It is well established that some bacteria can suppress plant diseases through the expression of multiple mechanisms, including the direct inhibition of plant pathogens and the indirect induction of plant host resistance pathways (Kim et al., 2011). Because of this, microbes that form close associations with plants are the primary source of active ingredients in biopesticides for the control of ...

Virulence is the primary factor used for selection of entomopathogenic fungi (EPF) for development as biopesticides. To understand the genetic mechanisms underlying differences in virulence of fungal isolates on various arthropod pests, we compared the chitinase genes, chi2 and chi4, of 8 isolates of Metarhizium anisopliae. The clustering of the isolates showed various groups depending on their...

Broad spectrum chemical pest control agents have been widely regarded as ecologically unacceptable. Due to this opinion, there is the increased social pressure to reduce their use in the future and gradually replace them by biopesticides. Viruses of a few families are known to infect invertebrates, but only those belonging to the family Baculoviridae have been used for biocontrol of pests. They...

Natural resources have been traditionally used in agriculture by humans. For example, crab and shrimp shell powder has been applied to control crop disease and improve soil fertility (Ha and Huang, 2007). On the other hand, chitin is an important structural component in fungal cell walls and can be degraded by plant chitinases to eradicate fungal infection (Grover, 2012). Plant cells can recogn...

AIMS Trichoderma harzianum strains T22 and T39 are two micro-organisms used as active agents in a variety of commercial biopesticides and biofertilizers and widely applied amongst field and greenhouse crops. The production, isolation, biological and chemical characterization of the main secondary metabolites produced by these strains are investigated. METHODS AND RESULTS Of the three major co...

This investigation was aimed to study the management of bollworms using different integrated pest management strategies in cotton. Highest infestation in bolls at harvest was recorded in module-5 and lowest was recorded in module-2. Net returns were highest in module-5, which also recorded maximum cost-benefit ratio. Low net returns and cost-benefit ratio were recorded in module-3. Eventhough, ...

Abstract . Some biopolymer materials can be used as filler to increase the slow release capacity of active component. Technology modification biopesticide production processes its use sodium alginate, maltodextrin and CMC (Carboxy Methyl Celluose). The purpose this research activity was modify formulation several types concentrations biopolymers analyze characteristics in citronella oil-based b...

Till a few decades ago, chemical pesticides proved to be boon in reviving our country from the food crisis, but we soon came know that these chemicals also have side effects, which is causing great harm living being and environment. To avoid effects best substitutes are biopesticides, use of biopesticides much less as compared pesticides. There many reason for this, one main lack their resource...

This 14-page guide written by Lynn M. LeBeck and Norman C. Leppla published the UF/IFAS Entomology Nematology Department provides assistance in selecting, purchasing using commercially available natural enemies biopesticides for managing accurately diagnosed pest problems. 

Using a rodent malaria model, we found that exposure to surfaces treated with fungal entomopathogens following an infectious blood meal reduced the number of mosquitoes able to transmit malaria by a factor of about 80. Fungal infection, achieved through contact with both solid surfaces and netting for durations well within the typical post-feed resting periods, was sufficient to cause >90% mort...
