Permit for Captan in Almonds
Crop Care Australasia’s Captan WG fungicide can now be used in almonds for controlling Anthracnose, under AVPMA Permit 5654. Crop Care’s versatile protectant is already registered for use in many horticultural crops, including apples, pears, grape vines, strawberries, stone fruit and ornamentals, for a wide range of diseases.
“Trials in Australia and the US have shown that Captan works very effectively against Anthracnose in almonds,” said Kerrie Mackay, Horticulture Product Manager. “It is also registered in the US for blossom blight, brown rot and shot-hole control in almonds and is the number one selling fungicide for this crop.”
Captan contains 800 g/kg captan in a user friendly, high quality granular formulation. A Group Y fungicide, it has very low potential for resistance development, offering multi-site activity.
“Captan should be applied at full bloom petal fall and at two to three weeks and four to six weeks post petal fall. The shorter intervals should be used where there is heavy disease pressure,” said Ms Mackay.
“It should be applied at 200g/100L in 1500-2000L/ha for dilute spraying and up to 400g/100L for concentrated spraying. Concentrations should never be more than twice that of the dilute spraying recommendations for almonds.
“The tank should be agitated as the granules are added and during spraying.
“While additional sprays may be required if the season’s weather conditions are conducive to disease, Captan should be sprayed in a protective program with other fungicides and not more than five times in a season.”
Captan WG may be applied alone or in mixtures, 14 days after oil sprays, Ms Mackay said. “It is compatible with many commonly used pesticides and with most WG, SC and SL formulations including Anvil, Fortress, Hymal, Lannate, Saboteur and Talstar 80 SC.
“But it should not be mixed with Bordeaux mixture, lime sulphur, spray lime, oils and Kelthane. And Crop Care does not recommend use with most ECs including Maldison EC.” Captan is a useful addition to an IPM program, with minimal impact on beneficial insects and mites, said Ms Mackay.
“For example, it has a Category 4 DPI listing for bees which means it can be sprayed at any time. On predatory mites, Captan has been shown to have less impact than Mancozeb.” Captan has a short withholding period of 30 days, allowing its use close to harvest. It is available in 10 kg disposable packages.
