Pollinators and Pesticides: What you need to Know (General)
Description: In the spirit of National Pollinator Week, June 19 – 25, producers, bee keepers and pesticide applicators are reminded of best management practices to minimize negative impacts to pollinators. The value of insect pollinated crops in the US ranges from $18 to $27 billion annually. Pollinator numbers have been decreasing worldwide for many years. This article discusses pollinators, specifically bees, and steps to reduce the risk of exposing bees to pesticides.

Wheat head armyworm damage predicted in Golden Triangle areas (General)
Description: Wheat head army worm has been a minor pest but in the recent years it has sporadically became an important pest of corn and wheat grown in Northcentral Montana by causing significant kernel damage. Alarm over this pest was elevated in 2014 with the incidence of increased percentages of insect-damaged kernels (IDK) in wheat harvested in the Golden Triangle area of Montana. The pheromone traps installed in the Golden Triangle areas during May 2017 indicated that traps caught in the rage of 40-70 moths/trap/week. This indicates the moths will lay eggs and eventually larvae will emerge and cause damage to the crops. For wheat head armyworm biology, damage potential, monitoring and management options, please refer to the attached alert and supporting documents.

Late-season nitrogen to boost grain protein (General)
Description: With relatively high wheat grain protein discounts, some farmers and their advisers are likely pondering whether to apply late-season nitrogen or not, especially in areas fortunate enough to receive decent rain this year. This alert gives some ideas on how to make that decision.

Diagnosing Herbicide Carryover in Pulse Crops (Pesticides)
Description: We have seen a sharp increase in the number of chickpea, lentil, and pea samples submitted to the Schutter Lab with symptoms consistent with herbicide carryover. These symptoms include malformation, stunting, and/or chlorosis. After reviewing herbicide records we find that many of these cases are likely attributed to an application of a soil residual herbicide in past small grain rotations. If you are sending a pulse crop sample that you suspect may be showing these types of symptoms, please include herbicide records for the past two to three years. See the attached alert document for more information.

Flea beetles and diamondback moth incidence reported on mustard (General)
Description: The crucifer flea beetle and diamondback moth have been reported on mustard in the Golden Triangle Areas of Montana (Collins, Knees, Dutton, Brady and Conrad). Both of these are pests on Brassica oilseed crops. Although larvae and adult flea beetles cause damage to the crop, adult beetles causes significant damage and yield losses, if not controlled. Larvae of diamondback moth feed on the leaves and bores into pods and eaten up the developing pods completely. For pest biology, ecology, thresholds, chemical control and other management option, please refer to attached alert documents.

High level of cereal leaf beetle incidence in Choteau, MT (Cropland Insects)
Description: High incidence of cereal leaf beetle was noticed at several locations in Choteau County. Traditionally this pest has been considered as an economic pest of spring seed cereal crops such as in wheat, barley and oats since 1999. Please refer the MontGuide and other attached documents to know about the cereal leaf beetle biology, ecology, thresholds and management guidelines.

Cutworm incidence and damage on peas (Cropland Insects)
Description: Heavy cutworm damage was noticed on peas at certain locations in the Sunburst and other Golden Triangle areas of Montana. Cutworms are the larvae (caterpillars) of numerous species of night-flying moths in the family Noctuidae, which are usually active for feeding during the night. The larvae are called cutworms because they cut down young plants when feeding on stems at or below the soil surface. Cutworm damage occurs on early in the season when plant seedlings are small and have tender tissue. On a regular basis monitor your fields, particularly during late afternoon and evening when cutworms are active, so you can notice their movement when they are initial present. Refer the MontGuide to know about biology, damage, monitoring and decision-making guidelines, http://store.msuextension.org/publications/agandnaturalresources/mt200005ag.pdf For chemical control, refer High Plains IPM Guide, https://wiki.bugwood.org/HPIPM:Cutworms_DB Cutworm
