Allan Hruska of the Food and Agriculture Organization has examined published studies to see which management options are most likely to help smallholders tackle the devastating crop pest fall armyworm
As part of CABI’s mission to help farmers grow more and lose less, we have been funded by USAID – via the United States Department of Agriculture (USDA) – to help Pakistan improve its sanitary and phytosanitary (SPS) systems and therefore open up its fruit and vegetables to more high-end global markets that were previously untapped. Currently these products only contribute 13% of the country’s export but improvements to its SPS capabilities could see this number rise significantly.

However, concern about invasive species and the search for methods to sustainably manage them has a much longer history, dating back to the 19th century
Genetically modified crops containing a toxin gene from the bacterium Bacillus thuringiensis have been used by farmers for 11 years now. These Bt crops were designed to give the plants resistance to important pests. But might they also be harming non-target invertebrates? A study by Steven Naranjo of the US Department of Agriculture’s Agricultural Research…
