Malathion 57% can be used on pecan trees at a rate of 1.5 - 2 pints per Acre (24-32 oz per Acre). That breaks down to 0.55 - 0.73 oz per 1,000 square feet. We would recommend using that rate in 1-3 gallons of water in a handheld sprayer. Please see the product label for complete application instructions.
