Pest Management Solutions for Specialty Crops and Specialty Uses
Greetings!
This monthly email provides information about IR-4 program accomplishments,announcements, resources and upcoming events.
Food Use Program
In April,there was one new tollerance established for Flonicamid on Sunflower subgroup 20B . To view the entire April report click here.

The 2019 residue and product performance Tentative/Scheduled Studies list is available on the IR-4 website (click here ). Preparation of all 2019 draft protocols is in progress, with many already signed. Comments and suggested DRAFT protocol revisions should be directed to the Study Director responsible for the study.  

 
The IR-4 2019 "Week of Workshops" is set for the week of Sept. 22 at the Delta Hotel Baltimore Hunt Valley, Hunt Valley, MD. The first announcement went out via email and Constant Contact April 9. Final agendas and other important information will be communicated in coming months via this monthly report and other means.
Registration is now open. To view more information and to register go to our website or register here.
International Activities
The 2019 Codex Committee on Pesticide Residues (CCPR)met during week of April 9, 2019 in Macao, China   The CCPR, agreed to forward 326 MRLs to the Codex Alimentarius Commission (CAC) for final adoption at its next session (July 2019).  These MRLs are associated with 31 pesticides. Three of the seven new compounds reviewed by JMPR in 2018 were nominated by the United States. Crop Group and Subgroup MRLs accounted for 43 of the 326 MRLs forwarded for adoption.
 
The Committee considered proposed amendments and reached consensus on the classification work for the following crop groups and subgroups: Class C: Primary Feed Commodities. Type 11: Primary Feed Commodities of Plant Origin, All Groups and Class D: Processed Food Commodities of Plant Origin. All Types and Groups. 

CCPR further developed Guidance for Compounds of Low Public Health Concerns to establish harmonized concepts and criteria to be used to identify pesticides that can be considered exempt from the establishment of CXLs. Many countries supported continued work since products of low public health concern, such as biopesticides, continue to play a more important role in plant protection.
 
The Codex schedules and priorities and the revised Schedules and Priority Lists of Pesticides for review by JMPR included: Six new compounds and twenty nominations listed for new uses, and six compounds for periodic Review.

Research Summaries
During April, we posted the summary Algal Leaf Spot Efficacy, and the crop safety summaries for pendimethalin, pendimethalin + dimethenamid-p, and prodiamine + isoxaben.
 
SCRI Protecting Pollinators
In April, we prepared a preliminary summary for EPA about the percentage of plants sold in the US that are attractive to pollinators.
 
Integrated Solutions
For the Integrated Solutions priority setting workshop, the top priorities identified were: damping-off in hemp, bacterial disease control in onions, parasitic weed control in processing tomato, cucumber beetle control in watermelon, wireworm control in sweet potato, and verticillium wilt control in eggplant. IR-4 believes that this Integrated Solutions approach, being a hybrid of the Food Use Pest Problems without Solutions research (PPWS) and elements of the traditional Biopesticide research program, will better service the needs of the IR-4 stakeholders. These priorities will serve as a roadmap for 2019, and help to address several high priority pest management voids for the grower community. We have just launched the Integrated Solutions Request Form ( http://ir4app.rutgers.edu/ir4FoodPub/IS/Is_reqForm.aspx ) . It can be found as the “Submit a Request” link near the top of the page here: http://ir4app.rutgers.edu/ir4FoodPub/IS_Search.aspx .  


Biopesticide Program
Research plans are being developed based on the priorities that were selected at the Biopesticide Workshop. In cooperation with university researchers, USDA-ARS and IR-4 Regional Coordinators, teleconferences have been held to develop studies on spotted wing drosophila in blueberry, downy mildew in organic basil, weed control screening, viruses and viroids in tomato and bacterial diseases of tomato.

Regulatory successes in 2018 included the registration of 2 new active ingredients with EPA.

KM1110 WDG is a water dispersible granule that contains the yeast Metschnikowia fructicola strain NRRL Y-27328 and prevents post-harvest decay in certain fruit and berries caused by Botrytis cinerea, Monilinia spp., and Rhizopus spp.

Pepino-mosaic virus strain CH2 isolate 1906 (Mild strain of pepino mosaic virus) for use in tomato. This weak strain of the virus is a form of vaccine that prevents the development of the disease Pepino Mosaic virus.
