Timing is important as early spraying may reduce crop yield and late spraying may reduce effectiveness.
Plants must be actively growing so that sufficient material can be translocated from foliage to tuber, but applying too early will reduce crop.
Spray one week after blossom fall or two weeks after full bloom. In conditions when good flowering does not occur spray immediately upon the first sign of yellowing of the tops usually 4-6 weeks before harvest.
Spray in the morning, after most of the dew has dried, towards the evening or spray on cool cloudy days.
Uniform and complete coverage is nec- essary.
Apply when temperature is below 30C.
Best results are obtained when the relative humidity is greater than 85% and no rain or irrigation occurs for a week.
Do not spray if rain is expected within 24 hours or irrigate within 24 hours of application (96 hours in Tasmania)
Avoid spraying crops affected by diseases or pests
Do not treat potatoes which are grown for seed
How to Use - Onions
Green crops are essential for absorption of the product and translocation to the bulb.
Avoid use on crops severely diseased.
Avoid spraying onions too early.
Apply the spray when 50% of the tops have fallen, but while all the tops are still green.
When plants have three green leaves or less and all the tops are down it is usually too late for effective control.
Uniform and complete coverage is necessary.
The use of this product should be combined with selection of a good storing variety.
