Belay 50WDG is a product of Valent U.S.A. Corporation.

It can be used in addition to imidacloprid and thiamethoxam. It has the same Mode of Action as imidacloprid and thiamethoxam, hence they all three should be alternated with other chemicals with a different Mode of Action.

Update on Citrus Black Spot By, Dr. Megan Dewdney Citrus black spot (CBS) has continued to be a problem in South West Florida in Collier and Hendry Counties. The number of finds and disease intensity are higher than in 2010. We were finding symptoms that were not present last year such as false melanose and virulent spot. So far most finds have been on Valencia and the symptoms have been visible in mid to lat e March. DPI says that there have been no new suspect finds in the last 2 weeks. The quarantine areas have expanded, but revisions from APHIS are expected as the most recent finds are taken I n to account. In found Guignardia spp. ascospores, the spores responsible for the majority of infections, in all months except December 2010 and January 2011. Spores were first found in mid February and by early March, modera te to large spore numbers were trapped. This means that the fungus is active at the moment but it is unclear what this means in terms of disease control at this time of year. The first year of spore trapping has yet to be completed. Spray a pplication s for black spot should go out no later the beginning of May. See the Florida Pest Management Guide for further control details. NOW is the time to be looking intently in your groves for Citrus Black Spot. You and your workers are in your groves every day! I have posters with pictures of Citrus Black Spot that you can have to post up at your assembly point for workers each day. I can get copies to you. If you would like for someone to come to your shop and present a brief program on Citrus Black Spot, I D just let me know. If Citrus Black Spot is in your grove, the sooner you know it, the better the results will be.

4 Update on Sweet Orange Scab By Dr. Megan Dewdney Sweet orange scab finds are spreading through the state with 11 counties considered positive. Most of the fruit have been from dooryards with only 2 finds in commercial groves, 1 in Sarasota and another in Indian River. The most recent find was in Polk C ounty but not near commercial sites. A f ew suspect finds were submitted to DPI in the last few weeks. lab and DPI continue to be unsuccessful in isolating a fungus but have been able to get a positive PCR test. We are not sure what is actu ally occurring in Florida yet. Despite this, APHIS had placed Florida under a state wide quarantine along with Arizona, Texas, Mississippi and Louisiana. In Texas, there have been fungi isolated from frui t in commercial groves. Dr. Dewdney is working with Texas to determine if their isolates cause disease but this is on going.
