Vertical abdominal incisions may be made at the midline, through the linea alba, as well as within about 2.5 cm on either side of the midline (paramedian). If a paramedian incision is chosen, the rectus abdominis muscle can be retracted laterally after incision of the anterior rectus sheath.
Fungicide resistance is the stable, inheritable adjustment by a fungus to a fungicide, resulting in a less than normal sensitivity to that fungicide (Dekker, 1995). In other words, fungicides don't work as well, or at all, on populations of fungi that have become less sensitive to them.
If you have a susceptible tree that you want to protect from rust, organic solutions can be tough. The key words here are prevention and timing. Proper timing of the fungicide applications is vital to prevent rust. Fungicides should be applied from the pink stage until about three weeks after bloom.
