Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Horticulture
  • Ecology

The scientist’s investigation covers issues in Agronomy, Horticulture, Verticillium dahliae, Botany and Crop. His study explores the link between Agronomy and topics such as Inoculation that cross with problems in Summer fallow and Field experiment. His Verticillium dahliae study integrates concerns from other disciplines, such as Chloropicrin, Fungi imperfecti, Verticillium wilt and Verticillium.

Steven T. Koike has included themes like Bacterial blight, Host and Sudden death in his Botany study. His Crop study combines topics in areas such as Broccoli raab, Asparagus, Apiaceae and Cultural control. His research integrates issues of Potting soil and Spinach in his study of Sowing.

His most cited work include:

  • Phytophthora ramorum as the Cause of Extensive Mortality of Quercus spp. and Lithocarpus densiflorus in California. (508 citations)
  • Winter cover crops in a vegetable cropping system: Impacts on nitrate leaching, soil water, crop yield, pests and management costs (178 citations)
  • Effects of Crop Rotation and Irrigation on Verticillium dahliae Microsclerotia in Soil and Wilt in Cauliflower. (101 citations)

What are the main themes of his work throughout his whole career to date?

Steven T. Koike mostly deals with Botany, Horticulture, Agronomy, Inoculation and Conidium. His study looks at the relationship between Botany and fields such as Pseudomonas syringae, as well as how they intersect with chemical problems. His Horticulture research is multidisciplinary, incorporating elements of Pathogenicity and Spinach.

In his study, which falls under the umbrella issue of Spinach, Pathogen and Oomycete is strongly linked to Downy mildew. Crop, Verticillium dahliae, Verticillium wilt, Cultural control and Cover crop are the subjects of his Agronomy studies. The Conidium study combines topics in areas such as Potato dextrose agar and Spore.

He most often published in these fields:

  • Botany (50.61%)
  • Horticulture (39.26%)
  • Agronomy (27.91%)

What were the highlights of his more recent work (between 2012-2021)?

  • Horticulture (39.26%)
  • Botany (50.61%)
  • Agronomy (27.91%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Horticulture, Botany, Agronomy, Spinach and Cultivar. In his work, Rhizoctonia solani, Sclerotinia, Sclerotinia minor and Fusarium avenaceum is strongly intertwined with Crown, which is a subfield of Horticulture. His Botany study combines topics from a wide range of disciplines, such as Pathogenicity, Pseudomonas syringae and Ribosomal DNA.

Steven T. Koike combines subjects such as Soil water and Fusarium oxysporum with his study of Agronomy. Steven T. Koike works mostly in the field of Spinach, limiting it down to topics relating to Downy mildew and, in certain cases, Oomycete, Pathogen and Oospore. Within one scientific family, Steven T. Koike focuses on topics pertaining to Plant disease resistance under Cultivar, and may sometimes address concerns connected to Fusarium wilt and Germplasm.

Between 2012 and 2021, his most popular works were:

  • Management of Fusarium wilt of strawberry (34 citations)
  • Anaerobic soil disinfestation is an alternative to soil fumigation for control of some soilborne pathogens in strawberry production (32 citations)
  • Practical Benefits of Knowing the Enemy: Modern Molecular Tools for Diagnosing the Etiology of Bacterial Diseases and Understanding the Taxonomy and Diversity of Plant-Pathogenic Bacteria (32 citations)
