“…AKESSON and YATES (1986) reported the best droplet size to be between 200 µm and 400 µm. GRINSTEIN et al (1997) examined the influence of droplet density and droplet size on the efficiency of two kinds of fungicides against Botrytis cinerea on roses. The active substances were pyrimethanil -300 g/l and tank-mix prochloraz-Zn -150 g + folpet -600 g/l.…”

The effects of droplet spectra, spray volume, and the addition of an adjuvant to the spray solution against Phytophthora infestans were evaluated using contact fungicides, mixtures of contact and systemic fungicides, and a contact fungicide + an adjuvant. Six droplet spectra, ranging from VMD = 183 µm to VMD = 939 µm, were used. The spray volumes were 300, 450 and 600 l/ha for the contact fungicides, and 300 l/ha was used for the mix of contact with systemic fungicides. No significant differences in efficiency were observed between different droplet spectra when used for the mix of contact with systemic fungicide treatments. However, the efficiency of treatments with a contact fungicide significantly increased with smaller droplet spectra. The larger droplet spectra required larger spray volumes for greater efficiency. The addition of the adjuvant (pinolene, 96%) to the spray solution of the contact fungicide caused the efficiency to be similar for all droplet spectra. The effect of droplet spectra is more pronounced in contact compounds. The translocation of the systemic compounds and the ability of the surfactant to improve the coverage with contact compounds may be the main mechanisms that counteract the effects of larger droplet spectra and lower leaf coverage.

“…However, as emphasized by several growers, reaching the underside of the leaves (abaxial; positions 2 and 4), the level of penetration in the crop and the uniformity of the spray distribution are important factors determining the bio‐efficacy of a treatment. This opinion is supported by many authors . Based on this conclusion, special attention is given to the abaxial deposition, penetration and uniformity of the spray deposition in subsequent discussion.…”

“…The best-known chemical classes for B. cinerea control include the chlorobenzenes, benzimidazoles, and dicarboximides (Panagiotarou and Chrisaugi 1998). Grinstein et al (1997) tested pyrimethanil and prochloraz + Zn + folpet against B. cinerea infecting rose flower stems. Prochloraz + Zn + folpet controlled infection by increasing plant cover density.…”

“…In contrast, pyrimethanil + Zn + folpet was better in preventing B. cinerea disease when rose petals were exposed to vapors, and no direct contact with the fungicide was used. It was concluded that Botrytis blight was delayed when cut rose flower bunches were wrapped in packing paper strips or cellophane bags and previously sprayed with pyrimethanil (Grinstein et al 1997).…”

Pre-and postharvest disease control for ornamental plants is mainly provided via fungicide or bactericide application. However, disease control with conventional chemical compounds carries the risk of resistance development by new pathogen races. Additionally, there is increasing public concern over fungicide usage in terms of human and environmental risk. For this reason, and over the past 20 years, researchers developed novel postharvest disease management strategies for cut flowers and other ornamentals. For example, the generally recognized as safe host defense inducers may provide an alternative solution to socially and environmentally less desirable control using conventional fungicides. There are also various biological agents and microorganisms that affect disease
