| Reasons for need: |
THE FUNGUS RAFFAELEA LAURICOLA CAUSAL AGENT OF THE LAUREL WILT DISEASE ON AVOCADOS; PROPICONAZOLE INJECTED IS GIVING SOME CONTROL BUT SINCE THE FORMULATION IS AN EMULSION THE MOVEMENT IN THE AVOCADO TREE IS LIMITED AND COMPARTMENTALIZED AND IN MANY INSTANCES IT DOES NOT WORK. SILVER IS WATER SOLUBLE OR DISPERSED; THE PARTICLE SIZE IS VERY SMALL AND PENETRATION AND DISTRIBUTION IS VERY GOOD; IN ADDITION, NOT ONLY HAS FUNGICIDAL PROPERTIES BUT ALSO AFFECTS TYLOSE FORMATION THAT CLOGS THE VASCULAR SYSTEM. SILVER INHIBITS ETHYLENE ACTIVITY AN ETHYLENE TRIGGERS TYLOSE FORMATION
