Experiencing Strange Symptoms on Lavender? Lavender Crop Update July 10, 2020

Lavandula angustifolia cultivars are in full bloom in most of Ontario, with lavandins starting to bloom further south. Some cultivars are already past peak, progressing through bloom faster due to the hot conditions. It is becoming very dry in most of southern Ontario, except for localized areas that have received thunderstorms. During full bloom, the moisture needs of lavender are the highest and restricted moisture can cause petals to not fully open or wilt in the middle of the day, reducing the appearance of the lavender for agritourism. Irrigation will help reduce this stress and is important for ensuring a quick transition to vegetative growth after bloom. Continue reading

Ginseng Crop Update – Pre-Plant Nematode Management – June 24, 2020

Ginseng Crop Update

Alternaria remains the biggest challenge for most growers. The problem stems from freeze damage/stunting in May and ideal weather conditions for Alternaria – hot and dry with long dew periods. With insufficient rains over the past few weeks, except in localized areas with thunderstorms, it will be very important to ensure fields are irrigated adequately to reduce stress on the plants as much as possible. If you have overhead irrigation, it is best to irrigate early in the morning or late in the evening, so you are not extending the leaf wetness period and increasing infections with Alternaria.

Suspect you have herbicide resistant weeds? Participate in a genetic testing sampling project.

By Kristen Obeid, OMAFRA Weed Management Specialist – Horticulture

Do you suspect that you have herbicide resistant weeds on your farm?  If so, why not get them tested for free through a genetic testing sample project.  So far there are 16 (5 more in progress) genetic quick tests to assist in identifying herbicide resistance in 12 weed species.  Some of these tests were implemented from scientific literature. Two are new discoveries.  These tests deliver a diagnostic and a recommendation to the grower within the same growing season.  Traditional resistance testing in the greenhouse can take from three months to a year to get results back to growers.  Now, leaf tissue instead of seed is collected.  DNA is extracted from the leaf tissue to determine if there is a change in the sequencing resulting in a mutation conferring resistance.

Understanding the Value of Fertilizers and Supplements for Specialty Crops

Growers of all crops are bombarded with advertisements and salespeople selling a wide range of fertilizers and supplements. For specialty crop growers there is added uncertainty given the limited research specific to these crops on all aspects of fertilization. As a starting point, it is important to understand the different types of products, the purpose of each within a fertility program, and the actual value or cost-benefit of applying each product. Continue reading
