the aerial application of methyl anthranilate in reducing bird damage to sweet corn, sunflowers and cherries.
