Pesticide use drops 25pc in last 7yrs

Bss, Dhaka

Use of harmful pesticide showed a constant declining trend, registering a phenomenal 25 percent fall in the last seven years, thanks to the Integrated Pest Management (IPM) programme and initiatives of building awareness among farmers.

The latest data of the Department of Agricultural Extension (DAE) showed that the country’s overall chemical pesticide use declined by 25 percent or 13,000 tonnes to 35,523 tonnes in 2015 from 48,690 tonnes in 2008.

The falling use of pesticides saved around Tk 650 crore during the period as the import cost for pesticide fell to Tk 180 crore in 2015 from Tk 828 crore in 2008.

“Introduction of biological pest management system like ‘sex pheromones Trap’ under the IPM helped farmers largely in containing the pest attack on some major crops,” said Hamidur Rahman, director general (DG), of the DAE.

He said farmers used to apply a huge amount of pesticides on some major vegetables like cucumber, bottle gourd, sweet gourd, tomato, okra, beans and brinjal. But the farmers are now using biological pest management system.

Rahman said rice farmers are also using “perching” method to avoid the risks of indiscriminate use of such toxic chemical on health and environment.

“Use of harmful pesticides rose alarmingly to 61,000 tonnes in the early 2008 as the farmers had no alternative to the chemical pesticides,” said Dr Syed Nurul Alam, former divisional head (entomology) of the Bangladesh Agriculture Research Institute (BARI).

A total of 18 bio-pesticide products have been provided import registration, said DAE’s pest regulatory officer Mukhlesur Rahman.

On the other hand, he pointed out that the DAE cancelled import registration for sulphur, glychomet, paraquat, carbofuran to phase out the use of hazardous pesticides.

M Abdul Bari, a Thai guava producer of Joynagar of Ishwardi, Pabna, said he spent Tk 3,000 for pesticides for a season, which was Tk 12,000 before using the IPM.

  • Soybeans were an effective trap crop, pheromone traps killed stink bugs in the trap crop, and buckwheat plants fed beneficial wasps that reduced stink bug numbers.
Agricultural Research Service

Cotton growers in the United States are concerned about native stink bugs that have attacked cotton and other crops for decades.

The green stink bug (Chinavia hilaris), southern green stink bug (Nezara viridula), and brown stink bug (Euschistus servus) continue to threaten cotton. But an Agricultural Research Service scientist in Georgia has found some environmentally friendly alternatives to insecticides.

“Cotton growers are increasingly interested in producing their crops in ways that have less impact on the environment,” says ARS entomologist Patricia Glynn Tillman, who is based in Tifton, Georgia.

The three native stink bugs are immune to the insect-killing toxins incorporated into most modern cotton varieties. Insecticides are effective, but they also kill the stink bug’s natural enemies, and they often require repeated use throughout the growing season. Organic growers can’t use conventional insecticides.

Stink bugs continue to pose a serious economic threat. Last year, they collectively infested roughly a million acres of cotton in Georgia alone, and growers there spent $12 million to control them. The bugs are a particular problem in the southeastern United States, where cotton is often grown alongside peanuts. Brown and southern green stink bugs develop in peanut fields and migrate into cotton. Green stink bugs move into cotton from nearby wooded areas.

Because of work by Tillman and others, some growers are planting “trap crops,” such as soybean and grain sorghum, to lure stink bugs away from cotton. Other options include pheromone-baited traps, which capture and kill stink bugs, and nectar-producing plants, such as milkweed and buckwheat, to feed native parasitoid wasps that attack stink bugs.

In previous work, Tillman showed the effectiveness of setting up plastic barriers between the cotton and peanut rows. Her recent study focused on whether combining a trap crop, a nectar-producing plant, and pheromone traps would control stink bugs where cotton and peanuts grow.

Tillman and her colleagues grew cotton and peanuts side by side for 2 years. In the first year, they planted soybeans as a trap crop (with and without pheromone traps), between the cotton and peanut plots. In other areas, they placed 6-foot-high plastic barriers between the plots.

In the second year of the study, they added nectar-producing buckwheat plants near the cotton. Each week of the May-to-October growing season, they counted stink bugs and stink bug eggs killed by wasps, and they documented damage to cotton bolls.

They found that the plastic barriers between peanut and cotton were the most effective tool, but the multipronged approach is an effective alternative if barriers are not feasible. Soybeans were an effective trap crop, pheromone traps killed stink bugs in the trap crop, and buckwheat plants fed beneficial wasps that reduced stink bug numbers.

“Protecting Cotton From Stink Bugs” was published in the July 2016 issue of AgResearch Magazine.

The low-tech fruit fly solution worth millions to India’s mango growers

by Jenn Bywater 03 June 2016

aims to sell 1 million traps a year.

Professor John Mumford reflects on the remarkable success of a pest-control project that’s adding value to rural life, in more ways than one.

India is the world’s biggest producer of mangoes, with around 2.5 million hectares under cultivation.

Most are grown by smallholders who rely on this crop for most of their income. There’s a healthy demand, but while good quality fruit can be sold at the farm gate for around $1.20 a kilo, damaged fruit is only good for pulp and juice, and it fetches just 20 cents a kilo.

The biggest culprit in damaging those mangoes – and their profit margin – is the ever-present fruit fly.

‘A dollar a kilo is a very big difference’

“These fruit flies lay their eggs on the surface of the fruit”, explains Professor John Mumford, Professor of Natural Resource Management; “then the maggots develop inside and once infested, they can only be sold to the processing market.”

The challenge then, is to protect the fruit while it’s growing on the trees, so that farmers can get the maximum price.

Some smallholders had tried spraying their crops, but that’s expensive and dangerous. Others had tried covering their mangoes with plastic bags, but with minimal success. As Professor Mumford explains: “What we wanted was a proven approach, adapted to meet local need.”

‘A huge collaborative effort’

“By maximising the value of their mangoes, farmers can buy essentials and send their kids to school. And it makes mango production attractive enough for the next generation, so they don’t have to move to the city and work in a factory.”

– Prof John Mumford


In collaboration with the Indian Institute of Horticultural Research and other partners across India, the team developed a simple but highly effective ‘lure and bait’ trap which kills the fruit fly with insecticide.

‘It’s very low tech’ says Professor Mumford; ‘but well conceived and well delivered.’ And the effect has been remarkable.

“Farmers are around $6-7,000 dollars per hectare better off and there are tens of thousands – and potentially hundreds of thousands doing it.”

In fact, this solution is estimated to be worth around $500 million a year to the Indian economy. And that money is staying in rural areas where it’s needed most.

The impact on farmers and their communities cannot be underestimated says Professor Mumford: “By maximising the value of their mangoes, farmers can buy essentials and send their kids to school. And it makes mango production attractive enough for the next generation, so they don’t have to move to the city and work in a factory.”

‘It was lovely to see how things had taken off’

“It’s a great example of how a small initial investment that showed a lot of promise, was followed up and moved to a bigger area.”

– Prof John Mumford


The success of this project has been particularly gratifying for Professor Mumford, given its long gestation: “It’s a great example of how a small initial investment that showed a lot of promise, was followed up and moved to a bigger area.”

In fact, its roots date back to 1998, when the Professor was awarded a small grant from the UK Department for International Development (DfID) to look at a similar problem in Pakistan. In 2000, that project won a prize – and the Professor used the money to extend the work from Pakistan into the much larger fruit growing belt in Southern India.

Seeing the impact, the Indian Government stepped in with further funding in 2005 to extend the project. They put materials into local languages, worked with the local suppliers – and it flourished. Now there are plans to move into Northern and Central India, so the potential remains huge.

‘Bring us your interesting problems’

Professor Mumford joined the staff in 1979, so he’ll be familiar to many Imperial alumni – and now he’d like to invite those alumni to “bring us interesting work”. He encourages alumni to get in touch with cases where there is a pest or disease problem that remains unsolved.

He would also be happy to hear from any alumni in large food production and importing companies who are interested in developing “a supply chain that rewards small producers”; another of his enduring passions.

Danish university researchers are to develop a drone that drops ladybirds and mites, as part of an environmentally friendly new approach to combating pests.

With their tanks filled with ladybirds, predatory mites and parasitic wasps, the drones will fly over fields and spread the insects precisely where pests are ravaging crops.

The challenge, taken on by the University of Southern Denmark (SDU), is to develop a method of spreading insects without destroying them.

Associate professor Søren Wiatr Borg from the Institute of Technology and Innovation is well underway with developing the drone’s spreader to ensure the insects land safely.

Working with living insects, however, is not easy.

“Predatory mites will eat each other if they do not have anywhere to hide, so we cover them in vermiculite, which is natural soil improving agent, so that they have a place to hide,” Borg said.

Biological plant protection is being used to great success in many nurseries, where different insects are used to fight pests.

However, the EcoDrone project, led by SDU and the company Ecobotix, will make it possible to use nature’s own weapons outside of greenhouses.

“It’s about new thinking and developing technical tools that make it easier to avoid pesticides in the future,” said SDU centre leader Brad Beach.

“One of our ambitions is for the ecodrone to make it easier to grow organic food products. It will mean lower prices on organic food and also that we can better keep up with the growing international demand for organic products.”

A release from the university also highlighted the drone could be an important tool in reaching political targets for reducing the use of pesticides and promoting organic production.

“Previously, it has been difficult and far too expensive to use nature’s own pest control methods on large areas, but by using the drones it is now possible,” Borg said.

“First and foremost, it will be strawberry fields, fruit plantations and Christmas trees we will concentrate our project on, because there is a large yield in a small area, but in the long-term it is quite conceivable that the drones could fight pests in large cornfields.”
