How Can Mite Based Problems be Solved?
Efficient control of various mites in outdoor crops has become problematic. The reasons a multiple, but the question remain: how can mite based problems be solved?
Spical Ulti-mite™ (containing Neoseiulus californicus)
Crops: Citrus, table grapes, pomefruit and stonefruit
Recently there has been a surge in citrus red mite (Panonychus ulmi) infestations across South Africa. Spical Ulti-mite™ has proven to be highly efficient as a frontline agent to combat both citrus red mite and red spider mites (Tetranychus spp.) in citrus. The pomefruit and stonefruit industry has also benefitted tremendously from the deployment of Spical Ulti-mite™, mainly to control early infestation of red spider mites (Tetranychus spp.).
Spical Ulti-mite™ can also be used in conjunction with other predatory mite products like Spidex™ (Phytoseiulus persimilis).
Every year the list of agrochemicals permitted for the use in export fruit production decreases. This leaves little room for chemicals for the control of mealybug. Are there biological solutions for mealybug?
Citripar™ (Anagyrus pseudococci) a parasitic wasp has established itself as the cornerstone on any mealybug control strategy. Due to the adaptability of this highly efficient parasitic wasp, Citripar™ can be used on various crops grown outdoor and indoors. Various phases in the life cycle of mealybugs are controlled, leading to excellent control. Another advantage is that the cost of application is highly competitive with chemical options.
Citripar™ can also be used in conjunction with Permipar™ (Coccidoxenoides perminutus) a smaller parasitic wasp to control earlier phases of mealybug. Predatory beetles such as Cryptobug™ (Cryptolaemus montrouzieri) is mainly deployed once egg packs of mealybugs are present.
Citrus is major export fruit. Citrus red scale (Aonidiella aurantii) is a major pest of most citrus types. With increasing pressure from international buyers, reduced MRL fruit are demanded. How can this be achieved?
A well planned IPM strategy will result in “no” or “low” MRL fruit. Such a strategy relies on the utilisation of well proven biological control products. One such product is Aphytis™ (Aphytis melinus) a parasitic wasp used in all major citrus production countries. South Africa is no different. Over the past three seasons Aphytis™ has proven itself under African conditions as a strong and reliable solution. Crop spraying late in the season is eliminated through the use of Aphytis™ leading to increase profits.
What agronomic benefits does it provide to follow an IPM approach?
There are several benefits to an IPM approach, to name a few: Increased pesticide restrictions,
human health effects, minimize residues on food, reduce adverse environmental effects, delay resistance, increase production and quality.
What is the key to a successful IPM approach?
Frequent and systematic scouting is crucial to IPM success. Early detection of pests and diseases leads to timely action when pest or diseases levels are low and actions most effective. Observing eyes, sticky traps, pheromone traps and magnifying glasses are indispensable tools for scouting and monitoring.
