8/27 Lunchtime Webinar - Using Biological Control and Pesticides Together to Manage Greenhouse Insect and Mite Pests: Can it be Done?

Please join us for this August lunchtime greenhouse webinar. Dr. Raymond Cloyd, Professor of Entomology and Extension Specialist, Kansas State University will discuss the fundamentals of integrating pesticides (insecticides, miticides, and fungicides) with biological control agents (parasitoids and predators) to mitigate problems with insect and mite pests. He will discuss the direct and indirect effects of pesticides on biological control agents and provide examples of situations where both pest management strategies may be integrated. Raymond will include information based on scientific research conducted in his laboratory at Kansas State University.

MA Residents Asked to Report Receipt of Any Unsolicited Packages of Seeds

According to a July 28, 2020, press release from the Massachusetts Department of Agricultural Resources and Executive Office of Energy and Environmental Affairs, residents of Massachusetts who receive or have received an unsolicited package of seeds should not plant the seeds and should contact state plant regulatory officials using a form on MDAR’s website.

For more information: https://www.mass.gov/news/massachusetts-residents-asked-to-report-receipt-of-any-unsolicited-packages-of-seeds

For Massachusetts residents – Please submit a report to the MA Dept. of Agricultural Resources at: https://www.mass.gov/forms/receipt-of-unsolicited-seeds

For residents of other states – Please contact your specific state's State Plant Health Director. ( SPHD Search: https://www.aphis.usda.gov/aphis/ourfocus/planthealth/ppq-program-overview/ct_sphd )

National Tomato Brown Rugose Fruit Virus (ToBRFV) Greenhouse Survey

As a follow up to the initial find of ToBRFV in Florida back in December 2020, the USDA is now requiring an emergency survey for ToBRFV in all states. As a result, the Massachusetts Department of Agricultural resources (MDAR) is seeking to determine the location of commercially grown tomato, pepper, or eggplant, at high yields, under a structure (not field grown) in MA. Plants can be either fruiting or not yet fruiting hosts (not just for seedlings as before), and includes plants intended for local distribution as well as non-local. These sites will need to be surveyed by MDAR staff as soon as possible.

Growers should contact Joanne Klein directly at [email protected] or call/text at 857-324-3404.

UMass Soil Testing Lab Update

The UMass Soil and Plant Nutrient Testing Lab is pleased to announce that we will be accepting new orders for ROUTINE SOIL ANALYSIS and PARTICLE SIZE ANALYSIS orders ONLY beginning Monday, 7/13/20. Please do not send orders for other types of analyses at this time. Orders should be sent via USPS, UPS, FedEx or other private carrier. The lab office will remain closed to the general public until further notice. Hand delivered orders will not be accepted at this time. Processing time will be longer than usual since we are operating with reduced staff and staggered shifts. Updates and order forms are available at: https://ag.umass.edu/services/soil-plant-nutrient-testing-laboratory.

Paycheck Protection Program (PPP) Updates

The Paycheck Protection Program (PPP) has reopened the application period until August 8, 2020. The PPP original application period closed on June 30, 2020.

As a recap, PPP is a program administered by the U.S. Small Business Administration (SBA) with applications being processed through an SBA-approved lending institution. While PPP is a loan, an important point to note is that the loan will be fully forgiven if the funds are used for payroll costs, interest on mortgages, rent, and utilities (at least 60% of the forgiven amount must have been used for payroll). Forgiveness is based on the employer maintaining or quickly rehiring employees and maintaining salary levels. Forgiveness will be reduced if full-time headcount declines, or if salaries and wages decrease. The period used to cover eligible costs and expenses has also increased from 8 weeks to 24 weeks from loan disbursement, making it easier for PPP recipients to meet the 60% payroll requirement. Special consideration under PPP is provided for seasonal businesses such as farming, nursery, greenhouse and aquaculture operations.

More detailed information, including a list of SBA-approved lending institutions that process PPP applications can be found at: https://www.sba.gov/funding-programs/loans/coronavirus-relief-options/paycheck-protection-program#section-header-5

Are Your Tulips on Fire?

Cool, wet weather this spring has been highly conducive to development of the disease known as tulip fire, caused by the fungus Botrytis tulipae. Symptoms include distorted leaves and small, oval-shaped, tan-colored lesions with dark borders on leaves and flowers. Lesions may coalesce, affecting large areas. Lesions on flower stems often cause them to collapse and infected flower buds may fail to open. Fuzzy gray sporulation appears on necrotic tissues. The spores are dispersed by wind and can cause secondary infections as long as environmental conditions are conducive to disease.

Tiny black resting structures called sclerotia may be seen on the lower ends of severely affected leaves and on the surface of bulbs. Sclerotia remain viable in the soil for many years and act as a source of infection when shoots emerge from bulbs each spring.

Once an infection has taken hold in a planting, disease will likely be more severe in each successive year.
Remove dead tree/shrub leaves from the garden in spring to decrease humidity around emerging tulips; remove affected tulip leaves and flowers frequently as they emerge and dispose of them off-site. Avoid working with plants in wet weather. A three-year rotation is recommended. In large landscape plantings, protective fungicides may be applied when the weather is predicted to be cool and damp.

TOMATO BROWN RUGOSE FRUIT VIRUS (ToBRFV) - YOUR INPUT IS REQUESTED

Tomato Brown Rugose Fruit Virus (ToBRFV) is an emerging disease issue in greenhouse tomato crops worldwide. In support of the tracking and management of this issue, USDA APHIS is currently seeking to gather information about tomato seedlings (transplants) produced in greenhouses for re-sale. If this something that your business is involved in, please send the following information to Joanne Klein of the Massachusetts Department of Agricultural Resources at [email protected]:

- Location of tomato seedling production for resale
- What time of year production begins
- Approximate number of plants

For further reference, UMass Extension has a new fact sheet about Tomato Brown Rugose Fruit Virus at https://ag.umass.edu/greenhouse-floriculture/fact-sheets/tomato-brown-rugose-fruit-virus-tobrfv. Links at the bottom of the fact sheet provide further information about mitigation steps that have been implemented to date by the USDA and others.
