Common in practically all producing regions, soybean crops are attacked by several pests that can harm their productivity. One of them is the whitefly - Bemisia tabaci -, which has been a cause for concern for rural producers and professionals in the sector, due to the damage caused and the difficulty in controlling it. In the 2018/2019 harvest, the whitefly pesticide market was worth almost US$200 million.

A White fly It is a sucking insect that, during its feeding process, can introduce diseases into the sap that cause uneven development in the plant, as well as a drop in productivity, such as stem necrosis in soybeans and golden mosaic in beans.

When feeding, the whitefly excretes part of the sugar-rich sap onto the leaves, favoring the growth of opportunistic fungi, generating a darkened appearance, known as sooty mold. The entire process leads to a reduction in leaf area and, consequently, a drop in productivity.

In a network of cooperative trials organized by Embrapa (Brazilian Agricultural Research Company), the Chapadão Foundation and others 12 research institutions distributed among the Southeast, Central-West and Northeast regions were conducted 25 essays in soy in the 2017/2018 and 2018/2019 harvests.

In both harvests the efficiency of insecticides for whitefly control was proven, with gains in average productivity and efficiency of treatments with specific insecticides for whiteflies in relation to the control area without control in the trials.

With juvenoid action, Trivor – an agricultural pesticide evaluated by the soybean whitefly testing network – controls all stages of the whitefly, thus breaking the pest's life cycle. The combination of molecules that make up Trivor guarantees a strong shock effect and prolonged residual. Its technology provides consistency of results in different growing conditions. With its ready-to-use formulation, the product requires no mixing and facilitates the application process. Furthermore, Trivor It is selective to natural enemies.
