Fruit trees, such as apple trees, are susceptible to pests including aphids, scale insects and spider mites. Left untreated a pest infestation can cause serious problems for the fruit of the apple tree. After all, everyone knows about the old adage that you should not eat an apple with a worm inside. For green gardeners or those concerned about the effects of insecticides and pesticides, winter wash may be the right alternative.
Types of Pests
The Gardenseeker website warns gardeners that a variety of pests threaten apple trees. Some common apple tree pests include aphids, scale insects, codling moth larvae, fruit slugworms and spider mites. The biggest threat, according to Gardenseeker, comes if the infestation is left untreated. Adult bugs may burrow their way into the tree and fruit and lay eggs. At this point, the tree becomes infested with larvae, which are more difficult to treat than their adult counterparts.
Winter wash is a pest treatment product that gardeners use on fruit trees, including apple, plum, pear, cherry and peach. It can also be used on a variety of fruit bushes such as blackberry, raspberry and gooseberry, according to the Blackmoor website.
Perhaps one of the best reasons to use a winter wash product is its eco-friendly nature. Winter wash is made from natural products and works through a physical reaction with the pests, according to the Gardencentre website. Winter wash is not an insecticide and therefore does not carry the same ecological threat associated with those methods of pest treatment.
According to Blackmoor, winter wash is an effective way to treat insects commonly found on fruit trees. The product is specifically recommended for treating aphids, including greenfly and blackfly varieties.
The Gardencentre website recommends diluting liquid winter wash products with water according to the directions on the package. Use the diluted mixture in a coarse sprayer and spray apple trees to help repel insect pests.
