Plant Health

The Pacific’s fragile ecosystem is constantly at risk from invasive species, pests and diseases. It is therefore vital that sustainable and appropriate management practices are developed and utilized to ensure   sustained productive use of the land. Plant Health aims to promote these practices by utilizing its three main units, entomology, pathology and weeds in undertaking regular surveys of pests and diseases, providing information, creating awareness among farmers,  updating information databases and assisting in eradication activities. 

New technique means more profit for cabbage farmers

IPM Farm in Sigatoka Valey, Photo by Joeli.Cabbage farmers in the Sigatoka Valley have seen their incomes increase by 20–30 per cent since adopting the integrated pest management (IPM) farming technique.

The farmers are part of the IPM Brassica Project, an effective and environmentally friendly approach to pest management that relies on a combination of common-sense practices.

The project is an initiative of SPC’s Land Resources Division (LRD), with funding assistance from the Australian Centre for International Agricultural Research (ACIAR) and implemented in collaboration with the Fiji Ministry of Primary Industries.

Rajesh Raj, 33, of Raunitogo, Sigatoka — a farmer in the project — believes IPM is the way forward for farmers who want to excel in vegetable farming.

‘We thought that application of pesticides was the only way to grow vegetables successfully and we used to spray on a routine basis without realising the effect this has on the environment and the health of consumers,’ he said.

‘But with this project, we realise that not all insects are bad and that pesticides are not the only means to control harmful insects,’ he added.

Raj believes that farmers need to consider environmental and health issues before selecting the pesticides they use on their crops; unnecessary use of chemicals increases the cost of production.

IPM programmes use current, comprehensive information about the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property and the environment.

Nitesh Nand, Brassica Project officer, commented on the farmers’ keen interest in the philosophy of IPM.

‘They have realised that it is important to observe the ‘waiting period’ after an application of pesticide before harvesting,’ he said.

He added that this project is changing the farmers’ behaviour as they have seen the benefit of following IPM principles.

Another farmer, Rohit Sharma of Barara, Sigatoka, says that he has noticed a marked difference in his profit from English cabbage under IPM.

‘Now I can save on chemicals and labour: two major expenses in growing English cabbage,’ he explained.

‘Another thing that I leant in IPM is the alternate use of chemicals, which prevents resistance building up in insects. We used to use same chemicals all the time and, as a result, they became ineffective. Then we kept on increasing the amount, but not much difference was noticed.’

The Brasicca Project started in 2006 in both Fiji and Samoa and will conclude this year. After such positive results, however, another project will be started in 2012 which will extend to other vegetables and will include Tonga, Solomon Islands and Kiribati, as well as Fiji and Samoa.

This is the new ACIAR-funded Integrated Crop Management (ICM) Project; a holistic approach to crop farming that will integrate lessons learnt from the Brassica Project and will collaborate with the World Vegetable Centre to intensify vegetable intercropping.

In addition to this ACIAR project, a Food and Agriculture Organization Technical Cooperation Project will soon be implemented. This one looks at other farming methods, such as intercropping, with the aim of reducing the use of pesticides. It will involve Fiji, Tonga, Solomon Islands and Samoa. It is envisaged that both projects will start in February 2012.
