Flowers Reduce use of Pesticide Spraying in Farms

Farms in the UK and Switzerland are trying a classic approach to reducing their use of pesticides: flowers. Yes, the flowers provide nutrients for insects that eat crops, but they also provide for predators. The difference in the approach for these experimental farms is how they arrange the flowers so the insects get what they need while not enough to damage the crops. Rows of flowers are spaced precisely so that insects can’t travel to far on these factory farms. Smaller farms might naturally benefit from insect proximity already.

As a bonus, the flowers make the farm a little prettier and smell better.

Similar studies have tested the same approach elsewhere. In one study in Switzerland, researchers planted poppies, cilantro, dill, and other flowers along fields of winter wheat. The plants fed and sheltered insects like ladybugs that ate the bugs that eat wheat, and ultimately reduced leaf damage 61%. The researchers estimated that choosing the right mix of flowers could increase yield 10%, making it economically self-sustaining or even profitable to keep planting flowers.

They also want to understand the economic value of the approach, and how it can be incorporated with modern farming tech. “We hope this will underpin a rethink of farming practice to include a more ecological approach to agriculture where farmers actively enhance the underlying ecological processes that benefit crop production,” they say. “We also intend to use this experimental network to demonstrate this approach to industry and to train farmers–our experience has shown that farmers often need to see these approaches in action on real farms before they adopt them.”

Less Pesticide, More Crops

The so-called “green revolution” of farming saw the rise of industrial farming which has arguably done more harm than good. Now, the tides are turning back to a more natural way to grow food. Farmers in a few West African countries have used pesticide-free farming and have found it to be rather great!

To grow healthy crops, IPPM promotes soil improvement and alternatives to chemical pesticides such as the use of beneficial insects, adapted varieties, natural pesticides and cropping practices. Marketing and food safety issues are also part of the training programme.

“Trends in agriculture over the past decades in West Africa have seen an increasing use of highly toxic pesticides in higher-value, frequently irrigated crops. There is a general lack of knowledge in the region of the negative impacts of pesticides on the production, economy and health of communities and the environment,” said William Settle, FAO Senior Technical Officer.

“Simple experiments in the field, as practised by the Farmer Field Schools, have given smallholders the means to produce in a more environmentally friendly way, to substantially increase yields and earn a better income,” Settle added.

“Capacity building at community level is key to the sustainable intensification of food production, which will contribute to increased food security and improved livelihoods in the region, an important step towards achieving the first Millennium Development Goal, reducing hunger and povert
