Vegetable
Weed Control by Bradley A. Majek, Ph.D., Specialist
in Weed
Science. From
Plant and
Peppers - Cold
weather earlier in the season may result in abnormal growth of peppers during
the next few weeks. Low temperatures can injure tiny leaves in the growing
points. When these leaves grow out in a few weeks, they may exhibit a variety
of epinastic responses that resemble virus or 2,4-D drift injury. Leaves make be crinkled, stretched, the midvein may be shortened, and/or the leaves may appear
otherwise abnormal. The response can be very variable. Night temperatures after
transplanting need not drop to freezing to cause this injury. Night
temperatures in the upper thirties and even forties can affect “soft” plants
just out of the greenhouse.
The plant will outgrow the problem in time.
Postemergence Herbicide Crop Tolerance by
Bradley A. Majek, Ph.D., Specialist in Weed Science
The recent extended period of cloudy weather and high soil
moisture may have resulted in certain crops growing rapidly and developing a
thinner than “normal” wax layer, called the cuticle, on the leaves. This
thinner cuticle is more easily penetrated by postemergence
herbicides. Warm temperatures during the cloudy moist period will increase the
speed of growth and the thinness of the cuticle.
To reduce the risk of crop injury from postemergence
herbicides this week:
1. Reduce the amount of spray additives used to the minimum
labeled amount.
2. Use nonionic surfactants instead of oil concentrates when the
herbicide label gives you a choice.
3. Do NOT add any surfactant, oil concentrate, or other additive
if the label allows application alone.
4. Do NOT add liquid fertilizer to the spray solution, even if the
herbicide label suggests it as an option.
5. Delay treatment of crops that are marginally large enough to
treat according to the herbicide label.
6. Delay treatment until the crop has experienced 3 to 5 days of
bright, clear, warm, and sunny weather before applying postemergence
herbicides. The cuticle thickens when the weather turns warm, sunny, and dry. ❏
Crop
Reports
Insect heliotraps are out for European Corn Borer and Corn earworm. Two beet armyworm traps
are in the field. So far no insect moths have been caught in
Planting transplants of muskmelons and watermelons and some seeded
vine crops. First planting of pepper & tomato transplants
in the ground. Plants are growing. Earlier plantings are being trellised
and are beginning to form fruit. Later planting of tomato transplants will be
transplanted in mid-late June. Suspect that we are 10-14 days behind the normal
season.
Sweet corn continues to grow but could use warmer weather like
rest of the warm loving vegetables. Showers are still quite scattered, most of
the county received less than one quarter inch of rainfall since Saturday
morning. Good shower on Friday, May 20 approximately one half inch
rainfall received.
In our area most of the sweet corn that was put in the ground in
mid April is still only 2-3 inches tall. The corn that was planted the first
week of May is quickly catching up to it. The only exception is where
sweet corn was planted under plastic - that corn is about 8 inches tall. There
has been little damage except for light slug damage and cutworm/sod webworm
leaf feeding. We also have vine crops and tomatoes under row cover with
tomatoes starting to blossom and zucchini that should start to blossom next
week. We have been seeing flea beetles on cole
crops, potatoes and sweet corn as well as
cucumber beetles in the vine crops. We are also starting to find bean
leaf beetles and onion thrips. With temperature
expected to be in the 70's and 80's next week, growers are looking at putting
pumpkin seed in the ground as well as getting more tomato, pepper and eggplant
transplants put out. Soil temperatures at the 2" depth have been
near 60 for the past week.
Planting of truck crops is well underway in Northwest,
New
Farmer’s Market in Akron Inviting New Participants
A new farmer’s market will begin this summer in
The first Countryside Farmers’ Market is located on Heritage Farms in
This market, the Akron Farmers Market will begin on June 30th and
run every Thursdays from
Countryside Farmers’ Markets are “producers only” markets, which
mean that all goods sold at the market are homegrown and handmade. Vendors are
currently needed, and preference is given to local people, farmers,
organizations, and businesses that are sustainably
conscious. No brokerage is permitted; our vendors may be inspected to
ensure that their products are produced on their farm site. Vendors of
our markets can request to participate weekly, every-other week, or
occasionally. Our markets offer customers high quality, sustainably
derived local and seasonal foods, art and crafts, information, and
entertainment for the whole family. CVCC’s
markets stimulate the local economy by increasing public interest and awareness
about the importance of supporting local products, organizations, farms, and
businesses.
