EPA Registers IBA... 



Reprinted from November 12 

 AAN Update. 



The US Environmental Protection 

 Agency issued conditional registra- 

 tion on technical grade Indole-3-Bu- 

 t\aic Acid in late October. "Condi- 

 tionar means some data are still be- 

 ing prepared, but no major complica- 

 tions are foreseen. Plant propagators 

 should not see any IBA product 

 shortages. Though technical grade 

 IBA will not be labeled for direct 

 nursery use, most registered, formu- 

 lated products will remain available. 

 Significant cost increases are not 

 expected. 



...and Approves 



Disease-controlling 



Fungus 



Reprinted from January. 1991, 

 Greenhouse Manager. 



The EPA has approved the use of a 

 naturally occurring beneficial fun- 

 gus as a biological control for two 

 plant diseases. It is the first biocon- 

 tiol fungus approved to control plant 

 disease in the United States. 



A strain of Gliodadnim virens was 

 approved as a greenhouse biological 

 control for Rhizoctonia colani and 

 Pythium ultimum, two diseases that 

 cost growers more than $1 billion a 

 year, reported W. R. Grace & Co., 

 exclusive licensee for the fungus. The 

 company said it may seek approval 

 for the outdoor use of the biocontrol 

 fungus as well. 



The USDA's Agricultural Research 

 Service invented and patented the 

 technologv for formulating Glio- 

 ladium into pellets. Grace, working 

 in cooperation with ARS scientists, 

 further developed the technology 

 and hopes to have the product on the 

 market in two years.

The meeting began at 7: 15 in the classroom off the Thompson School greenhouses 

 in Durham. Jennifer, Chris, Tom. and Richard were there. Last month's minutes 

 and the financial report were read and accepted. 



Because this year's expenses were more than the revenues, finances were again 

 a major topic. Although strict economy and the hiring of a new designer cut $300 

 from The Plantsman production costs (the October/November issue was $1730; 

 the December/January issue was $1440), more revenue is needed to maintain the 

 present format. After some discussion, the board decided to double the ad rates 

 (even these new rates are quite a bit lower than those of most publications). This 

 takes effect in January. The board reahzed that there might be fewer — or 

 smaller — ads, but hoped that the overall income would be larger. 

 Winter meeting plans were finalized. 



Applications for this year's NHPGA scholarships from eight UNH Thompson 

 School and five Department of Plant Biology students were carefully read and 

 thought over by the board members. Sandra Edwards and Robert Baron were 

 chosen to receive the awards. 



There was some discussion about how to improve the application forms and give 



board members enough time to check applicants more thoroughly if they chose to 



do so. Some of the suggestions will be tried next year. 



The board decided to meet in Laconia on January 17 just after the NHPGA Winter 



Meeting and to invite the hosts of the NHPGA Summer Meeting to the board 



meeting on February 6 to begin making plans for that event. 



The meeting adjourned at 9:15. 



Resembling granular fertilizer, the 

 pellets are made of dormant fungal 

 spores, wheat bran, and alginate — a 

 natural gel -like material that binds 

 the particles together. When the pel- 

 lets are moistened, the spores germi- 

 nate and the fungus multiplies and 

 controls the two fungi which cause 

 dampening-off diseases.

Successful Genetic 

 Modification 



Reprinted from December 1990, 

 GrowerTalks. 



Florigene B.V., Aalsmer, Holland, 

 succeeded in modifying the flower 

 color of a chrysanthemum through 

 genetic modification techniques. By 

 introducing the chalcone synthase 

 gene, one of the genes responsible for 

 pigment production in petals, the 

 flower color of the chrysanthemum
