Abstract/Contents:"Copper preparations, such as Bordeaux mixture, were used almost entirely for treatment of turf diseases prior to the recognition of the value of mercury in their control. Since then the mercury fungicides have largely taken their place. Now that the price of fungicides containing high percentages of mercury has increased so rapidly (See T.T.T., May, 1940), the question of the wisdom of returning it to the use of the copper preparations is frequently raised. Even at the present high prices, the odds are still in favor of mercury. Although Bordeaux mixture is considerably cheaper when compared on the pound-for-pound basis, it should be remembered that in fungicidal activity a single ounce of corrosive sublimate is equivalent for turf use to at least a full pound of Bordeaux mixture and that, therefore, the copper preparation is in reality the more expensive. Moreover, it is easily washed off; it controls only brownpatch whereas the mercury preparations control snowmold and dollarspot as well as brownpatch; and there has been evidence in many cases of injury to the turf due to the toxic copper accumulation which is known to have occurred on some soils. A dependable preventative of such copper accumulation must be produced before the copper preparations can be safely recommended."
