Integrated pest management in forage alfalfa
Alfalfa, Medicago sativa L., is among the most prized of forages, and is grown worldwide as a feed for all classes of livestock. It is one of man's oldest crops, and its cultivation probably predates recorded history. In addition to its versatility as a feed, alfalfa is well known for its ability to improve soil structure and, as a legume, is an effective source of biological nitrogen. As a per...
متن کاملDeep sequencing of the microRNA expression in fall dormant and non-dormant alfalfa
MicroRNAs (miRNAs) play a critical role in post-transcriptional gene regulation that down-regulates target genes by mRNA degradation or translational repression. Evidence is increasing for their crucial roles during plant development. Identification of miRNAs at the global genome-level by high-throughput sequencing is essential to functionally characterize miRNAs in plants. Alfalfa (Medicago sa...
متن کاملRoot Physiology of Less Fall Dormant, Winter Hardy Alfalfa Selections
in nondormant, nonhardy cultivars when compared with fall dormant plants (Volenec, 1985; Boyce and Volenec, The physiological mechanisms causing fall dormancy (FD)-induced 1992; Castonguay et al., 1995; Cunningham and Volenec, differences in alfalfa (Medicago sativa L.) shoot growth in autumn and winter hardiness are not understood. The objective of this research 1998). Therefore, accumulation ...
متن کاملInsect Pest Management Issues in Alfalfa--challenges and Questions
Integrated pest management in alfalfa continues to be challenged by changes in the pests, alfalfa production system, environmental conditions, and other undetermined factors. Many of the underlying principles of integrated pest management (IPM) were developed from research conducted in the alfalfa system in the 1960-80’s. However, as indicated by challenges in controlling alfalfa weevil larvae ...
متن کاملDiatomaceous Earth for Pest Control
Least toxic physical and chemical solutions are often part of an IPM program. Various forms of amorphous silica are commonly used as part of this strategy. Diatomaceous earth and silica gel are used in various physical formulations with or without added pesticide. The type of silica and the formulation depend on the target pest. In this issue advantages and disadvantages of diatomaceous earth a...
