Psyllid captures remain low; no new positives

Potato    All Locations

potato psyllid

Posted on: August 10, 2023 by Erik Wenninger

This week we received traps from 50 of the 55 fields that we are monitoring. We captured a total of 30 psyllids across 12 fields. Seven of the fields were in Canyon County, the remaining 5 fields were in Payette, Owyhee, Elmore, and Twin Falls counties.

Total psyllid captures were similar to last week, and we continue to see quite low numbers this season. 

All of the psyllids captured last week were negative for Lso, the bacterium associated with zebra chip disease (ZC). We still urge growers to have their IPM programs in place given the prevalence of Lso earlier in the season.

2022 Potato psyllid monitoring program underway in Idaho

Potato    All Locations

potato psyllid

Posted on: July 7, 2022 by Erik Wenninger

The University of Idaho and our crop consultant collaborators across the state are once again monitoring for potato psyllids, zebra chip disease (ZC), and liberibacter (Lso), the bacterium associated with ZC. The monitoring program covers commercial potato fields throughout southern Idaho and is funded in part by the Idaho Potato Commission and generous in-kind contributions by our cooperators. 

Our official monitoring season began with wide deployment of traps last week and will continue for 10 to 12 weeks. We have 72 fields across the state this year, using 4 sticky traps per field at all sites. 

This week we had traps deployed in 64 fields, though we are still waiting for traps to come in from three fields. We found a total of 12 psyllids across 7 (11%) of the fields for which we have data. We have been monitoring three fields at the Kimberly Research & Extension Center since mid-May, and, interestingly, this week is the first that we have found potato psyllids. In previous years we nearly always captured psyllids here before the end of May. 

Psyllids were captured in the following counties: Canyon (3 fields), Owyhee (1 field), Twin Falls (2 fields), and Minidoka (1 field).

We expect to have results on Lso incidence next week in addition to “heat maps” and additional details.

2022 Turfgrass Mowing Height & Watering

General Landscape and Garden    Treasure Valley, Treasure Valley - Idaho, Northern Idaho

Turfgrass Mowing Height & Watering

Posted on: July 6, 2022 by Ruth Givens

MOWING

The weather is warming and now is the time to check the mowing height at which your turfgrass is cut. Increasing the length of grass blade encourages a deeper root growth and provides more shade cover of the soil surface reducing water evaporation.

For summer mowing height Kentucky bluegrass and fine fescue are recommended to be maintained at 3 inches, perennial ryegrass at 2 inches, and tall fescue at 4 inches. Ensure that the mower blade is sharp and follow the one-third rule; remove no more than one-third of the leaf growth each mowing.

Grass clipping which are left on the lawn by mulching decompose quickly, feed soil organisms, recycle plant nutrients, and increase organic matter in the soil.

WATERING

The goal of irrigation is to keep the lawn healthy when rainfall is not dependable. The key is to moisten the top 12 inches of the root zone. Watering deeply (10 to 12 inches) but infrequently produces healthy turf. Practicing deep watering reduces weed populations, benefits landscape trees and shrubs, increases water use efficiency, and forces an exchange of soil atmosphere with each irrigation. Early morning is the best time to water.

Determining how deep irrigation water goes can be done by using a soil probe or shovel to check soil moisture the day after irrigation. At 10 to 12 inches deep the soil should feel slightly damp. If the soil feels dry at the 10- to 12-inch depth increase the duration of water application to fill the root zone. As weather conditions change adjust the frequency of irrigation to maintain plant available water in the root zone.

Identifying or knowing soil type will help to determine the frequency of water application, rate of water infiltration, and the soils water holding capacity. For example, heavy clay soils have a greater water holding capacity, but have a slower infiltration rate (speed at which water enters the soil). These soils can be watered less frequently (once a week or less) and may need multiple application of water on day of watering to allow water to move into the soil.  Sandy soils have less water holding capacity and a greater infiltration rate. These soils need to be watered more frequently to maintain comparable turf.

For a more calculated approach to water application reference the publication links below.

Powdery Mildew and Cercospora in Sugarbeets

Sugarbeets    All Locations

powdery mildew and cercospora

Posted on: June 30, 2022 by Jerry Neufeld

Powdery mildew and Cercospora leaf spot have been found by Amalgamated Sugar Company Crop Consultants in sugarbeet fields in the western Treasure Valley.  There are several fungicides available for use to treat these diseases. Depending on the disease pressure and chemistry used, applications with different chemistries should be repeated every 14-21 days. Please be advised that strobilurins could show reduced efficacy due to fungicide resistance in powdery mildew. Always tankmix with at least 5 lbs of sulfur for resistance management purposes when treating against powdery mildew. For the same reason, use a copper product as tank mix partner when treating against Cercospora. DO NOT MIX COPPER AND GLYPHOSATE. Contact your Crop Consultant from The Amalgamated Sugar Company LLC if you have any questions.

2022 Squash Bug (Anasa tristis)

General Landscape and Garden    Treasure Valley

Squash bug (Anasa tristis)

Posted on: June 30, 2022 by Maria Held



2022 Squash Bug



Squash
bugs eggs have been reported in Canyon County by the Canyon County Master
Gardener Integrated Pest Management (IPM) Team in Caldwell. Adults have been spotted by a Master Gardener in
Meridian.  It is time to check the
underside of cucurbit (pumpkins and squash are the most attractive) leaves for
the bronze-colored egg clusters. In addition, monitor plants for nymphs, adults
and plants wilting. 



Management:



Wooden
boards, shingles, or heavy cardboard can be placed on the ground next to the
host plant. Squash bugs tend to move under the board/object at night. In the
morning, turn the object over and destroy the pest.



Hand-pick
and destroy adults, nymphs, or egg clusters. Other options include rolled duct
tape around fingers to pull off egg clusters, cutting off the egg part of the
leaf or applying petroleum jelly directly to the eggs. Increased success is
achieved when started early in the season and done every 2 to 3 days to keep
numbers low.



Cultural
methods include sanitation, plating squash varieties that are more tolerant of
squash bug feeding, crop rotation, and time of planting. 



Additional
control methods can be found in the linked publications.

2022 Peachtree Borer

General Landscape and Garden    Treasure Valley, Treasure Valley - Idaho, Northern Idaho

Peachtree Borer

Posted on: June 29, 2022 by Ruth Givens

Peachtree bores are predicted to emerge between July 2 and July 5. This pest is a concern for stone fruits: Peach, nectarine, apricot, cherry, and plum. Key symptoms of peachtree borer infestation is the presence of sawdust and frass mixed with the gummy substance near the base of the trunk. Prevention is the best method of control.

Larvae injure the fruit tree primarily by burrowing into the tree trunks just at or below the soil line but may enter trunk up to 12” above the soil line. Larvae feed in the cambium beneath the bark girdling the tree.

Chemical Control, Home Use: For orchards less than 1 acre, or for home yard trees, preventative trunk sprays are the primary control. Apply the first application immediately after first trap catch and repeat application based on product label guidelines. Follow the required pre-harvest interval (time between last application and allowed harvest of fruit) of insecticide product. Apply insecticide as a bark drench at a rate of ½ to 1 gallon of spray mix per tree. Thoroughly cover the lower 12 inches of trunk and soak the ground at the base of tree. Do not allow the sprays to contact fruit. For chemical option review the PNW handbook link below.

Chemical Control, Commercial: Reference the PNW handbook link below to see spring and summer application recommendations.

Cultural Control: Larvae inside the trunks can be killed by inserting a wire into entry holes. Kill larvae in the late summer and fall before they spend the winter and inflict their most extensive feeding damage the following spring. Keep base of tree free of vegetation – heat and dryness reduce the survival of eggs and larvae.

The following links have information about the life cycle of peachtree borer and control methods.

2022 Peach Twig Borer

General Landscape and Garden    Treasure Valley, Treasure Valley - Idaho, Northern Idaho

Peach Twig Borer

Posted on: June 22, 2022 by Ruth Givens

It is time for management of the peach twig borer, based on degree days. This pest is a concern for those growing peach, nectarine, apricot, plum and prune. Adult moths are 0.3 – 0.5 inches long, with light and dark gray mottled wings. Scales on the front of head cause the head to appear pointed. The larva is a caterpillar, about 0.5 inch long, with a dark brown head and distinctive, alternating light and dark bands on the body. 

Larvae injure fruit trees by feeding on the buds and twigs early in the season, then the larvae bore into the shoots, causing a characteristic "flagging" or wilting of the new growth. Later generations of larvae feed within shoots or even on the fruit itself. Flagging of twigs indicates an infestation.

For chemical control management options review the PNW Handbook link below to select a control option appropriate for operation. Apply according to label directions.

For cultural controls prune out shoot strikes in the late spring and early summer as soon as they are detected to prevent these larvae from completing development and contributing to summer generations of the pest. If old shoot strikes are observed during pruning in late winter to early spring, plan to apply early season controls. Old strikes hold onto the dead leaves and appear as “flagged” terminals.
