Antagonism between bio‐agents and potato pathogens.
Abstract
Potato is an important food crop in the world as well as in India. It is being affected by different pathogens, viz. fungi, bacteria, viruses and nematodes. These pathogens may cause significant yield losses of the crop, if proper protection measures have not been applied. Among potato pathogens, Phytophthora infestans, Alternaria solani, Rhizoctonia solani and Fusarium spp. are the major pathogens in the fungal group, whereas Ralstonia solanacearum, Pectobacterium spp. and Streptomyces spp. are in the bacterial group. For management of these pathogens, various methods, that is, chemical control, biological control, resistant varieties, cultural control and physical control, are applied. Resistant varieties are the best and cheapest method for managing the diseases. However resistant varieties are break down their resistant over the years and moreover against some pathogen absolute resistant are not available. Chemical management is the second best option for managing the diseases, due to continuous and irrational use of the chemicals; pathogens have developed resistance against certain class of fungicides/bactericides. Moreover, these chemicals also assist in environmental pollution and toxicity in the produce. Bio‐agents are naturally occurring living organisms, which are found in rhizosphere, phylloplane, etc. These bio‐agents help in not only managing the diseases but also increasing the crop yield. Therefore, the use of bio‐agents for biological management of potato crops is the focused research area worldwide.

1. Introduction
Potato originated in the hills of Andes and Bolivia in South America. It was introduced into Europe by Spaniards in the second half of the sixteenth century, from there it spreads throughout Europe and rest of the world in the mid‐seventeenth to mid‐eighteenth century. In India, it was introduced by Portuguese in the seventeenth century. Potato is the most important crop in the world. It is affected by various diseases and pests. Diseases are the major cause of concern for reducing the economic yield and affecting status of the potato growers. Major diseases of potato are late blight, early blight, black scurf, dry rot, etc. in the fungal group, whereas bacterial wilt, soft rot/blackleg of potato and common scab in the bacterial group. Sometime these diseases may cause losses up to 75%. Potato diseases can be managed by various methods, viz. chemical control, cultural control, biological control, physical and resistant varieties. Generally, chemical control is used for managing the diseases at large scale. Due to use of chemicals (fungicides/antibiotics) for longer periods for managing the disease, it was observed that pathogens have developed resistance against certain chemicals, besides also enhanced the toxicity in the environment. To avoid development of resistance in pathogens and toxicity in the environment, the use of bio‐agents/biological control is the best option. In a simple way, biological control can be defined as the partial or total inhibition or destruction of pathogen population by other microorganisms. Broader way, Baker and Cook (1974) defined this as the reduction of inoculum density or disease‐producing activities of a pathogen or parasite in its active or dormant state, by one or more organisms, accomplished naturally or through manipulation of environment, host or antagonist or by mass introduction of one or more antagonist [1]. The first experiment in biological control with antagonists was conducted by GB Sandford in Canada [2]. Different mechanisms of biological control of pathogenic fungi have been suggested, including microbial competition, antibiosis, hyperparasitism and induction of systemic acquired resistance in the host plants [3]. Bio‐agents have remarkable capacity of multiplication; thus, when applied they multiply in exponential ratio and even can overcome stress conditions by forming thick‐walled spores [4]. Recent years have witnessed the increasing popularity of biological control agents as an alternative to fungicides [5].

Naturally occurring surface active compounds derived from microorganisms are called biosurfactants. These are amphiphilic biological compounds produced extracellularly as part of the cell membrane by a variety of bacteria, yeast and fungi [33].

4. Black scurf of potato
Black scurf is an important disease of potato in the category of soil‐ and tuber‐borne diseases. Infected seeds are the main sources of infection [42]. It affects roots, stolen, stems and tubers. The disease has two phases, viz. stem canker and black scurf. Stem canker phase is the girdling on the stem with brown colour and sometime upward rolling of the leaves also observed. Black scurf phase is formation of sclerotia on the surface of the tubers. This phase is more common in the field, particularly at the stage of plant senescent.

Fusarium dry rot is an important post‐harvest disease of potato tubers. This disease is distributed worldwide and occurs wherever potatoes are grown [54].

Different bio‐agents including fungal and bacterial were reported by various researchers for management of potato diseases. Efficacy of bio‐agents is varied from lab to field conditions. It might be due to non‐synchrony environment between lab and field. Some
