China-based XAG has announced it has introduced automous drones to improve pest control efficacy against disease caused by fall armyworms, the company said.
XAG is among the first to introduce fully autonomous drones in some of the most affected countries, such as Zambia, South Africa, Vietnam and China, to improve the control efficacy that has originally been limited to manual spraying. XAG has discovered that in the worst hit Africa and Asia, the absence of smart devices, the unique natural habits of fall armyworm and farmers´ lack of professional expertise have resulted in a rapid large-scale infestations.
Fall armyworms are a highly destructive pest species native to tropics and sub-tropics of the Americas, they have aggressively invaded more than 100 countries and devastated millions of hectares of crops since 2016. It is the ´crop-devouring monster´ that attacks over 80 crop varieties but has high preference for maize. At its larval stage, it can cause great damage to the leaf, stem and cob of the maize plant and munch the entire cornfield almost overnight.
At the end of its lifespan, as a moth, this pest can fly up to 100km in one night and lay as many as 1,000 eggs during its lifetime. With strong migration and reproductive abilities, fall armyworms crossed the Atlantic for the first time and landed in Africa in early 2016, then quickly spread to most Asian countries in July 2018. As for Africa alone, the annual yield loss of the 12 maize-producing countries is estimated at USD 4.6 billion in 2018.
XAG´s precision UAS spraying solution can suppress the encroachment of fall armyworm through large-scale emergency action involving minimal physical labour. Drone swarm operation can besiege the infested croplands and kill the pests en mass within a large area to reduce moth migration. The drone can safely operate after sunset, working on the nocturnal pests.
XAG is an agriculture technology company and industrial UAS manufacturer that developed drones, internet-of-things (IoT), artificial intelligence (AI) and other digital farming tools for precision seeding, fertilising and spraying.
