We have developed a table outlining the recommended insecticides for BMSB and their use restrictions to aide growers in making management decisions. Please note that the table has been revised since its original publication.

Marucci Research in Cranberry: Insecticide Trials Against Blunt-nosed Leafhoppers
Semi-field bioassay testing efficacy of
insecticides on leafhoppers.
Recently we conducted an experiment to test the efficacy of a newly-registered insecticide (Closer SC) in cranberries against blunt-nosed leafhopper nymphs.
Closer (Dow Agrosciences) is an insecticide for the control of sap-feeding insects, including leafhoppers, aphids, and whiteflies. It has both systemic and translaminar activity, belongs to a new class of insecticides (the sulfoximines), and has minimal impact on beneficial organisms.
Insecticide control for leafhoppers is best achieved pre-bloom when targeting the nymphal stage, i.e., immatures. Broad-spectrum insecticides (e.g. Lorsban) are currently recommended for their control. Thus, Closer may provide an alternative to broad-spectrum insecticides and likely be more compatible with biological control because it has less of an impact on natural enemies. [Read more…]

Cranberry: Insect Update 6/28/2013
As we approach the end of bloom, growers should consider the need for any post-bloom applications. The main pest targets for these applications are mainly Sparganothis fruitworm and spotted fireworm. [Read more…]

Brown Rot Found in Nectarines
Last week a block of Fantasia nectarines was found to have a very small percentage of rot present. This week several more blocks were found with rotten fruit present. The common denominator between the three is that they were all mid – late season nectarines that had been just thinned or were being thinned during the severe weather pattern we just experienced. Fruit were injured or the stems knocked loose from either heavy downpours or breaking up clusters. In one orchard many of the rotten fruit were dropping so it is likely the stem had been compromised. Any type of injury in these weather conditions can lead to rot infection.
So what should you do?
- Don’t panic! Fruit should have a high degree of resistance at this point. Only fruit injured in some way should be susceptible to rot;
- Maintain good coverage with a full rate of captan during periods of unstable weather;
- If possible, remove all the rotten fruit from the orchard canopy. Rotten fruit on the ground can be removed by discing where sod middles are not maintained.
