The cool wet spring is delaying bloom and growth in many areas. First fungicides should go out for most folks as soon as the rain pattern breaks. This should be this weekend; looks good for Saturday and Sunday. Most cranberry varieties (except Howes) are approaching 20% bloom at State Bog. Call Sai Sree at ext 18 if you have any questions regarding your fungicide program. Some growers are choosing not to spray chlorothalonil this year, but if you have stocks of the fungicide, you should apply them in 2019 to use up any remaining product.
Now is the time to put out sprays to control scale, if you have an infestation. Please contact the Entomology Lab (x20) if you have any questions. Bees are on most bogs by now. Cranberry fruitworm moths are out flying as are blackheaded fireworm moths. Remember our management for these insects is to target the immature stages (egg or worm stage) not the adult stage. As always, read the label of all products you will be applying to identify any prohibitions or concerns about using the product around bees. Some insecticides like Diazinon, have specific prohibitions.
