![]() ![]() Seasonal warning: This innovation will enable the chain of actors and decision makers to support prevention against high LB risk, to provide support and resources in advance to prevent the problem and potential losses. Regional platform of specialists: Technical capacity building will be a major step forward in solving the problem and implementing management measures with a sustainable approach in the 4 participating countries.Įarly warning system: This decision support tool will give the possibility to reach new users with information for efficient and sustainable disease management, under new cropping conditions, reducing losses and improving farmer socioeconomic condition. Applied research capacities will be strengthened to incorporate them into member countries' production systems. This proposes the 50% reduction of the use of pesticides necessary for the control of LB, in a safe and efficient way, and the implementation of an IPM strategy, according to the environmental condition and production system, thus reducing costs by at least 20%. This information, together with integrated management training and good agricultural practices, will encourage adaptation and mitigation to climate change for the sustainable intensification of potato production. Using early warning-based information will help farmers perform chemical control in a timely and efficient manner and only when needed. This proposal proposes the formation of a platform of specialists in potato LB, with the aim of developing and implementing an early warning system as tools to support decision-making in small farming production systems, according to available technology in each country, and able to reduce the losses caused by this disease. Farmers, therefore, use pesticides excessively and inappropriately, increasing the environmental impact and risk to the health of users. Today, LB is considered a re-emerging disease in this crop, due to pathogen variability and climate instability that favors its presence and dispersion, with a high incidence and severity. USABlight was created with funding from UDSA’s Agriculture and Food Research Initiative (AFRI) Competitive Grants Program Grant 2011- 68004-30154.Potato is a major crop in Latin America and is the main food in small farming, it is native to America as well as the causal agent of Late Blight (LB), P. Click here for an informative pamphlet on the disease Knowing where the disease is present can help improve the efficacy of fungicide treatments. Yield losses caused by late blight and the cost of control measures have been estimated to exceed 6.7 billion dollars annually and the disease is a major threat to food security worldwide. Under favorable weather conditions, tomato and potato crops can be destroyed within days if left untreated. Late blight of potato and tomato caused by Phytophthora infestans is a devastating disease worldwide and led to the Irish potato famine in 1845. There are also useful links to a decision support system, and information about identification and management of the disease. You can report disease occurrences, submit a sample for genotyping, observe current and past disease occurrence maps, and sign up for text disease alerts in your area. Welcome to USABlight, a national website that acts as an information portal on late blight. ![]()
