Manitoba crop report: weather delays haying

Manitoba’s crop report for the week ending August 5 showed delayed haying some regions due to wet conditions and some delayed crops that hadn’t yet made up for the late and cool spring.

In the Southwest region there was general rainfall in the south west with variable amounts from 10-35 mm. Some storm systems travelled through the area with high winds and hail, but very little damage reported.

South of Highway # 1 crops progressed well with cereals done flowering and starting to fill. Most canola is finishing bloom. Sunflowers are starting to flower, however several weeks are required to reach maturity. The majority of winter wheat has been desiccated with harvest expected later this week. Fall rye may be cut this week and peas will be desiccated.

North of Highway #1 cereals continue to develop with the majority now filling. Canola is approximately 50% done flowering the remainder is in the late flower to full bloom. Flax continues to flower, peas are done flowering and starting to fill, some winter wheat will be desiccated this week. Pastures are in good condition, first cut hay is about 60% complete with average to below average yields.

Overall cropping concern is a lack of heat to bring crop to maturity. No major insect problems at this time.

In the Northwest there were isolated thundershowers with some light hail reported in the Dauphin area. Humidity remains high and producers continue to struggle with the hay harvest which is estimated to be 80 per cent complete.

Some haying progress was made but hay producers near Lakes Winnipegosis and Manitoba are at a standstill because of rain combined with high winds moving waves onto shore causing flooding to native hay fields. Hay quality is average and yields are reported to be approximately 1.5 – 2 T/ac. At this point in the grazing season, pastures are reported to be in good condition.

Some crops in the Ste Rose area are suffering from excessive moisture and haying is behind schedule.

About 55 per cent of wheat is at the dough stage; barley and oats are slightly behind. Dauphin and Ste Rose areas report fusarium in wheat and barley. Canola is well podded with good seed development. No reports of serious insect activity in either cereals or canola. A few diamondback larvae have been reported in canola as well as localized grasshopper activity.

in the Central region, most of the area saw scattered showers, ranging from 4-15 mm. Somerset/Pilot Mound area received the highest accumulations at 25-35 mm; hail was reported in the Treherne area. High winds caused some crop lodging. Temperatures remained normal to cooler than average for the week. Although some crops still struggle due to excess moisture and cool conditions, many areas would welcome some rain for crop filling.

Canola is podding well. Most flax is in the boll stage and filling. Soybeans and edible beans continue to flower; podding has started. Preharvest applications are near complete on winter wheat, and have started in the early spring cereals. Winter wheat harvest should start this week, weather permitting. Early yields in two or three fields in the south are running 70-80 bu/ac. Spring cereals continue to fill, and the earliest fields are turning. Corn continues to tassel; some fungicide applications are being made. Majority of sunflowers are blooming.

Bertha armyworm monitoring continues; no reports of crop damage at this time. A few fields have higher numbers of diamond back moth larvae, and monitoring continues. Grasshopper activity is being monitored, and some headlands and hot spots are being sprayed. Some spraying for sunflower beetle larvae is being done, high numbers of lygus are reported in confectionary sunflowers, and control is targeted. Damage due to sunflower bud moth is evident at higher levels than average. Aphids in some flax fields are nearing threshold levels, and control measures may be necessary. Soybean aphids are also being monitored, and some fields may be treated.

Haying continues, with rains delaying baling. Yields are expected to be average to lower than average for most fields. Somerset/Pilot Mound report fair to poor re-growth for second cut, as well as pastures, due to dry conditions. Recent rainfall in the area was very welcome. Pasture growth is good to adequate in most areas. Morden area reports second cut alfalfa at 1.5-2 T/ac; as good as first cut.

Dugout levels are adequate. Areas that haven’t received rain are looking for precipitation. All areas are hoping for warm temperatures.

In the Eastern part of the province last week some winter wheat and timothy seed fields were swathed. Fields of spring cereals accelerated turning last week with spring wheat and oats at the hard dough stage and moving quickly towards being ripe. Some swathing or pre-harvest treatments on wheat and oats will begin this week if the weather permits.

Fusarium head blight is noted in many spring wheat fields and potentially severe infestations have been observed in fields that did not receive fungicide treatment. Last week, most barley advanced to being ripe enough for swathing or pre-harvest treatments.

Canola, with the exception of some reseeded fields, finished flowering early last week and continued pod filling. Lygus bug numbers continue to exceed economic threshold levels in some fields and spraying continues. Flax is in the green boll stage and flowering has ended. Aphid populations in flax are found to be approaching economic thresholds. Soybeans are flowering with lower pods beginning to fill. The presence of soybean aphid is noted but levels are well below threshold.

Corn is tasseling with plants 125-150cm high in many fields. Sunflower inflorescences are open. The presence of sunflower bud moths, sunflower beetles and lygus bugs is noted. Some spraying for lygus bugs occurred. Some growers also sprayed for sunflower beetles that were causing excessive defoliation. Most winter wheat is ripe enough for swathing or pre-harvest treatments.

Hay crop condition is rated fair as the second cut continues. Second cut pure stand alfalfa yields are around 2 T/ac while alfalfa/grass yields are around 1.75 T/ac. Showers continue to make quality forage a challenge. Pastures condition is rated as good.

Soil moisture conditions are rated as good but localized problems with saturated fields or even dryness still exist. Rainfall accumulations are very erratic across the region with some areas receiving over 35 mm of precipitation while others only received light showers. Biggest cropping concern remains to be the weather. Continued warm, sunny seasonal conditions that last for longer than a week are necessary to preserve yield potential and accelerate crop development, particularly in corn, sunflower and soybean.

In the South Interlake rainfall varied from 12 mm in the Stonewall-Warren area to 54 mm around Selkirk. Seasonal temperatures were experienced resulting in good development.

All annual crops look very promising for yield but there is concern about slow pod development on the soybeans and cob development has just started on corn. It is estimated corn cob development is two weeks behind last year.

Desiccation of winter wheat was general with farmers expecting to start harvest late this week. Yields look very promising with low levels of fusarium evident. Low levels of fusarium present in spring wheat fields as well. Some fall rye fields have been swathed in the Selkirk area. Some barley will be swathed late this week in the Balmoral area. Canola finished flowering early last week and the majority of flax has just finished flowering.

Haying progress depends on field access. On the well drained soils, cutting of second cut alfalfa around Stonewall is resulting in good yields. A lot of second alfalfa is expected this week. Haying progress on the marginal/poorly drained soils is at a standstill due to excess rain. Some cattle producers have not started haying due to excess moisture.

In the North Interlake, rainfall varied from 23 mm in Arborg to 80 mm in Gypsumville, Fisher Branch, Hodgson, Vidir and Ledwyn districts. The rain lodged cereals and hail was reported in isolated areas.

There is major crop damage, reduced yield potential and disease pressure from excessive moisture to the majority of the North Interlake; include Gimli, Arborg, Riverton, Fisher Branch and Gypsumville areas.

Haying progress came to a halt following huge rainfalls early last week. Livestock producers are unable to access hay fields due to either saturated soils or standing water. There is a large percentage of cattle producers unable to start cutting hay as they are not able to access their fields. It is estimated that over 40% of the first cut hay has not been cut east of Arborg. Also west and north of Arborg there has been either no hay cut or what has been cut has been in the swath for over three weeks.

In the Ashern – Gypsumville area over 80 per cent of the native hay is not accessible. Winter wheat is loaded with fusarium infected heads and maturing to the point where it will be ready to swath this week if fields are accessible. Custom applicators in the Arborg area feel that many winter wheat fields will have to wait 7-10 days of dry weather before conditions allow for field operations.

Leaf diseases are present on all cereals and fusarium levels appear to be high in spring wheat as well as the barley. Spring wheat and barley have good yield potential but quality is a huge concern. Canola generally doesn’t look good due to the repeated excessive rainfall events in the North Interlake and any reasonable yield potential may be lost. Concern exists over been able to access canola fields for swathing in two weeks time.
