Fungicide for control of Powdery mildew and Botrytis on Roses. (RESTRICTED FOR USE IN GREENHOUSES ON NON-EDIBLE CROPS)
Polyoxin AL (Complex 50% w/w)
GENERAL INFORMATION
Polar 50 is a systemic antibiotic fungicide for control of powdery mildew and prevents damage by botrytis in flowers during post-harvest, in storage and transportation.
Timing of application
Start spraying Polar 50 when the first signs of disease infestation are seen and continue at weekly interval until signs of the disease disappear.
For best results, add Bio-Film to the spray mixture in order to aid the activity of the fungicide.
Preparation of spray mixture
Fill the spray tank with half amount of water. Add the required amount of Polar 50 and Biofilm and mix or agitate thoroughly. Add the remaining amount of water and mix or agitate to uniformity.
Application technique
It is important to ensure that good coverage of the target crop foliage is achieved. Always apply Polar 50 until the spray runs off.
A spray volume of 800 — 1000 L per Ha is recommended for flowers.
As a post-harvest treatment for roses, it is recommended that Polar 50 should be applied on the flowers after sorting and grading, and prior to cold storage. Flowers should be sprayed thoroughly to ensure spray coverage on the foliage and flower buds. Care should be exercised to ensure that wet flowers are not put in the cold store.
Compatibility
Polar 50 is compatible with most crop protection agents. However, it is recommended that the user should conduct compatibility and crop safety tests before applying in spray mixture with other products.
Disease resistance
Continued use of Polar 50 alone for an extended period could lead to development of resistant fungal strains. To avoid development of resistance, alternate Polar 50 after 2-3 consecutive sprays with other fungicides with a different mode of action.
Waiting period
Sprayed green house or crop field can be re-entered after the spray has dried.
