In contrast with systemic insecticides that travel only one way, such as the case with imidacoprid, spirotetramat-enol being a systemic metabolite with double lanes can protect new leaves generated after the application and it can even protects the roots [1, 18]. 0000136421 00000 n

), psyllids (Psylla spp., Paratrioza cockerelli), mealybugs (Pseudococcus spp., Planococcus spp. It is important to note that the above mentioned processes depend on the chemical structure and the physical properties of the compound used, as well as the soil, the vegetation, and the climatic conditions [22]. However, these same researchers [22] observed that spirotetramat under aerobic soil conditions will degrade rapidly after 1-2 days, dissipating more than 90%. 0000001172 00000 n
Being mobile through both xylem and phloem plant transport systems, Movento provides not only long lasting, effective protection to all areas of the plant, but can also protect new shoots growing after application. It was also observed that the way of contact of the insecticide influences its effectiveness on the control of the insects; it has a major effect if spirotetramat is ingested orally than if it is by direct contact with the insect [1, 8].

After Movento has been applied to the crop, the active ingredient, spirotetramat, penetrates into the leaf tissue. Evidence exists indicating that compounds derived from the structural unit of tetramic acid have biological activities across a wide spectrum; antibiotic tirandamicin A and the phytotoxin of tenuazonic acid are examples of this type of compounds found in nature [3]. 0000003333 00000 n

For concentrate spraying adjust dilution rate accordingly.. Its the only insecticide thats truly systemic, meaning that you can spray it on the leaves and it goes down to the roots and then comes back out in the plant, Morris said. It is essential to understand the course of action and toxicity of pesticides through the development of methods and procedures of bioassays because some chemicals (such as organophosphates, carbamates, and pyrethroids) can express their toxicity in a maximum time frame of 48 hours; other reduced risk pesticides such as spirotetramat, spinetoram, novaluron, chlorantraniliprole, and flubendiamide express their toxic effects several days after treatment [11]. After a foliar application of spirotetramat, it enters the plant and transforms to its metabolite enol, along with the metabolite ketohydroxy, which are the two main products of degradation. Considering that within 14 days after the application of spirotetramat it degraded to concentrations below 0.5 g kg-1, the possibility of the accumulation of residues in the soil one year later after the first application is low [22, 27]. hbbd```b``3@$d9 Reference [24] determined the metabolism of spirotetramat in apple, cotton, lettuce, and potato (Table 2). 0000010733 00000 n

Lipids are particularly significant as fundamental components for the manufacture of membranes in insects, which form the basic structural architecture for every cell in an insect's body. The buildup of whiteflies concerns growers because they feed on vegetables and transmit two viruses: cucurbit leaf crumple virus and cucurbit yellow stunting disorder virus. It has also been observed that on female adult whiteflies (B tabacco) treated with spirotetramat (40 and 200 ppm), the number of eggs produced is a function of the applied doses (major reduction 90% and 60%), including a concentration of 8 ppm, 80% of the eggs do not hatch. However, in apples, they detected a fourth metabolite, BYI08330 monohydroxy, with a considerable percentage (around 15.6%); meanwhile in the potato tuber, the main metabolite was BYI08330-enol, along with the absence of the father compound.
