Micronutrients and Soil Microorganisms in the Suppression of Potato Common Scab

Abstract

Nature-friendly approaches for crop protection are sought after in the effort to reduce the use of agrochemicals. However, the transfer of scientific findings to agriculture practice is relatively slow because research results are sometimes contradictory or do not clearly lead to applicable approaches. Common scab of potatoes is a disease affecting potatoes worldwide, for which no definite treatment is available. That is due to many complex interactions affecting its incidence and severity. The review aims to determine options for the control of the disease using additions of micronutrients and modification of microbial communities. We propose three approaches for the improvement by (1) supplying soils with limiting nutrients, (2) supporting microbial communities with high mineral solubilization capabilities or (3) applying communities antagonistic to the pathogen. The procedures for the disease control may include fertilization with micronutrients and appropriate organic matter or inoculation with beneficial strains selected according to local environmental conditions. Further research is proposed to use metagenomics/metabolomics to identify key soil–plant–microbe interactions in comparisons of disease-suppressive and -conducive soils.

Film and Video Quality Optimization Using Attention Mechanism-Embedded Lightweight Neural Network Model

“…The skip-connection module helps solve vanishing gradient descent, reducing training time and efficiency [ 32 ]. SSCA module connects the encoder-decoder network framework and performs nonlinear transformation, extracting feature maps under a suppressed noise [ 33 ]. The SSCA is manifested in Figure 9 .…”

The influence of bio-char on Common scab disease of potatoes

“…Furthermore, the inconsistent initial increase in soil pH to eight or above by the addition of organic materials resulted in an increase in free ammonium levels that might be toxic to populations of S. scabies (Conn and Lazarovits 1999, Sagova-Mareckov , et al, 2015, Roy, et al, 2006and Kopecky et al, 2021. Soil amended-bio-char, in this study, resulted in significant decrease of potato common scab infection, similar findings is being reported elsewhere (Siddiqui et al 2008;Ghorbani et al 2008;Siddiqui et al, 2009;Siddiqui et al, 2013and Abdel-Hamid et.al., 2016 The observed decrease in bulk density (Bd) could be created by several reasons, that may co-inside with the biochar properties such as particle size, active surface area, porosity as well as properties of the soil (Toková et al, 2020).…”

Potato Microbiome: Relationship with Environmental Factors and Approaches for Microbiome Modulation

“…However, the basic mechanisms underlying the formation of the microbiome and their effects on the host plant are still poorly understood. Existing reviews related to the potato plant microbiome tend to focus on specific aspects of potato crop production: soil amendment [36], tillage practices [37], sustainable agrosystems [38], straw mulching practices [39] and disease control using micronutrients and high solubi-lization capabilities [40]. Most of the reviews we examined did not adequately address the interaction between the potato plants and microbes, nor did they explore the diversity and structural changes in the potato microbiome under the influence of biotic and abiotic factors.…”
