Onion Crop Growth Stage and Status Last Modified: 06/07/13

The autumn-sown crop is progressing well and harvesting has begun in some locations. Bulb

yields and quality should be good as environmental conditions have been ideal. The spring-sown

crop is also progressing well. Up to this point, environmental conditions have been ideal for

growing the crop. Depending upon the location, spring-sown plant stages range from 8 to 12 true

leaves per plant and some earlier maturing cultivars are beginning to bulb.

 

Weather Impacts (temperature, rain, hail, freezing) Last Modified: 06/07/13

Temperatures have increased to the high 90s, but this is normal for this time of year. The

temperatures have been ideal for onion growth. There has been very little rainfall, although some

locations have received trace amounts. Additional rainfall is not expected in the next two weeks.

The autumn-sown crop is progressing well. Harvesting should begin within a week or two in

some locations. Bulb yields and quality should be good as environmental conditions have been

ideal. 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 5 to 12

true leaves per plant with those earlier maturing cultivars producing the largest plants.

Onion Crop Growth Stage and Status Last Modified: 05/09/13

The autumn-sown crop is progressing well. Harvesting should begin within a month in some

locations. Bulb yields and quality should be good as environmental conditions have been ideal.

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 3 to 12 true

leaves per plant with those earlier maturing cultivars producing the largest plants.

Weather Impacts (temperature, rain, hail, freezing) Last Modified: 05/09/13

Temperatures have been cooler than normal for this time of year. The temperatures have been

ideal for onion growth. Temperatures are going to increase next week. It has been 2.5 months

since the last rainfall event. Precipitation is forecasted for the next few days. Much lower

allocations of surface water for the coming growing season is of concern regarding soil salt

management. Higher salt levels in pumped irrigation water is impacting some onion production

fields.

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.

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.

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.
