Verbatim
e0“Over 3 years, five crops of winter wheat with different fertilization or pesticide treatments were grown in replicated plots in which straw, cattle manure or nothing was incorporated into the soil”
e4“no differences were demonstrated between treatments in the proportion of phylloplane residents able to produce chitinase, siderophores or antibiotics”

Other claims from this paper (11)
- Intervention effect Straw treatment slightly increased leaf microbial numbers at growth stage 10.
- Intervention effect Straw treatment significantly but slightly decreased leaf microbial numbers at growth stages 60 and 70.
- Intervention effect Leaves of straw-treated plants remained green longer than leaves of untreated plants.
- Association Soil and leaf nitrogen were not linked to microbial populations or soil amendment.
- Observation Microbial numbers were more stable within crops on leaves and ears than in soil.
- Observation Bacteria predominated over fungi in all habitats throughout the growing season.
- Observation More leaf epiphytes than soil microbes produced siderophores.
- Observation Chromogenic organisms were more abundant on aerial surfaces.
- Intervention effect Chlorothalonil reduced the microbial population on wheat.
- Intervention effect Chlorothalonil did not alter the composition of the microbial population.
- Mechanism Straw is postulated to act by altering plant physiology and thereby microbial colonization and disease.
