The strobilurin fungicides

Strobilurins are one among the foremost important classes of agricultural fungicide. Their invention was inspired by a gaggle of fungicidally active natural products. The outstanding benefits they deliver are currently being utilised during a wide selection of crops throughout the planet . First launched in 1996, the strobilurins now include the world’s biggest selling fungicide, azoxystrobin. By 2002 there’ll be six strobilurin active ingredients commercially available for agricultural use. This review describes intimately the properties of those active ingredients – their synthesis, biochemical mode of action, biokinetics, fungicidal activity, yield and quality benefits, resistance risk and human and environmental safety. It also describes the clear technical differences that exist between these active ingredients, particularly within the areas of fungicidal activity and biokinetics. [1]

Fungicides in plant disease control.

This book, aimed toward students, teachers, researchers and extension workers in India, provides information on the character , mode of action and use of fungicides in successful crop disease control. Six fungicide groups are considered: sulfur, copper, mercury, quinone and dicarboximide fungicides and captan, folpet and captafol. Systemic fungicides are considered during a separate chapter and therefore the management of fungicide tolerance is additionally discussed. Information on the chemicals utilized in disease control, sources of chemicals, soil disinfesting chemicals and methods of application, standardized spray nomenclature and prescriptions for crop disease control is appended.

Fungicides in crop protection.

This book comprises 8 chapters: introduction; the fungicides market; fungicide discovery; fungicide performance; fungicide resistance; natural products and therefore the biological control of crop disease; legislation; and summary: trends in fungicide use. the topic of fungicide use is approached from an economic standpoint. The continuing diversification of the industry is described during which the utilization of natural products and therefore the ir derivatives with biological control systems and the use of biotechnology in crop protection are highlighted. The book is aimed toward undergraduates and graduates in plant pathology, advisors, extension workers and new recruits to the agrochemical industry. [3]

Resistance Mechanisms and Molecular Docking Studies of Four Novel QoI Fungicides in Peronophythora litchii

Peronophythora litchii is that the cause of litchi downy blight. Enestroburin, SYP-1620, SYP-2815 and ZJ0712 are four novel QoI fungicides developed by China. Eight mutants of P. litchii immune to these QoI fungicides and azoxystrobin (as a known QoI fungicide) were obtained in our preliminary work. during this study, the complete length of the cytochrome b gene in P. litchii, which features a full length of 382 amino acids, was cloned from both sensitive isolates and resistant mutants and single-site mutations G142A, G142S, Y131C, or F128S were found in resistant mutants.

Bioefficacy of Fungicides Against Phytophthora infestans Causing Late Blight of Potato under Laboratory Condition

The experiment was conducted in laboratory in aqueous environment to guage bioefficacy of fungicides against Phytophthora infestans (Mont.) de Bary causing blight of potato (Solanum tuberosum L.) during February, 2015. Infected leaves of potato var. Kufri Jyoti were collected from field in morning hours, dig small pieces (1.0cm x 0.5cm), and were placed in petriplates containing fungicides suspension (0.1, 0.05 and 0.025%) and sterile filtered water . The plates were incubated at temperature for 48 h and observed under microscope. [5]
