Onion Crop Growth Stage and Status Last Modified: 07/27/12

The harvest of the spring-sown crop is proceeding well. Yields and quality should be good as

environmental conditions have been ideal. Some delays in harvest may occur due to wet fields.

Market prices have increased due to reduced supply. An additional sentinel plot has been

harvested with only one remaining. The last remaining sentinel plot will be harvested before the

next sampling date. Depending upon the location, the harvest of the spring-sown crop should

conclude in the next 2-3 weeks. This is the last report.

 

Weather Impacts (temperature, rain, hail, freezing) Last Modified: 07/27/12

Summer monsoon conditions continue with decreased temperatures and sporadic rainfall. This

rainfall may have resulted in some wet fields and a delay in harvest depending upon the location.

Since the start of the month, rainfall totals have averaged 1-3” depending upon location.

Onion Crop Growth Stage and Status Last Modified: 07/27/12

Onion bulbing dominates growth in most fields with crop in growth stages 6 or 7.  Growers have

sufficient water to deal with irrigation needs and no water shortages noted.  Growers report few

problems but indicate that they are regularly applying insecticides for thrips control.

 

Weather Impacts (temperature, rain, hail, freezing) Last Modified: 07/27/12

Tropical moisture flow out of SW USA dominated weather conditions in Utah over last two

weeks. Rain showers around in northern Utah occurred but very localized and less than ½ inch

reported.  Day temperatures were near normal with temperatures in low 90’s.

Onion ipmPIPE Project

onion 2

The ONION ipmPIPE was developed in response to stakeholder demands for a coordinated and comprehensive website where onion farmers and agricultural professionals could obtain: 1) real-time information on the distribution and severity of priority diseases and insect pests in North America; 2) time-sensitive disease risk assessments; 3) information on disease and insect pest management options and 4) links to other important tools on onion production and pest management.   Stakeholders are advised of the status of priority diseases and insect pests through observational maps and national/state commentaries on a public website.  This allows all state commentaries/observations within reach in one website.

Emphasis is on  Onion (green, transplanted, seeded, storage, processed); and other alliums such as garlic & chives benefit from research on pests and diseases.  Priority Diseases and Insect Pests include: Iris yellow spot virus (IYSV); Thrips (emphasis on onion thrips) – as a vector of IYSV and a pest;  Other insects such as onion maggot;  Foliar & storage fungal diseases including Botrytis, Purple Blotch, Downy Mildew, Blue Mold, Black Mold; and Foliar & Storage bacterial diseases including Xanthomonas Leaf Blight, Sour Skin, Slippery Skin, Pantoea, Soft Rots.

A national team of onion experts, growers and industry representatives have created a unique on-line resource that will enhance the production, pest management, storage, and marketing of this vital food product for the consuming public in the United States and internationally.  This multi-year project is funded in part by the USDA’s Specialty Crop Research Initiative established by the 2008 Farm Bill; and has been endorsed by state and national onion organizations throughout all major onion-producing regions of the country.

Onion Crop Growth Stage and Status Last Modified: 06/15/12

Onion growth is strong with most planting in the 7th leaf stage.  Growers have been irrigating as

weather has been warm and dry.  Growers report few problems with weeds and early season

management has been surprisingly successful. Most are very happy with crop progress so far.

 

Weather Impacts (temperature, rain, hail, freezing) Last Modified: 06/15/12

No rain in northern Utah in last two weeks.  Overall day temperatures about normal during last

two weeks with no hot temperatures though there was some very cold mornings during the

weekend of 8-10 June. Storms brought some high winds but no damaging weather like heavy

rains or hail.

 

Insect Scouting, Outlook and Management Last Modified: 06/15/12

Thrips

Surveys completed during the last two weeks reported that thrips identified in all fields

evaluated.  Thrips populations still very low in most fields with counts in the range of 1-2 adults

and 1-4 larvae per plant.

Onion Crop Growth Stage and Status Last Modified: 06/15/12

The harvest of the autumn-sown crop is more than halfway complete. Environmental conditions have been ideal for harvest and curing. High temperatures and winds have caused onion varieties to mature earlier than they might have. Market prices could be higher. The spring-sown crop is progressing well. Up to this point, environmental conditions have been ideal for growing the crop. Depending upon the location, plant stages range from 7 to 11 true leaves per plant with those earlier maturing cultivars producing the largest plants. Some bulb initiation has occurred. Crop development is on track to start harvesting in July.

 

Weather Impacts (temperature, rain, hail, freezing) Last Modified: 06/15/12

Weather conditions have been normal for this time of year. Days are sunny with very little cloud cover and no rainfall. The daily maximum temperatures have averaged in the mid 90s. Temperatures are forecasted to be higher next week.

Onion Crop Growth Stage and Status Last Modified: 06/05/12
The autumn-sown crop is currently being harvested. Bulb yields and quality should be good as
environmental conditions have been ideal. Market prices could be higher than currently. The
spring-sown crop is progressing well. Up to this point, environmental conditions have been ideal
for growing the crop. Depending upon the location, plant stages range from 6 to 10 true leaves
per plant with those earlier maturing cultivars producing the largest plants. Some bulb initiation
has occurred. Crop development is on track to start harvesting in July.
Weather Impacts (temperature, rain, hail, freezing) Last Modified: 06/05/12
The daily maximum temperatures have returned to normal (mid 90s) for this time of year. In mid
May, there were three days of rain that broke a 2.5 month lack of rainfall. During those rainfall
events, some hail caused damage to onion fields in the Hatch growing area. Both the autumnand
spring-sown crops should recover there. Since that time, there has been no rainfall with none
forecasted for the next ten days.

Utah Commentary
Onion Crop Growth Stage and Status Last Modified: 05/18/12
Onion growth is strong with most planting in the 4th leaf stage; approximately 1,500 acres in production in Davis, Weber and Box Elder counties in 2012. Field sites getting drier and growers have applied 1st and 2nd herbicide applications (Goal and Buctril). Weed management very good as weather conditions favorable for most field operations.
Weather Impacts (temperature, rain, hail, freezing) Last Modified: 05/18/12
The northern Utah has received very little rain in last two weeks. First rain occurred on 5-18 with approximately 1/3 inch in Davis county and upwards of ¾ inches in northern onion production areas of Box Elder Co. Overall temperature conditions good with days in 70-80’s and nights in 40-50’s. No damaging weather related events in last two weeks.

COLORADO Commentary
Onion Crop Growth Stage and Status Last Modified: 05/16/12
Onion plantings complete in eastern, southern and western Colorado; approximately 7,000 acres
were planted statewide in 2012. Warm, dry conditions persist throughout Colorado, with
required irrigation with well water (salinity potential) until canal system is charged.
Weather Impacts (temperature, rain, hail, freezing) Last Modified: 05/16/12
The northern region has received very little rain in recent weeks, and other regions of the state
received less than 0.25 inches or no rain. Some regions experienced low night temperatures (mid
to upper 20) in April; and this could influence the incidence of bolting in some transplanted
varieties during bulbing.
