Environmental factors influencing the population of whitefly and leaf curl disease incidence in chilli

Abstract

Randomly selected five plants from each plot in rectangular cage were observed population of white fly and disease intensity of leaf curl virus at weekly interval Meteorological data ., maximum temperature, minimum temperature, relative humidity, total rain fall and wind velocity were obtained from the meteorological observatory viz Chilli leaf curl disease, one of the most devastating disease in chilli, is transmit through whitefly Genn under favorable environmental conditions (Bemisia tabaci) Positively correlation of white flies population with minimum and maximum temperature. The population density of whitefly was decreased due to heavy rainfall

Eco-Friendly Approaches for Controlling Sucking Pests in Chili (Capsicum Annuum L.)

“…Such effectiveness of botanicals like NSE 5%, Neem oil 2% and Azadirachtin 1500 ppm in minimizing the incidence of Leaf Curl Index (LCI) on chilli leaves has been demonstrated by several workers like Pandey et al (2010), , Chakraborty and Nath (2015), Chaubey et al (2017), Zeeshan and Kudada (2019). These studies collectively affirm the efficacy of NSE 5%, Neem oil 2% and Azadirachtin 1500 ppm in reducing leaf curl disease in chilli plants, supporting, and confirming the present findings.…”

BIOFOR Biological Aerated Filter in Environmental Biology

“…In anoxic water, organic pollutants will produce a large number of odorous substances such as hydrogen sulfide, ammonia, amine, mercaptan under the anaerobic degradation of anaerobic microorganisms [14][15]. After a series of biochemical reactions, the acid hydrolysates of humic acid and fulvic acid form a large number of smelly ammonia and extremely smelly thioether compounds [16]. When there are a large number of actinomycetes in the water, they can use the mercaptans and thioethers generated by the anaerobic decomposition of sulfur-containing proteins for biological metabolism to produce stinky 2-methyl isozyl alcohol and kaempferol.…”

In addition, algae will also form after death and cracking β-Odor substances such as ionone (aldehyde) [16][17]. Among them, the biochemical reactions of NH3, H2 S, etc.…”

Assessment of Incidence of Chilli Leaf Curl Virus, Role of Environment and Disease Management

“…Chilli (Capsicum annum L.) is an important commercial and spice crop belonging to the family Solanaceae and is a native to South America (Mexico) where it was cultivated around 6000 years ago and was brought to Asia during the 16 th century by Portuguese navigators. Chilli can be grown best at temperature ranges from 20-30°C but its growth and yield suffer when temperature exceeds 35°C or drops below 15°C for extended periods [1].…”
