OMAHA (DTN) -- The following are highlights from the weekly crop progress report issued June 19 from the Manitoba Agriculture, Food and Initiatives department.
-- All regions reported precipitation, with amounts ranging from 15 to 55 millimeters. In most regions, crops and pastures benefitted from these rains. Low temperatures have slowed growth of corn and soybeans.
-- Herbicide applications continue as weather conditions allow. Crops in most areas have received one herbicide application. Fungicide applications are just beginning, largely in winter and spring wheat for management of fusarium head blight and leaf diseases.
-- Iron deficiency chlorisis has been observed in soybeans in central and eastern regions, although some recovery is noticeable.
-- First-cut haying has been continuing as weather conditions allow. Alfalfa weevil has been reported in the Southwest and Interlake regions.
Breaking down more details by region:
Showers and thunderstorms brought 25 to 45 mm of rain to the region. Northern areas are in great shape, but some fields in the southwest corner are experiencing moderate moisture stress with standing water in low-lying areas. Overall most crops are benefitting from these rains. Temperatures were variable during the week.
Winter wheat and fall rye are fully heading. Producers are starting to apply fungicides to winter wheat.
Spring cereals vary in stage from tillering in the early seeded crops to 2- or 3-leaf stage in the later-seeded crops. With the exception of the later-seeded crops, herbicide application is completed.
Canola is doing well and early seeded crops have cabbaged out and covered the ground. Later-seeded crops benefited from the rain as the seed was sitting in dry ground. Most of the later-seeded crops have germinated and are in the 2- to 3-leaf stage. Flea beetles should not be a problem in canola at this time.
Corn and sunflowers continue to develop, but growth is slow due to the cooler weather. Soybeans are progressing well and the majority are in the first to second trifoliate stage. Some early seeded fields are getting their second glyphosate application.
Peas are 20 to 25 centimeters inches tall with no major issues.
Weed control measures are now 75 to 80% complete across the region.
No major insect issues as diamondback moth and bertha armyworm numbers are very low.
The frequent small showers experienced over the week will be good for hay and pasture, however, warm sunny weather is needed to bring on the forage growth. Alfalfa weevil has been reported in the Souris area.
Lower temperatures throughout the week ended off with a weekend of rain in most of the Northwest Region. Rainfall amounts varied from 32 to 55 mm in the Swam Valley area and 38 to 50 mm in the Roblin area, with ponding occurring in some fields. Dauphin received 19 to 34 mm; Ste. Rose received 19 mm and McCreary received 58 mm. The Pas received 25 mm of precipitation; soil moisture conditions in this area are excessive with fields inundated.
The majority of seeding in the North West region has wrapped up, with the exception of The Pas, where seeding remains at less than 15% complete due to excess moisture. Most of the crops continue to advance nicely in the remainder of the region. Winter cereals are at the boot stage and spring wheat is in the seedling or tillering stage. Most of the canola is in the rosette stage, but patchy emergence is seen in some later-seeded fields due to lack of moisture at the time of seeding.
Field peas, lentils, and soybeans are in the vegetative stage.
There were no herbicide applications throughout the weekend and due to wet fields spraying early in the week will be a challenge. Weed activity is flourishing in fields that have not yet had a herbicide application. Diamondback moth populations continue to be the highest in the Minitonas region; however, the count is down significantly compared to the previous week. Bertha armyworms are of no concern. There are reports of fields in the Swan Valley region with cutworm activity.
Rain over the past week was welcome for forage and pasture growth throughout the region. Haying has not begun to any extent due to the rains. There are some reports of flowering beginning on alfalfa plants in some fields. Alfalfa weevil damage was reported in the McCreary area.
Field activity was limited due to cooler weather and rain showers. Rain was welcome for most and amounts ranged from 15 to 30 mm for much of the region. Higher accumulations were seen in Gladstone, Portage, Austin, Macgregor, Treherne, Clearwater, and Cartwright at 35 to 45 mm. Some western areas are quite wet, having received higher amounts of rain over the past few weeks. Soils are saturated in some cases, with standing water in low lying and level areas of fields. Crops in areas with higher moisture are turning color, showing signs of excess moisture stress. Some reseeding has occurred in the Crystal City area, as a result of last week's hail storm.
Low wind conditions early in the week allowed a number of producers to catch up on herbicide application. Most cereals and canola fields have received one herbicide application.
The majority of cereals are growing well. The most advanced fields are in flag leaf stage and some fungicide applications are being made.
Canola is advancing well; benefiting from the recent precipitation and cooler weather. Crops are no longer susceptible to flea beetle injury. Most fields are in four-leaf stage to bolting, although some canola was reseeded last week. The most advanced fields are in early flower; some expect to apply fungicide by the end of this week. Many fields, particularly the earliest seeded canola, are stagey due to uneven emergence.
Corn growth has slowed with the lower temperatures. Some fields are looking spindly, with narrow leaves and poor color, and would benefit from warmer weather. Herbicide applications have continued; high winds and showers over the weekend created a challenge.
Sunflowers, flax and peas are growing well.
Most soybeans range from the first to third trifoliate. Majority of fields have seen first pass herbicide applications; second applications continue. Yellowing due to iron deficiency chlorosis is evident in many fields, although recovery is noticeable and some varietal differences are noted.
Fall-seeded crops in western areas with good winter survival are growing well; fall rye and winter wheat continue to flower, with the most advanced into the milk stage. Most fungicide applications have been undertaken where risk of fusarium headblight warranted.
Weed growth had been somewhat limited by lack of rainfall, but recent rains will bring on new flushes.
No major insect issues. Pest species of grasshoppers are starting to hatch. Producers may notice some in the ditches, but numbers are low and remain non-economical to spray. Diamondback moth numbers are low. Cutworms are beginning to pupate; numbers and injury are on the decline.
Pasture conditions are rated as fair on average, but range from poor to good. Grasses are heading out, and alfalfa is starting to bloom. The hay crop yield potential is estimated to be lower than normal, due to winter injury and drier conditions, although the recent rains have resulted in some improvement. Dairy producers have started haying, and more beef producers will begin as weather conditions allow. Livestock water supply is adequate.
Cool and rainy weather prevailed for most of the week across the Eastern region. Precipitation amounts varied greatly ranging from 20 to 48 mm. Significant rainfall events occurred on June 14 and 15 followed by intermittent rainfall and drizzle throughout the remainder of the week. Soil moisture conditions on cropland across the region are rated as 95% adequate and 5% surplus. Soil moisture conditions of hay and pasture land were rated at 90% adequate to 10% short.
Most fields have received a first herbicide pass. Little spraying progress was made this week due to rainfall and strong winds. Some fields that were sprayed last week may need to be done again because rainfall occurred too soon after application. It is expected that many fields will receive a second herbicide application this week if the weather allows. A significant flush of weeds are expected now that most of the region has received rain. Flag leaf fungicides are expected to begin on earliest seeded cereals by end of the week.
Last week's precipitation was beneficial for crop growth and development. Early seeded wheat is in the flag leaf stage with the remainder in stem elongation. The earliest canola is bolting with a few flowers; the rest is in the rosette/cabbaging stage. Soybeans are in the first to early third trifoliate. Some yellowing due to iron deficiency chlorosis or a period of N deficiency prior to good nodulation has been observed. The largest root crown nodules on most mature soybean plants are starting to show pink interiors indicating that N fix is proceeding. Corn is in the V5 to V7 stage and sunflowers are at V4 to V8. Reports of insect and disease issues have been infrequent, although some diamondback moths have been observed in canola fields. Overall crop condition is good to excellent and crop development is steady and relatively rapid.
Producers started cutting hay on the weekend and are hoping to start haying this week if the weather cooperates and fertilized fields look good. Livestock are doing well on pasture as native pastures are starting to be grazed. Hay fields and pasture are in 80% good to 20% fair condition. Availability of livestock water was rated as adequate.
Crops are advancing rapidly with the recent rains; rainfall throughout the region ranged from 13 to 30 mm in the last seven days. Although precipitation since May 1 ranges from 43 to 74% of normal, moisture conditions are considered good to excellent throughout the region partially due to the wet fall and winter as well as the recent rains.
In the south Interlake winter cereals are mostly headed out with little spraying of fungicide so far as it has been fairly dry up until this past week. Spring cereals are well-tillered, herbicide applications are compete and some crops will likely be sprayed with fungicides in the next one to three weeks.
Some isolated spraying for cutworms and flea beetles has occurred, however insect pressure has been fairly light. The most advanced canola is starting to bolt and fields will soon be yellow. Diamondback moth counts are low in traps and Bertha armyworm traps have been set out. Peas are at the 5- to 6-node stage and herbicide applications have been completed. Soybeans are at 1 to 3 trifoliate and will likely see second herbicide applications shortly. Many fields are yellowing due to iron deficiency chlorisis. Growers are encouraged to note varieties that are least affected by iron chlorosis, for variety selection in future years. Corn is advancing slowly, varying from the 2- to 6-leaf stage, and has seen one herbicide application.
In the north Interlake, canola varies from cotyledon to 5-leaf, and most has been sprayed once for weeds, with a few fields sprayed for flea beetle control. Soybeans are from 1 to 2 trifoliate and are exhibiting decent nodulation. Spring cereals vary from 3- to 6-leaf stage, with 1 to 3 tillers; the first herbicide applications are about 50% complete. Corn varies from 2- to 6-leaf stage.
Cooler weather and variable rains this past week have encouraged hay and pasture development. Alfalfa is in the late bud to early bloom stage. Alfalfa weevils and aphids are present in alfalfa fields and seed fields are being sprayed for these pests. First cut hay yields reported are significantly lower than last year.
Pastures are rated as fair to good condition and are supplying adequate feed for this time of year. There is adequate water for livestock to drink. Most cattle are on pasture now and flies are bothering the livestock.
