Beijing–Islamabad project may revolutionise tomato farming in Pakistan

Sargodha field experiments reduce chemicals by over 40 per cent while keeping yields stable

Pakistan and China have launched a joint initiative to test eco-friendly methods of tomato cultivation aimed at cutting pesticide use while sustaining yields.

The field trials were carried out in the tomato-growing area of Chak #48 NB, Sargodha, under the supervision of the University of Agriculture Faisalabad (UAF) and Yunnan University. The work was conducted through the Yunnan Fruit Vegetable Flower Integrated Pest Management International Joint Lab.

Researchers tested a system known as “3MP,” or Multidimensional Management of Multiple Pests. The method combines improved fertilization to strengthen natural plant resistance with companion cropping. Sesamum indicum was planted as a trap crop to attract harmful insects away from tomatoes, while Verbena hybrida was introduced to provide nectar for beneficial insects that feed on pests.

According to trial results, the 3MP approach reduced chemical pesticide use by more than 40 per cent. Tomato yields were maintained at levels comparable to conventional farmer practices, with some cases recording slight increases. The trials also reported improvements in fruit quality, soil health, and field biodiversity, alongside lower greenhouse gas emissions.

Dr. Abid Ali, a Pakistani agricultural scientist, explained that in the absence of officially recommended pesticides, many farmers have relied on unregulated chemical spraying, which carries risks for soil, biodiversity, and human health. He noted that the new system offers a safer alternative for growers.

Dr. Han Peng of the joint lab said the trials in Sargodha showed that integrating trap crops, nectar plants, and improved fertilization provided effective pest control without heavy dependence on chemical pesticides.

Two Pakistani PhD candidates, Mr. Jawad Hassan and Miss Sana Anjum, were closely involved in the field experiments.

The collaboration between UAF and Yunnan University began in 2023 and is part of wider international trials of the 3MP system in China, Vietnam, Thailand, and parts of Europe.

Project leaders plan to expand training through workshops with farmers, extension workers, and policymakers to support the adoption of the new system in Pakistan’s tomato farming operations.
