Be sure to familiarize yourself with the potential or existing pest and diseases issues. Your county Cooperative Extension is an exceptional source for this information. Documents for management and identification, assembled by your state universities, may already exist online. Growers and your local garden centers are also sources of disease and pest control locally.
In places, a consistent and proper spray program can be paramount to your tree's survival. Before they become problematic, potential problems can be avoided with sprays. To get the maximum return on the investment of energy and your time, spraying trees should be performed thoroughly and consistently following the instructions below.
Before starting, read and follow all directions on the labels that you have in hand. Unless the labels on each spray included state which you could do so, don't combine any chemicals.
A home spray tool for trees contains growing-season in addition to dormant-season sprays for diseases and insects. Research your location and find out about disease or any pests which are common locally. Consider planting easy-care , trees, if you understand tree diseases are common in your area.
Note: Contact your local county Cooperative Extension for other suggestions and advice on chemical and cultural control methods if particular sprays provided by Stark Bro's aren't suggested for use in your region.
