Insect 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 کاملInsect Growth Regulators for Insect Pest Control*
Insecticides with growth regulating properties (IGR) may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Some insects exposed to such compounds may die due to abnormal regulation of hormone-mediated cell or organ development. Other insects may die either from a prolonged exposure at the developmental st...
متن کاملNutsedge (cyperus Spp) Control in Alfalfa
The competitive advantage of purple and yellow nutsedge in low desert alfalfa production areas of Southern California and Arizona is due to a combination of factors. These include frequent harvest and irrigation, high incident solar radiation, high summer temperatures that are supraoptimal for alfalfa growth, and the presence of C4 photosynthesis and vegetative reproduction (e.g., tubers) in nu...
متن کامل1996 Control and Decision Conference
Lagrangian control systems that are diierentially at with at outputs that only depend on connguration variables are said to be connguration at. We provide a complete characterisation of connguration atness for systems with n degrees of freedom and n ? 1 controls whose range of control forces only depends on conng-uration and whose Lagrangian has the form of kinetic energy minus potential. The m...

The creation in October 1964 of this Division, which includes the Insect Pest Control Subprogramme, marked the beginning of what is certainly a unique and arguably the best example of inter-agency cooperation within the whole UN family. The goal was to join the talents and...
