Tree Fungicide & Disease Control in Crete

It depends on the specific disease. Here are common symptoms to look for:

General Warning Signs

Spots on leaves or needles: Brown, yellow, orange, or black spots; may have distinct borders or halos

Premature leaf/needle drop: Leaves or needles turning brown and falling off in spring or summer (not normal fall drop)

Discoloration patterns: Yellowing, browning, or unusual coloring that starts on lower/inner branches and progresses outward

Deformed leaves: Curled, puckered, or distorted leaf development

Thinning canopy: Tree becoming progressively sparser, especially lower branches

Unusual growths: Galls, horn-like structures, or fungal fruiting bodies on bark or leaves

Unfortunately, probably not this year. Here's why:

Fungicide is preventative, not curative: It must be applied BEFORE leaves are infected to work

Damage is permanent on current leaves: Spots, discoloration, and deformities on already-infected leaves cannot be reversed

Late application = wasted money: Applying after disease is visible provides little to no benefit

Better approach: Plan to start preventative program NEXT spring before bud break

You really need all three applications for effective protection. Here's why:

Leaf emergence spans 3-4 weeks: Not all buds open at once; single application misses later-emerging leaves

Fungicide washes off and wears down: Rain and new leaf growth require re-application to maintain protection

Spore release is continuous: Fungal spores are produced and released throughout spring; single application doesn't cover entire period

Gaps in protection = infection: Even a few days without coverage allows disease to infect vulnerable new growth

We don't offer single applications because we've seen they don't work. The 3-application program is the minimum for reliable protection.

No, fungicide is preventative only. However, here's what it CAN do:

What Fungicide CANNOT Do

Cannot reverse damage on already-infected leaves (spots stay, discoloration remains)

Cannot restore dropped leaves or needles

Cannot repair distorted or deformed leaves

Cannot bring back dead branches

What Fungicide CAN Do (If Tree Has Been Infected in Previous Years)

Prevent THIS year's new growth from infection: This spring's new leaves will be protected

Stop disease progression: Tree won't get WORSE; damage is contained to previous years

Allow tree recovery: With healthy new foliage, tree can rebuild strength and vigor

Break disease cycle: Protects tree long enough for environmental fungal spore load to decrease

Depends on tree size and number:

Single medium tree (20-30' tall): 15-30 minutes including setup

Large tree (40-60' tall): 30-60 minutes

Multiple trees: Additional time per tree, but efficiency improves with more trees (setup once)

You do not need to be home during application. We'll notify you day before and leave confirmation after completion.

Yes, when used properly:

During application: Keep people and pets inside or away from treatment area until spray settles and dries (typically 1-2 hours)

After drying: Safe for normal activity around trees; product bonds to leaf surfaces

Beneficial insects: Fungicides target fungal diseases, not insects; minimal impact on bees, butterflies, etc. (unlike insecticides)

Environmental safety: Professional products are formulated for minimal environmental impact when applied correctly

Yes, but with important considerations:

Product selection matters: We use fungicides labeled for fruit trees with appropriate pre-harvest intervals

Ornamental vs. edible: If tree is purely ornamental (crabapple for flowers, not eating fruit), any fungicide is fine. If you eat fruit, we use appropriate products.

Disclosure required: You must tell us if you harvest and consume fruit so we use correct products

Harvest timing: Most fungicides have waiting periods (14-60 days) between last application and safe fruit harvest; this is usually fine since spring applications are finished before fruit matures

Depends on how much is left and tree species. General guidelines:

Good Candidates for Treatment (Likely Success)

Tree retains 50%+ of normal foliage density

Branches still have live buds/growing points

No significant dead branches (beyond disease-related needle/leaf loss)

Tree is otherwise healthy (no other major problems like borers, root issues)

Poor Candidates (Treatment May Not Save Tree)

Tree has lost 70%+ of foliage over multiple years

Large sections of tree completely bare with no signs of new growth

Significant branch dieback beyond just needle/leaf loss

Multiple problems (disease + drought stress + pest damage)

We'll be honest: During assessment, we'll tell you if we think treatment is likely to save the tree or if removal is the better option. We won't take your money for a treatment unlikely to succeed.
