Global control
In the case of recently detected populations that are not very widespread, eradication must be implemented. This involves demarcating the area concerned and eliminating all individuals before they produce new fruit. The area concerned must be monitored for several years, until no more individuals appear.
Where large areas have been infested in the past, the spread of the infestation must be prevented. Prohibit all transport of soil from the infested area. All farm machinery and vehicles working in the infested area must be meticulously cleaned before moving on to other sites.
Chemical control
In maize crops, pre-emergence treatments with atrazine or simazine are effective against Sicyos angulatus. Post-emergence treatments with gluphosinate can be used in fields of gluphosinate-resistant maize. Other post-emergence herbicides that can be used include atrazine, primisulfuron, bromoxynil, chlorimuron, dicamba, glufosinate, glyphosate, prosulfuron, thifensulfuron and tribenuron.
In soybean crops, the herbicides that can be used in combination are: sulfentrazone, chlorimuron, metribuzin, imazethapyr, pendimethalin, imazaquine. Because S. angulatus emerges over a long period, a pre-emergence treatment with metribuzin followed by a post-emergence treatment (before the 6-leaf or 30 cm stage) with thifensulfuron or chlorimuron is effective.
Mechanical control
Deep ploughing, at a depth of more than 15 cm, considerably limits the germination of S. angulatus seeds. Shallow tillage after emergence destroys young plants, but as emergence is spread out over time, it does not prevent late germination.
Agricultural control
After an infested summer crop such as maize or sunflower, it is preferable to plant several winter crops or a perennial crop to mechanically eliminate S. angulatus populations during the summer.
Local control
Reunion: Given the risk posed by Sicyos angulatus both for sugarcane cultivation and for other crops in Reunion including chayote and orchards, it is important to systematically fight against all plant under development in a cultured plot or out of the cultivated plot. It can be done by weeding for isolated plant or through early post-emergence herbicide treatment (lower plants to 25 cm) with anti-dicot. Given the long period of germination, the targeted weed control of this weed should be repeated to eliminate all the individuals that may appear in installments during the season. The pre-emergence treatment is largely ineffective, except in anticipation of heavy infestations. Indeed, late germination are not affected and will require additional treatments of post-emergence chemical or mechanical. This species is a major threat to sugar cane and other crops in Reunion. It is essential to prevent its development on the island, and if possible eradicate it as soon as possible if we dont not want to see it join the category of invasive lianescent plants. It is therefore necessary to monitor plots, vines, borders, hedges where this plant grows preferentially.
