Managing Cercospora in Beet

Cercospora leaf spot can significant losses in beet if not controlled properly.

Cercospora on beet.

Cercospora leaf spot on beet. Note the round tan leaf spots with dark red margins.

The fungus overwinters in soils and be a continual problem in fields with short crop rotations. It has developed resistance to important fungicides in beet production areas in the US and abroad. Resistance has been detected in the Benzimidazole fungicides (FRCA code 1); the DMI fungicides (Tilt, tebuconazole; FRAC code 3) and the strobilurin fungicides (Quadris, Cabrio, Headline; FRAC code 11). Beet growers in NJ who have relied heavily on, and are not obtaining adequate control of Cercospora with either DMI or strobilurin fungicide applications in their weekly programs should discontinue their use. These growers should switch to fungicides with different modes of action such as Fontelis (penthiopyrad, 7) at 16.0 to 30.0 fl oz/A (3 day PHI) and Merivon (fluxapyroxad + pyraclostrobin, 7 + 11) at 5.5 fl oz/A (7 day PHI). Growers who are still obtaining adequate control with either the DMI or strobilurin fungicides can continue their use, but should make efforts to incorporate the use of the mentioned fungicides above to help reduce the chances for resistance development.

Late blight Found in Cherry Tomato in Cumberland County – 9/26/14

Late blight has been found in small cherry tomato field near Roadstown, NJ today where 100% of the field is affected. This is the third report of Late blight in New Jersey this year and the first since 9/8.

Cool day and night temperatures with prolonged dews are ideal for Late blight development, especially in fields where no protectant fungicides have been applied in recent weeks.

All growers who are still in tomato production should continue to scout on a regular basis and apply protectant fungicides. Abandoned commercial fields, need to be disked under or  sprayed with gramoxone to kill all living tissue. All abandoned organic fields should be disked under or plants should be pulled and discarded.

Volunteers Needed for Brown Marmorated Stink Bug Count

Scientists at the USDA are conducting a second year of the “Great Stink Bug Count” and are looking for volunteers from NJ! They are trying to identify characteristics of houses that brown marmorated stink bugs look for when finding overwintering sites. Last year’s count had over 200 volunteers with 44 individuals who counted every day.

BMSB OW

The basics:

  1. Fill out the form
  2. Count the BMSB on the exterior of your home each day
  3. Enter in your count data

Consider participating in the 2014 Great Stink Bug Count!

September 15 – October 15, 2014

You can download particpant forms here: http://www.stopbmsb.org/2014-count

Results from 2013 are the first to document factors that may be important in where bugs chose to overwinter. Last year’s results suggest that landscape factors, specifically agriculture and woodland habitats, may have the greatest influence on the number of BMSB overwintering on a house.

This data will go a long way to helping us figure out important steps to managing BMSB. They are looking for citizen scientists to help out! Please fill out the attached form and send it in if you are interested!
