Common Strategies to Control <i>Pythium</i> Disease

Abstract

Pythium species are soil-borne pathogens which can cause serious economic loss worldwide and threatening agricultural production. Traditional management methods like chemical fungicides are effective against Pythium spp. But as people pay more attention to human health and environmental issues, alternative methods that are ecofriendly and harmless to health are urgently needed. Currently, various approaches had been made including using natural extract, regulating planting conditions, using plant growthpromoting rhizobacteria and screening disease tolerance plants. Hereby, we review the recent achievements, particularly chemical and physical methods, biocontrol and host plant defense which can be used to control Pythium disease.

The Quantitative Trait Loci Mapping of Rice Plant and the Components of Its Extract Confirmed the Anti-Inflammatory and Platelet Aggregation Effects In Vitro and In Vivo

“…Moreover, the survival rate was increased by 60% in sepsis-induced model. It has also been reported that cq-9 has antimicrobial activity against Phythium graminicola [ 63 ], which causes severe damage in rice seedlings [ 64 ].…”

Pea Breeding for Resistance to Rhizospheric Pathogens

“…Control of this pythium complex is difficult due to the interwoven nature of many species. Damping-off can be controlled using integrated disease management strategies involving cultural, biocontrol and host-resistance breeding [ 39 , 143 , 144 ]. For cultural management practices, it is important to avoid poorly drained soils, maintain good soil health, good tillage, and use disease-free seeds [ 133 , 144 ].…”

“…Damping-off can be controlled using integrated disease management strategies involving cultural, biocontrol and host-resistance breeding [ 39 , 143 , 144 ]. For cultural management practices, it is important to avoid poorly drained soils, maintain good soil health, good tillage, and use disease-free seeds [ 133 , 144 ]. Biological control using rhizobium strains has been shown to offer protection against pythium damping-off in pea [ 84 ].…”

“…Apart from biocontrol agents, compost has been reported to be effective against pythium rots in vegetables and legumes. Soils with enforced organic matter content also suppress the disease manifestation [ 112 , 144 ]. Chemical treatment with appropriate fumigants, including mefenoxam and ethaboxam, can be effective against pea [ 63 ] if long-term effects are discounted.…”

Identification of Penicillic Acid as the Active Principle of Penicillium polonicum Inhibiting the Plant Pathogen Pythium aphanidermatum, and Elucidation of Its Crystal Structure

“…Being fast growing and soilborne in nature, this pathogen is very difficult to manage. [1][2][3][4][5] Banning of many effective chemical fungicides is adding to the complexity, with no viable alternative being available. We have a programme on developing effective biological control strategies for this plant pathogen, using microbial inocula.…”
