Crete Tree Disease Prevention Services

Crete, located just 25 miles southwest of Lincoln, is a close-knit community known for Doane University and its charming small-town atmosphere. Yard Boss brings professional tree fungicide and disease control to Crete homeowners. Trees face many of the same fungal disease challenges as lawns, with common problems including cedar-apple rust on crabapples, needle cast causing browning and needle drop on spruce and pine trees, apple scab, anthracnose on hardwoods, and various rust diseases. Our preventative foliar spray program protects valuable landscape trees during spring when new leaves and needles emerge and are most susceptible to infection. Professional treatment prevents disease before it damages your trees. Common diseases we treat:

Investment in Tree Health and Value

Crete’s mature landscape trees represent significant property investments. A single mature tree can add one thousand to seven thousand dollars or more to property value. Untreated fungal diseases cause progressive damage including premature leaf drop, thinning canopies, and weakening that makes trees vulnerable to insects, drought, and other stresses. For evergreens with needle cast, damage is permanent because needles don’t regrow—lost needles mean bare branches forever. Our preventative treatment stops disease before damage occurs, protecting your tree investment and maintaining property beauty. Custom pricing is based on tree size, species, and the number of trees treated. Multiple trees on the same property receive volume discounts. This service pairs perfectly with deep root fertilization for complete tree health.

Three-Application Spring Program

Our disease prevention program uses three carefully timed foliar spray applications during spring bud and leaf development. The first application occurs two weeks before bud break to establish protection and kill overwintering fungal spores. The second application happens at bud break when buds open and first leaves emerge—the most vulnerable stage. The third application comes two weeks after bud break to reinforce protection as leaves expand and mature. This three-application strategy is essential because leaf emergence spans three to four weeks, fungicide washes off from rain, and fungal spores are released continuously throughout spring. Single applications leave gaps in protection that allow disease to infect unprotected new growth.

how Tree fungal disease work

stage 1

GreenCheckmark

Fungal Spores Present in Environment

Most disease-causing fungi overwinter in fallen leaves, bark, or alternate host plants

stage 2

GreenCheckmark

Spring Conditions Trigger Spore Release

Warm temperatures + moisture (rain, dew, humidity) cause spores to become active

stage 3

GreenCheckmark

Spores Land on Emerging Leaves/Needles

Wind and rain splash distribute spores to newly developing foliage

stage 4

GreenCheckmark

Infection Occurs

In presence of moisture, spores germinate and penetrate leaf tissue, establishing infection

stage 5

GreenCheckmark

Disease Develops

Fungus grows inside leaf, causing spots, discoloration, distortion, or death of leaf tissue

stage 6

GreenCheckmark

Spore Production

Infected leaves produce millions more spores, spreading disease to other leaves and trees

stage 7

GreenCheckmark

Tree Stress and Damage

Severe infections cause premature defoliation, weakening tree and reducing photosynthesis

Professional Equipment and Application

DSC00875

We use professional high-pressure spray equipment that reaches thirty to sixty feet into tree canopies, providing complete coverage that consumer hand-pump sprayers cannot achieve. Our fine mist application coats all leaves, needles, and twigs with professional-grade fungicides that create a protective barrier preventing fungal spore germination and infection. Weather conditions are critical for proper application—we will not spray if wind gusts exceed ten miles per hour because wind causes drift, uneven coverage, and reduced effectiveness. Crete clients receive notification via text or email the day before scheduled service. If conditions are unsuitable, we reschedule for the next calm day to ensure proper application.

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.
