General-purpose spray mixtures for home fruit plantings
"Using the more recently introduced organic insecticides and fungicides, combination sprays have been developed which are reasonably safe on all the major fruit crops of Missouri and which are reasonably effective against most of the important pests of this area. Such general-purpose spray mixtures are especially useful for small mixed fruit plantings where spraying with materials specifically suited to each crop is impractical. Usually, rather than spray each crop with a different combination of materials no spraying at all is done. General-purpose formulations are not ideal and cannot be expected to equal the control obtained in commercial spraying but when correctly applied they usually give an acceptable product for home use. As new pesticides are introduced continued improvements in the combinations of materials are made."--Page 1
