FROM AROUND THE STATE


ISSUE 5  June 1, 2000

 

North-Central ND

    Most of northwest and north central NoDak had general rains of 0.40 to 1 inch last Friday (May 26).
Crop conditions are good across the area. Seeding of all crops should be winding down by next week.
There are scattered reports of some fields having to be reseeded due to volunteer grain problems. Primarily,
in early seeded barley with volunteer spring wheat being the problem. Wild oats, wild buckwheat, and
Canada thistle have been the major weed problems. Winter wheat and rye are in the flag leaf stage and
should begin to head next week. Early spikelet count of winter wheat in the Minot area has 15 to 16 spikes
per head with three to five tillers per plant. Early yield estimates range from 55 to 65 bushels per acre; it's
early and a lot could change before we get the crop in the bin!

CRUCIFER FLEA BEETLE ACTIVITY IN CANOLA CONTINUES.

Flea beetles are still active on canola and some reports of foliar spraying have come in. Continue to monitor
for flea beetle damage during the next two weeks. Most of the earlier planted canola is past the susceptible
stage thou. At Minot, three distinct peaks of flea beetle activity were observed which coincides with the
warm weather periods.

RISK PLANTING WINDOW (200 -600 DEGREE DAYS) FOR THE NORTH CENTRAL
AND NORTHWEST REGIONS.

   The following insect degree days (DD), using 40"F Base, have been accumulated as of May 28, 2000:
Rollette Co., Rolla = 552, Burke Co., Columbus = 579, Bottineau Co., Bottineau = 606, McHenry Co.,
Towner = 623; Renville Co., Mohall = 630, McLean Co., Turtle Lake = 668, Ward Co., Minot = 693,
and Williams Co., Williston = 747 (Source: NDAWN).

 

APHIDS DETECTED AT NORTH CENTRAL RESEARCH EXTENSION
CENTER, MINOT.

    The first aphid was observed this week. Reports from other areas, like Carrington, confirm that the
aphids are slowly migrating into North Dakota. Relative population densities are still low.

 

SMALL GRAIN DISEASES, TAN SPOT AND SEPTORIA, HAVE BEEN OBSERVED
ON WINTER WHEAT AT
NORTH CENTRAL RESEARCH EXTENSION CENTER, MINOT.

South-Central ND

    Total rainfall as recorded at NDAWN sites in south-central ND during May 24-30 ranged from
0.36 at Carrington to 1.28 inches at Jamestown. Topsoil and subsoil moisture currently are adequate
in the region. The rainfall was especially useful for tillering wheat and germination/emergence of late-seeded
crops.

    Small grain, corn, cool-season legume, and spring-seeded oilseed stands continue to generally be in good
condition and at adequate plant densities. Some heat canker was present in Carrington-area wheat late last
week. The majority of soybean, dry bean, and sunflower acreage have been planted and planting should
be completed within a week. Winter rye is heading and winter wheat is in the boot stage. Dormant-seeded
canola at the Carrington Research Extension Center began to flower on May 25. Alfalfa cutting is in progress.

    Post-emergence herbicide application in small grain and canola continues to be a common farm activity.
POST weed control in corn and flax also has started. Wind and rainfall has hampered herbicide application.
Leaf spot disease in small grain continues to be at low levels. Flea beetle injury continues to be present in
canola, but recent cool temperatures and rainfall combined with progressive canola growth is reducing
the concern with this pest. Low populations of diamondback moths were found in traps at the Carrington
Center late last week. Also, a few aphids were found in wheat last week at the Center.

Northeastern ND

    Planting of small grains is nearly completed with only replantings occurring for the most part.

    Rainfall varied from about 0.5 inches in Towner and Rolette counties to sprinkles in Pembina, Walsh,
and Grand Forks. Pembina , Walsh, and Northern Nelson are very dry. Some stands are spotty but most
crops are OK. Some of the most advanced small grain is starting to show effects of moisture stress.

    Rye is starting to head, winter wheat flag leaves are emerging and the earliest wheat and barley plantings
are beginning to joint. Most small grain plantings are 1-3 leaf stage.

    Row crop plantings are nearly complete. Weed control questions on wild oat are common. Wireworm,
flea beetles on canola and cutworms in sunflower are ongoing concerns.
