Endophytes are symbiotic microorganisms that colonize plant tissues and benefit plants in multiple ways including induced systemic resistance to biotic and abiotic stresses. Endophytes can be sustainable alternatives to chemical nematicides and enhance plant health in a variety of cropping and natural environments. Several in vitro and in vivo stud...
Chapter
Beneficial microbes used for the control of crop pests have one or more modes of action against their target arthropods, nematodes, pathogens, or weeds. Metabolites, enzymes, volatile compounds, and other bioactive materials help them to antagonize and suppress target pests. The pesticidal activity of several microbial metabolites has been extensiv...

As the demand for sustainably produced food is increasing, the use of biopesticides has also been increasing in the recent years. While biopesticides based on entomopathogens have been successfully employed for pest management around the world for decades, there are still some concerns about their efficacy relative to chemical pesticides, limiting...

Strawberry is a high value and labor-intensive specialty crop in California. The three major fruit production areas on the Central Coast complement each other in producing fruits almost throughout the year. Forecasting strawberry yield with some lead time can help growers plan for required and often limited human resources and aid in making strateg...

California strawberries have two major arthropod pests—the twospotted spider mite, Tetranychus urticae and the western tarnished plant bug, Lygus hesperus, which result in significant losses to the yield and quality of marketable berries. Other important insect pests that are frequently seen in strawberry include the greenhouse whitefly, Trialeurod...

The biopesticide industry in India is undergoing rapid change, reflecting increased global trade in agricultural commodities, a changing regulatory environment and evolving consumer preferences. Currently biopesticides comprise ≈ 5% of the Indian pesticide market, with at least 15 microbial species and 970 microbial formulations registered through...

The western tarnished plant bug (or lygus bug) and different species of spider mites are major arthropod pests in California strawberries. While predatory mite releases are very popular for controlling spider mites in both organic and conventional fields, a significant amount of chemical pesticides are used for arthropod pest management in conventi...
Article
Biological control programs with arthropods have been in practice in Iran since the 1930s. However, development and registration of microbial biopesticides is much more recent. Currently, about 15 biopesticide products are registered or pending registration for commercial use on various crops. Products based on Bacillus thuringiensis subsp. kurstak...
Article
Microbial pesticides based on bacteria, fungi and viruses or their bioactive compounds have long been developed as alternatives for synthetic pesticides to control invertebrate pests. However, concern for environmental and human health from excessive reliance on chemical pesticides, changes in residue standards, and increased demand for organically...

Eggs, nymphs, and adult silverleaf whitefly on zucchini. Photo by Surendra Dara A study was conducted in the summer of 2017 to evaluate the efficacy of various chemical, botanical, and microbial pesticides against arthropod pests on zucchini. Zucchini plants initially had a high aphid infestation, but populations gradually declined due to natural c...
Chapter
Microbial control falls within the realm of biological control, where biocontrol agents such as parasitoids, predators, and microbial control agents (MCAs) are either released or conserved for pest management. Classical microbial control (also referred to as the introduction/establishment approach) typically involves exploration of invertebrate pat...

Alternatives to soil fumigation are needed for soil-borne disease control. Our goal was to test anaerobic soil disinfestation (ASD) as an alternative to soil fumigation for control of critical soil-borne pathogens in California strawberry production. Controlled environment experiments were conducted at 25°C and 15°C testing different materials as c...
