Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Fungus

His primary scientific interests are in Rhizobacteria, Botany, Agronomy, Inoculation and Microbiology. His biological study spans a wide range of topics, including Leaf spot, Horticulture, Solanaceae, Erwinia and Plant defense against herbivory. His studies in Botany integrate themes in fields like Bacillus pumilus and Pseudomonas.

Joseph W. Kloepper has researched Agronomy in several fields, including Agriculture, Rhizosphere, Nutrient and Microbial inoculant. He interconnects Colletotrichum orbiculare, Microorganism, Biotechnology, Pseudomonas putida and Cucurbitaceae in the investigation of issues within Inoculation. His Microbiology study combines topics in areas such as Jasmonic acid, Arabidopsis, Fusarium oxysporum and Arabidopsis thaliana.

His most cited work include:

  • Bacterial endophytes in agricultural crops (1372 citations)
  • Induced Systemic Resistance and Promotion of Plant Growth by Bacillus spp. (1168 citations)
  • Enhanced plant growth by siderophores produced by plant growth-promoting rhizobacteria (1123 citations)

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

Joseph W. Kloepper mainly investigates Rhizobacteria, Botany, Agronomy, Horticulture and Microbiology. His Rhizobacteria research is classified as research in Rhizosphere. His Botany research is multidisciplinary, incorporating elements of Bacillus pumilus, Colonization and Pseudomonas.

The study incorporates disciplines such as Nutrient and Root-knot nematode in addition to Agronomy. His Microbiology study integrates concerns from other disciplines, such as Salicylic acid, Jasmonic acid and Pseudomonadaceae. His study in Inoculation is interdisciplinary in nature, drawing from both Bacillus amyloliquefaciens, Fusarium wilt and Pseudomonas putida.

He most often published in these fields:

  • Rhizobacteria (52.54%)
  • Botany (34.75%)
  • Agronomy (30.51%)

What were the highlights of his more recent work (between 2016-2021)?

  • Rhizobacteria (52.54%)
  • Agronomy (30.51%)
  • Biological pest control (13.56%)

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

His scientific interests lie mostly in Rhizobacteria, Agronomy, Biological pest control, Rhizosphere and Horticulture. His Rhizobacteria research incorporates themes from Plant growth, Rhizoctonia solani, Botany, Seed treatment and Microbial inoculant. His research brings together the fields of Beneficial bacteria and Botany.

His work deals with themes such as Biomass, Bacillus sp, Inoculation and Poultry litter, which intersect with Agronomy. His Rhizosphere study incorporates themes from Bacillus amyloliquefaciens, Ribosomal RNA, Siderophore and Colonization. In his study, which falls under the umbrella issue of Horticulture, Sowing is strongly linked to Meloidogyne incognita.

Between 2016 and 2021, his most popular works were:

  • Selection and Assessment of Plant Growth-Promoting Rhizobacteria for Biological Control of Multiple Plant Diseases. (62 citations)
  • Mixtures of Plant-Growth-Promoting Rhizobacteria Enhance Biological Control of Multiple Plant Diseases and Plant-Growth Promotion in the Presence of Pathogens. (48 citations)
  • The Interactions of Rhizodeposits with Plant Growth-Promoting Rhizobacteria in the Rhizosphere: A Review (40 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Gene
  • Fungus

The scientist’s investigation covers issues in Rhizobacteria, Biological pest control, Agronomy, Bacillus altitudinis and Plant growth. His Rhizobacteria research incorporates themes from Colonization and Horticulture. He has included themes like Beneficial bacteria, Endospore, Seed treatment and Botany in his Colonization study.

His work deals with themes such as Rhizoctonia solani and Pseudomonas syringae, which intersect with Biological pest control. The Agronomy study combines topics in areas such as Nutrient and Microbial inoculant. His studies in Plant growth integrate themes in fields like Fresh weight, Agriculture and Biotechnology.
