The insecticide Taura 200 EC is the new tool in Brazil for control of whitefly (Bemisia tabaci). The product, based on the active ingredient pyriproxyfen, was registered by Brazilian agrochemical company Cropchem in early 2019.
According to the manufacturer, Taura 200 EC fights whitefly eggs and nymphs, one of the most harmful pests attacking soy, cotton, tomato and citrus plantations. The product will be marketed with 200 g/L of the active ingredient pyriproxyfen, twice the concentration found in the competing products in the Brazilian market.
The insecticide provides a contact and translaminar action with emulsifiable concentrate formulation (EC). It is a juvenile physiological insecticide, analogous to the juvenile hormone, regulator of insect growth. The product acts mainly on the eggs and nymphs, causing disturbance in the hormonal balance, preventing the insects of the young forms to become adults. The females that come in contact with the product place unviable eggs and also decrease the posture.
Taura 200 EC is also recommended for use in eggplant cultures against tripes (Thrips palmi), and in the control of coffee leaf miner (Leucoptera coffeella), as well as citrus psyllid (Diaphorina citri), Selenaspidus articulates and Parlatoria cinerea.
The Cropchem insecticide is also registered for use in beans, gerbera, apple, watermelon, melon, cucumber, cabbage, rose, tomato and grape crops.
The raw material of the Taura 200 EC is supplied by several companies, the majority coming from China. Among the participating companies are Jiangsu Flag Chemical Industry Co. Ltd., Rudong Zhongyi Chemical Co., Ltd., Nortox SA, Tagros Chemicals India Pvt. Ltd., and Wasion Crop Science and Technology Co., Ltd.
