Evaluation of Experimental Populations and Glandular-Haired Varieties of Alfalfa for Alfalfa Blotch Leafminer (Diptera: Agromyzidae) Feeding Injury [PDF]

open access: yes, 2018
Following the spread of the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae), into Minnesota and Wisconsin U.S.A. during 1994-1997, three field trials were conducted in Minnesota to assess the potential for leafminer ...

Effect of Alfalfa Meal, Alfalfa Leaves, Alfalfa Stems and Fresh Alfalfa on Chick Growth

open access: yesPoultry Science, 1951
Abstract Studies by various investigators, Cooney et al. (1948); Draper et al. (1948); Lepkovsky et al. (1949); and Kodras et al. (1951), have shown that there is a relation between the depression of chick growth and the level of alfalfa meal in the rations. Data obtained by Cooney et al. with chicks fed rations containing alfalfa meal and equivalent

Fungal Pathogens Infecting Soybean Aphid and Aphids on Other Crops Grown in Soybean Production Areas of Michigan [PDF]

open access: yes, 2018
Seasonal prevalence of fungal pathogens infecting soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), was assessed from 2004 to 2006 in two Michigan soybean production areas. In 2005 and 2006 field-collected soybean aphids were incubated, and

Over-Expression of Arabidopsis EDT1 Gene Confers Drought Tolerance in Alfalfa (Medicago sativa L.)

open access: yesFrontiers in Plant Science, 2017
Alfalfa (Medicago sativa L.) is an important legume forage crop with great economic value. However, as the growth of alfalfa is seriously affected by an inadequate supply of water, drought is probably the major abiotic environmental factor that most ...

Abundance of Coccinellids and Their Potential Prey in Field-Crop and Grass Habitats in Eastern South Dakota [PDF]

open access: yes, 2018
A rich fauna of coccinellids occurs in eastern South Dakota, but the abundance of some species has declined in association with the establishment of an exotic lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), in the mid-1980s.

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

open access: yesAdvanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.
