“…In comparison with bare soil, jassid population was significantly lower in silver mulch, black plastic mulch as well as wheat straw mulch on a research carried out in Chitwan district of Nepal (Dahal et al, 2020). In a 2 years study on the integrated impact of reflective mulches, plant resistance and insecticide use, lower number of whitefly eggs, nymphs and adults were observed in reflective silver mulch treatment in comparison with organic straw mulch and no-mulch treatments (Nasruddin et al, 2020).…”

Integrated Pest Management is a sustainable and holistic approach based on ecological, biological, physical and chemical tactics for controlling pests in the field that, in any way, minimizes risk towards the health and environment. IPM methods involve identifying and knowing the characters of possible pests, making efforts to prevent prevalence, judgment of severity of pest-disease infestation through scouting and monitoring techniques. This paper highlights some of the already practiced strategies and experiments with interpretation of results obtained in various field conditions suggesting wider implications of IPM for managing pests in our fields. The review collects and studies some of the basic and commonly adopted cultural practices like clean and healthy crop growth, trap crop plantation, crop rotation, crop combinations etc. Cost effectiveness, ease of execution, instantly observable results etc are some unattainable aspects affecting IPM adoptions yet farmers seem somewhat encouraged towards sustainable and healthy production in recent years. It is necessary to know about crop and pest biology, ecology, phenology and their links/interaction to successfully implement cultural practices.

“…The current paper thus, intends to provide science-based evidence to support the efficacy of traditionally used practices such as jholmal and straw mulching by comparing the yield and rate of disease and pest infestation in selected agriculture crops. The use of jholmal and straw mulching, both qualify as ecosystem-based adaptation practices for farm management based on a framework and criteria developed by Vignola et al [ 13 ] that considers: a) conservation, restoration or management of ecosystem processes or services; b) improve the ability of crops to maintain crop yields; and c) appropriate for smallholders, all of which help to increase food security and income, utilize traditional/local knowledge, and are comparatively cost effective methods [ 6 , 7 , 14 , 15 ].…”

Ecosystem-based adaptation for increased agricultural productivity by smallholder farmers in Nepal

The impacts of climate change are evident in the agriculture sector globally. These impacts are more severe and pronounced in a mountainous country like Nepal due to the high reliance on agro-economy and subsistence-based livelihoods by smallholder farmers that increase vulnerability and risks. Several ecosystem-based adaptation measures have proved to build the adaptive capacity of both agro-ecosystems and smallholder farmers by offering simple and affordable technologies however, these are yet to be prioritized by policy and programs for scaling. In this paper, we provide science-based evidence to traditionally used practices, such as jholmal (locally prepared bio-fertilizer and pesticides) and straw mulching by comparing their efficacy in terms of yield and reduction in disease pest infestation. The study was conducted in Kavre district of Nepal during 2017 and 2018 using participatory on-farm field trials for jholmal and straw mulching designed separately with Randomized Complete Block Design for selected vegetable crops like bitter gourd and tomato. The application of jholmal showed significant increase in bitter gourd yield both at the foothill and hilltop sites compared to the farmer’s business usual practice (in 2017 and 2018, bitter gourd yield increased by 30.5% and 31.1% in foothill, while 26.6% and 28.7% in hilltops respectively). Further, a significant reduction on fruit infestation was observed in jholmal treated plots. Similarly, there was increase in tomato yield when straw mulch was used compared to the non-mulched trials (in 2017 and 2018, tomato yield increased by 16.5% and 20.3% respectively). These findings suggest that traditionally used practices have scientific basis and offer simple, affordable and climate friendly practices to improve the health of agro-ecosystem while supporting smallholder farmers to adapt to adverse impacts of climate change and build socio-ecological resilience. These practices can be also customized depending on the local context for wider adoption and scaling across Nepal and elsewhere as ecosystem-based adaptation measures for smallholder farmers.

“…Jassids inject toxin into infested plants thus leads to leaf yellowing and hopper burn symptom (Kadu et al, 2018). Dahal et al (2020) reported that jassids can cause 35-40% of crop yield losses in okra and their damage may reach 60-70% at optimum condition. The presence of certain characteristics in host plants can attract or deter the infestation of jassid.…”

Morpho-Biochemical Characteristics of Brinjal Germplasms Affect the Abundance And Infestation of Jassid

The tropical vegetable, brinjal is cultivated throughout the year in Bangladesh but the crop is infested by a number of insects including jassid. This study investigated the effects of different biophysical and biochemical characteristics of twelve brinjal germplasms on the abundance and infestation of jassid. The experiment was conducted during September 2018 to March 2019 in Gazipur, Bangladesh with twelve brinjal germplasms namely BD-7320, BD-7328, BD-9952, BD-10154, BD-10158, BARI Begun-1, BARI Begun-4, BARI Begun-5, BARI Begun- 6, BARI Begun-7, BARI Begun-8 and BARI Begun-9. The incidence of jassid was recorded from 3rd December to 26th March, and the lowest population was found on BARI Begun- 6. Among the biophysical traits, plant height, number of branch and leaf per plant, and leaf area exerted significant positive correlation; whereas trichome on lower and upper surfaces of leaf, spine per stem and leaf showed significant negative correlation with the abundance of jassid. On the other hand, moisture, reducing sugar, total sugar and protein content of the leaves and fruits, chlorophyll content of the leaves exerts significant positive correlation but ash and pH contents of the leaves and fruits were negatively correlated with the abundance of jassid. Jassids showed the lowest level of leaf infestation on BARI Begun-6, which could be for further analysis to develop jassid resistant brinjal. SAARC J. Agric., 19(1): 81-91 (2021)
