Some Aspects of the Biology and the Control of Southern Cone Rust
Abstract:Southern cone rust, caused by Cronartium strobilinum, accounts for annual losses of about 20 percent of the first year cone crop of slash pine in Florida, Georgia, and the Gulf states. The female strobili are susceptible to infection from the time of emergence from the bud scales through the pollination stage. Hydraulic spray applications of ferbam to the developing pine strobili will control cone rust in slash pine seed orchards when applied at five-day intervals and has no adverse effects on pollen germination, seed-set, or seed germination. Further data on economic considerations must be accumulated before aerial spraying can be recommended.
