- Debug the Fall Armyworm

GUANGZHOU, China, Aug. 30, 2019 — (PRNewswire) —  Facing dreaded pest disease caused by fall armyworms, 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.

Fixing the 'Crop-devouring Bug' with Drone

Chemical control remains one of the most widely deployed methods to contain the spread of fall armyworms. However, most farmers usually resort to traditional sprayers and, in many cases, find the effect disappointing while exposing themselves to the hazard of pesticide poisoning. Manual spraying not only fails to meet the demand for a quick, emergent control over the ravenous, fast-moving fall armyworm, but also makes it difficult for pesticides to contact the hidden caterpillars because of uneven hand sprays.

Given the situation, XAG's precision UAS spraying solution can suppress the encroachment of fall armyworm in time, through effective 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.

A special atomisation spraying mechanism, features micron-level droplets and powerful downdraft, is designed to achieve uniform applications of ultralow-volume pesticides. Both sides of the leaves and the central part of crops, where the pests conceal themselves, can be more precisely targeted. This not only increases fall armyworm's exposure to chemicals but also cuts down 30% pesticide use and 90% agricultural water.

Going Global to Halt the Fall Armyworm Attack

In Zambia, Sunagri Investment Zambia Limited, a local crop-protection service provider, has utilised XAG's P Series Plant Protection UAS for aerial spraying against fall armyworms during the last maize growing season. A series of field experiments and practical operations were conducted on three commercial farms, covering approximately 200 hectares of infested croplands where yield loss was avoided after chemical treatments.

Later in China, where fall armyworms have rapidly made their way to over 21 provinces and infested nearly 600,000 hectares of farmlands, XAG has consistently worked with an international agrochemical company, local distributors and the government to provide well-validated chemical control based on precision UAS spraying technology.

For instance, in Guangxi Province, XAG and Bayer Crop Science initiated their first-ever emergency control this April to help local smallholders ward off fall armyworm on maize and sugarcane fields. Results showed that drones, loaded with low-toxicity synthetic insecticide, effectively killed the pests and achieved a larval mortality as high as 98%.

This July, in Yunnan Province, XAG's local distributor, Qiushi Aviation Technology Company, assembled a team of professional drone operators and participated in the government-led operation with seven P Series UASs. The team has successfully managed pest damage to its minimum on nearly 270 hectares of croplands.
