Stockholm convention approves non-chemical as well as chemical alternatives

The Conference of Parties to the Stockholm Convention on Persistent Organic Pollutants, meeting in Geneva, approved non-chemical as well as chemical alternatives to endosulfan on Thursday. The non-chemical alternatives were proposed in a significant departure from past practice. The evaluation of non-chemical alternatives, as accepted by the conference, consists of an ecosystem-based approach to pest management as well as technical interventions.

In the present study an indigenous biopesticide formulation (BPF) comprising easily accessible botanicals along with cow urine, was evaluated for its efficacy against insect pests of tomato crop under field. BPF gave promising results in controlling tomato fruit borers and afforded substantial yield of the produce. The BPF treatment could control 70–80% of fruit borers compared to check plots, resulting in enhanced fruit yield of 35 tonnes/ha as compared to 15 tonnes/ha
in the check plots. The main aim of this study was to reduce the load of synthetic chemical pesticides and

Biodiversity is a commonly used word to describe the variety of life on earth. It refers to the wide range of living organisms: microbes, plants, animals and their habitats. Biodiversity on organic farms accounts for efficient nutrient recycling and effective insect management. An organic farm is a balanced system where the problem of insects is well taken care of by their natural
predators. Therefore, most farms rich in biodiversity possess greater resilience and are able to recover more readily from stress such
as drought, pests, diseases, epidemics, etc.

A decade ago, Chandra Pradhani, a Paraja tribal of Nuaguda village in Kundra block of Odisha's Koraput district, would migrate to neighbouring Andhra Pradesh to earn a living as a brick kiln worker. He no longer does this. Today, he is feted by the nation. He was one of the tribal farmers honoured by prime minister Manmohan Singh at the 99th Science Congress held in Bhubaneswar in January. It is the hard labour and traditional agricultural techniques of tribal families that have helped put Koraput on the map of world agriculture.

Effect of the leaf extracts of Alstonia scholaris and Calotropis procera on infestation and damage of the fruit fly in bitter gourd was studied.

Stagnating yields, negative impact on environment, soil health and farmers' economy were some of the side effects of green revolution and provided fuel to search new and unexploited areas to ensure increased productivity through eco-friendly or evergreen farming.

Demand for effective bio-pesticides rising across the globe

Rapidly emerging insecticide resistance is creating an urgent need for new active ingredients to control the adult mosquitoes that vector malaria. Biopesticides based on the spores of entomopathogenic fungi have shown considerable promise by causing very substantial mortality within 7–14 days of exposure. This mortality will generate excellent malaria control if there is a high likelihood that mosquitoes contact fungi early in their adult lives.

This article studies the development of the Non-Pesticidal Management Project (NPM) that emerged in the late 1980s in Andhra Pradesh's Warangal district of the semi-arid region Telengana as a response to accumulating agrarian distress, when chemical pesticides did not help to counter massive pest infestations.
