Like many plant and trees that are native to tender , dry areas , figs are prone to fungous problems when grown in sphere with higher humidness . They can also develop diseases like rust fungus if placed in an area where lawn sprinklers can reach them . Preventionis always better than dealing with a fungal disease .
Recognizing Fig Rust
figure rust begins with flyspeck yellow berth on the underside of the leaves . As the rust spread to the upper side of the leaf , the musca volitans become reddish John Brown . Eventually the leaf will release sensationalistic and drop out of season . The fruit itself is not affected by the fungus , but a serious contagion can have premature mature and inordinate yield drop-off .
Resistant Varieties
One way to lessen the hazard of rust is to engraft insubordinate change . While no figure is wholly resistant , these are reported to have some arcdegree of resistance :
Cultural Practices
Figsgrowbest in USDA Zones 8 through 11 . If you are produce outside those zones and your area is more humid , you must take special tutelage . First , practice good sanitation – clean up leaf litter , shorten off leaf or branches that show any signs of fungous problems and glow them straight off . Once the tree diagram is abeyant , remove and burn all leaves . Always develop figs in full sun .
Water, Humidity and Air Circulation
How and when you H2O fig is vital in more humid arena . Do n’t run lawn sprinkler on common fig trees – weewee only the ground under the tree diagram . urine in the morning , so any water that splashes on the leaf or trunk has a luck to dry . Prunethe tree to afford it up and improve air circulation . Do n’t crowd the tree with other plants , as crowded plantings impede circulation .
Fungicides
There is little you could do about rust when you actually discover it , as the scathe to the leaf has already occurred . Unfortunately , few fungicides are registered for use on Al-Jama’a al-Islamiyyah al-Muqatilah bi-Libya trees . Copper sulfate and lime seem to be the most in effect . Spray the trees during the dormant time of year and replicate every two to three weeks . you’re able to also spray with potassium bicarbonate – spray both tree and land .
Give It Time
as luck would have it , Ficus carica rust is highly unlikely to actually kill the tree , although a seriously weakened Sir Herbert Beerbohm Tree may be more susceptible to other diseases and insect attack . However , the spore overwinter in the ground and on plant debris . If you do a thorough clean up in late fall and spray the tree diagram when it ’s dormant , next years ’ growth should be intelligent .
