Pythium Efficacy Summary from IR-4

At the IR-4 Ornamental Horticulture Program Workshop in 2009, Pythium Efficacy was selected as a high priority project to expand the knowledge and list of fungicides available to growers for these diseases. In addition to research collected through the IR-4 program, this summary includes a review of experiments conducted from 1999 to 2013 on ornamental horticulture and vegetable crops. During this time period, numerous products representing 38 active ingredients were tested as drench, foliar or soil applications against several Pythium species causing root rot and damping-off on ornamentals, and root rot, cottony leak, damping-off and cavity spot on vegetables. Pythium species tested included: P. aphanidermatum, P. irregulare, P. mamillatum, P. dissotocum, P. myriotylum, P. ultimum and P. vipa. Most trials were conducted on P. aphanidermatum and P. ultimum. Although there were insufficient data for definitive conclusions, several relatively new products that are included in the Pythium efficacy project looked promising. These were Adorn, Disarm, Fenstop, Heritage and Pageant. V-10208 also looked promising. The phosphorus acids/phosphorus acid generators (Agri-Fos, Alude, K-Phite, Magellan, Phostrol or Vital) provided mix results. Acibenzolar, BW240 and CG100 were generally ineffective. The established standards Subdue Maxx and Terrazole/Truban generally performed well. Conversely, the registered biological products Companion/QRD 713, PlantShield/RootShield and SoilGard generally looked ineffective. The data from these trials suggest that the effectiveness of some fungicides in controlling Pythium root rot may vary, depending on the species of Pythium or crop.

Are Biocontrols Compatible With Insecticides And Fungicides?

11 Jun

From Greenhouse Growers:

As an article from the Ontario Ministry of Food And Agriculture states, “The Holy Grail for an IPM Manager: a pesticide that controls all pests and is completely compatible with all biocontrol agents (BCAs). Obviously, it’s not going to happen.”

Some products can be used with biocontrols and some can’t. Biocontrol suppliers have shared the following links to help you make the right choices for using traditional controls in conjunction with biocontrols.
