SCOUT FOR DIAMONDBACK MOTH AND BERTHA ARMYWORM IN CANOLA

The diamondback moth migrates into ND and usually arrives in late May or early June in North Dakota. The complete life cycle takes about 32 days from egg to adult. There are several generations during a single growing season, so all different life stages (eggs, larvae, pupae, adults) can be found in the field at the same time.

The adult is small, about ½-inch long, drab brown in color and, at rest, the forewings of the male moth form three diamonds – hence the name diamondback moth. Females lay up to 160 eggs during the night. Eggs hatch in five to six days into pale yellowish-green caterpillars with a forked posterior end. The newly emerged larvae burrow into the leaf and mine the leaf for several days to a week. Then, the larvae exit the leaf and feed externally for another 7 to 14 days. When disturbed, the larvae thrash backwards violently and often drop from the plant on a strand of silk. The larvae pupate for 5 to 15 days in a white net-like cocoon attached to the leaves, stems or pods.

Larvae feed on the leaves, buds, flowers, seed pods, the green outer layer of the stems, and occasionally, the developing seeds. As leaves wilt and drop in late July to early August, larvae will feed on the stem, pods, and developing seeds. Damaged pods will not fill completely and may shatter. Severely damaged pods appear whitish in contrast to the normal yellowing and browning of ripening undamaged pods.

Scout fields for diamondback moth larvae by beating plants to dislodge the larvae into white buckets. After beating plants, count larvae in the bucket or dangling from plants on a silk thread. Again, check several locations per field. For the early flowering stage, insecticide applications may be justified at larval densities of 10 to 15 larvae per square foot. The action threshold for canola at the pod stage is an average of 20 larvae per square foot.

The best pest management strategies to avoid yield losses from diamondback moth include early field scouting for larvae, and judicious use of insecticides only when fields are above thresholds. For more information, consult the NDSU Extension publication on Diamondback moth in Canola: Biology and Integrated Pest Management E1346 (revised).

Bertha armyworm: The adult moth is about 1½ inches long and mainly grayish-black with a silvery-whitish kidney-shaped spot and with a silvery-whitish fringe on each forewing. Moths emerge from the overwintering pupae in mid-late June and emergence continues through early August. These night fliers are particularly attracted to blooming canola fields for their nectar and egg laying sites. Eggs are laid on the lower side of leaves in clusters of 50-500 eggs in a honeycomb pattern and hatch in about one week. The emerging larvae (1/10th of an inch) are usually green in color. Mature larvae are about 1½ inch long and vary in color from green to brown to velvety black. Larvae often hide underneath leaf litter and clumps of soil during the day, which makes them difficult to see. Larvae develop for six weeks and then drop to the ground in mid to late August to pupate. There is only one generation per year.

As the canola plant drops its leaves, the mature larvae (>½ inch) begin to feed directly on the pods which causes economic yield losses and premature shattering. Feeding injury by the mature larvae also accounts for 80 to 90 percent of the plant material consumed during a larvae’s life. Mature larvae will even continue to feed on pods in the swath. Fortunately, populations are kept low during most years due to natural environmental factors like harsh winters and the presence of biological control agents (diseases and parasites).

Thresholds would be 18 to 22 larvae per square yard, if leaf feeding is the extent of the damage observed. The key to controlling bertha armyworm is:

 Early detection of young larvae about ½ inch long in canola fields by regular scouting.

 Determining if fields are above economic thresholds for larvae.

 Fields above the economic threshold level should be sprayed once the hatch is complete and just before larvae move to the pods. Apply a well-timed insecticide in late evening when larvae are actively feeding.

 Use high volumes of water for good coverage of the dense canola canopy.

For more information, consult the NDSU Extension publication on Bertha armyworm in Canola: Biology and Integrated Pest Management E1347 (revised).

Please see the NDSU Extension E1143 2019 ND Field Crop Insect Management Guide for insecticides registered in canola. Please remember that blooming canola is attractive to bees, so insecticides should be applied in the late evening (preferred by honey bee keepers) or early morning to minimize negative effects of an insecticide on bees.

BLISTER BEETLES IN FIELD CROPS

Ash gray blister beetles, Epicauta fabricii, have been reported in canola, soybean and alfalfa fields in central, northwest and north central areas of ND. Adult blister beetles can be an occasional pest causing defoliation to the leaves and clipping flowers or pods. In canola, they are attracted to blooming canola fields for its nectar and pollen, but they also devour leaves, flowers and pods. Blister beetles are a major problem in alfalfa / hay fields or in bales, since they produce a toxic chemical (cantharidin), which is toxic to livestock, especially horses. Larvae of Epicauta species actively prey on grasshopper egg pods.
Blister beetles are mobile and gregarious, and often congregate in certain spots in a field (edges). In some instances, blister beetles only feed for a short period and then migrate to other fields. Alfalfa and forage are preferred hosts of blister beetles and they often move into canola or other field crops after the alfalfa is cut. If treatment is necessary to avoid yield loss, producers can ‘spot treat’ with a foliar insecticide. Please avoid spraying flowering crops for bee/pollinator safety.

FLEA BEETLES HIGH IN CANOLA

At the start of spring, the cool, wet weather delayed emergence of flea beetles and the early to mid-May-seeded canola. Now, the hot weather has pushed flea beetles to emerge in large numbers just as the canola is popping. After the seed sits in the ground for 21+ days with little plant growth, the effectiveness and residue of the neonicotinoid seed treatment is significantly reduced. This week some growers are spraying a foliar ‘rescue’ insecticide treatment on top of the insecticide seed treatment to manage the ‘feeding frenzy’ of flea beetles. In some case, three foliar applications were applied to manage the different emergence waves of flea beetles. Hot spots are in the major canola producing areas of ND including North Central (Bottineau Co.), Northeast (Cavalier Co.) and Southwest.
Fields should be scouted daily to identify economic injury or poor performance of insecticide seed treatments. Look for pitting and defoliation on cotyledons and true leaves when scouting. Flea beetle often concentrate on edges of fields in cool wet weather. Walk a W pattern and scout five sites per field. Estimate defoliation on 10 plants per site. Calculate the average defoliation level among the plants inspected.
For foliar insecticide applications, the action threshold is when an average of 20-25% defoliation is found on the cotyledons and/or first true leaves, and beetles are actively feeding in the field.
Foliar treatments must be made quickly. The weakness of foliar control strategies is the inability to cover large number of acres quickly when feeding pressure is high, and residual protection by the insecticides is short (only 5-10 days depending on weather and rate of insecticide), allowing for reinfestation to occur.
Pyrethroid insecticides (a.i. bifenthrin, deltamethrin, gamma-cyhalothrin, zeta-cypermethrin) provide good control of flea beetles and a 7- 10 day residual at the high-labeled rate. If it is hot (above 85⁰F), pyrethroid insecticides break down faster and are not as efficacious at controlling insect pests. So, insecticide application may need to be applied early in the morning or in the evening when daytime temperatures are hot. Insecticides registered for flea beetle management in canola are listed in the 2019 North Dakota Field Crop Insect Management Guide E1143.

Canola Growers To Be Included in New Ag Trade Package

The NCGA just received confirmation that canola will be included in the recently announced Ag trade Package from USDA. Other crops left out in last year’s payments will also be included.  Payments will be based on a single county rate multiplied by a farm’s total plantings to those crops in aggregate in 2019. Per acre payments are not dependent on which crops are planted in 2019, and therefore will not distort planting decisions.  Total payment-eligible plantings cannot exceed total 2018 plantings.

Payments will be made in up to three tranches, with the second and third tranches evaluated as market conditions and trade opportunities dictate. The first tranche will begin in late July/early August as soon as practical after Farm Service Agency crop reporting is completed by July 15th. If conditions warrant, the second and third tranches will be made in November and early January.

Further details on the payments will be provided this afternoon.

NCGA Request to USDA

May 14, 2019

Dear Secretary Perdue:

The Northern Canola Growers Association wishes to express its concern that canola be included as an eligible commodity under the recently announced aid package for farmers.  Canola growers have suffered tremendous market losses as a direct result of the trade dispute with China and canola oil has now been slapped with a retaliatory tariff into China.  These market losses are negatively impacting canola growers and influencing planting decisions.

The attached chart shows how canola prices have dropped right along with soybeans.  In fact, canola prices have dropped even harder than soybeans recently due to the ban on canola imports from Canada into China due to the arrest of the Huawei executive.  This will result in ending stocks of canola nearly doubling this crop season, further dampening prices.

In North Dakota, which produced over 80 percent of the U.S. canola crop, the cash price at the ADM Velva crushing plant for canola has dropped from $17.78 on June 15, 2018 to $15.00 as of today, a decline of 16 percent. 

Using the 2018 national average yield of 1,861 pounds/acre, U.S. canola producers are facing an average loss of $51.74 per acre, equal to almost $103 million in lost revenue when applied to the 1.99 million acres of canola planted in 2018.

We therefore request that canola be included in the announced aid package as an eligible commodity so that canola growers can recoup a portion of the lost revenue as a result of the ongoing trade dispute with China.

Thank you for your consideration of our request.

Regards,

Barry Coleman
