A MINI-DENDROBIUM 



(Greenhouse Manc^er, August, 

 1991) 



Researchers at the University of 

 Hawaii at Manoa have developed 

 'Cathy Beck,' a miniature, seed- 

 propagated dendrohium orchid for 

 potted plant production. 'Cathy 

 Beck' flowers only 18 months 

 after germination, with the average 

 height of pseudobulhs slightly under 

 2 inches at first flowering. After 

 two years, plants remain short, with 

 the tallest pseudobulh averaging 

 about 6 inches. 



Flowers average about 1 inch in 

 length and 1 1/2 inches wide, with . 

 relatively narrow petals and sepals. { 



The half-life of sprays (from the 



opening of first flowers until 50 

 percent of flowers wilt or drop) av- 

 erages about 60 days. Flowers most 

 often appear October to February.

INSECTS THAT CONTROL 

 THRIPS... 



(Greenhouse Manager, August, 

 1991) 



Hypoaspis, a soil-dwelling mite with 

 a voracious appetite for fungus gnat 

 larvae and thrips," soon will be 

 available to US growers. The ben- 

 eficial insect produces about one 

 generation a week. Dave Marshall 

 of Northern Biologicals said his 

 company is the only one in the 

 country that has an EPA permit to 

 sell them. For more: Northern

...AND PLANTS THAT 

 REPEL MOSQUITOES 



(Grotf erTaUcs , August, 1991) 



A mosquito-fighting plant called 

 Citrosa "is a plant whose time has 

 come." Developed by Dutch scien- 

 tist Dirk VanLeeni, the Citrosa 

 plant IS the result of 13 years of 



combining plant tissue cultures to 

 produce just the right insect repel- 

 ling power — one leafy, lemon- 

 scented Citrosa protects you from 

 bites for up to 100 feet, indoors or 

 out. One plant per room or one 

 every 5 to 10 feet in your garden 

 or patio should ensure you a bug- 

 free summer.

ROUGH BROTHERS— 



New Coordinator... 



Rough Brothers national sales 

 manager Joe Tirschek recently 

 announced the appointment of 

 Sebnna Lovensheimer to Sales 

 Coordinator. 



"Sebnna will be our primary customer 

 contact person when someone is 

 interested in the status of an order or 

 quote, including catalog orders and 

 accessory quotes," Tirschek said. 



Lovensheimer is a graduate of 

 Eastern Kentucky University and 

 holds a degree in accounting and 

 business management. Collateral 

 duties include preparation of green- 

 house bench, venting, and heating 

 quotes, as well as coordination of 

 communication between distribu- 

 tors, salesmen, customers, and pros- 

 pects. We wish Sebrina success in 

 her new position. 



...and an Award 



Rough Brothers was recently pre- 

 sented with a "Supplier Champion" 

 award by one of the largest com- 

 mercial flower growers in the coun- 

 try, Yoder Brothers of Barberton, 

 Ohio. 



The award was given in recogni- 

 tion of Rough's quick response to 

 the repair of 11,000 panes of glass 

 shattered by a hailstorm at Yoder's 

 Pendleton, South Carolina, facility 

 in late April. Quick protection of 

 the crops — then at a critical point 

 in their growing cycle — and the re- 

 placement of all the glass within 

 three weeks allowed Yoder to fill 

 all their customer orders on time. 



NEW PRODUCTS— 



Preclude (TM)... 



The first insect growth regulator in 

 total release form has been intro- 

 duced by Whitmire Research Labo- 

 ratories, according to Jeff Martin, 

 Sales and Marketing Manager, Hor- 

 ticultural Division. 



PT 2 '00 (R) Preclude (TM) 

 breaks the whitefly life cycle by 

 preventing immature insects from 

 maturing into reproductive adults. 

 The active ingredient — 

 fenoxycarb — acts on the hormonal 

 system of the young whiteflies. It 

 IS also effective in control of scale.

....And Isolite 



Isolite IS a porus ceramic which can be 

 used to modify soils in order to create 

 more favorable growing conditions. 

 Basically, it decreases compaction and 

 can hold water, releasing it to the plant 

 when needed, for longer periods. Made 

 of diatomaceous earth combined with 

 natural binders rotar>' kiln fired at 1000 

 degrees C (1800 degrees F), the result- 

 ing material is guaranteed not to break 

 down — ever — in soil.
