The available materials do not provide adequate control, and pymetrozine has the added benefit of providing another mode of action … Not affiliated In: Georghion GP, Saito T(eds) Pesticide resistance: strategies and tactics for management. Pymetrozine is a feeding inhibitor of Homoptera, in preventing transmission of cauliflower mosaic caulimovirus by the aphid species Myzus persicae (Sulzer). Animal metabolism. Based on previous studies of symptoms in the locust, the feedback loop controlling the femur–tibia joint of the middle leg was chosen to examine possible targets of the insecticide. The mode of action of pymetrozine in insects has not been precisely determined biochemically, but it may involve effects on neuroregulation or nerve-muscle interaction. Neonicotinoids, like nicotine, bind to nicotinic acetylcholine receptors (nAChRs) of a cell and trigger a response by that cell. These keywords were added by machine and not by the authors. 6. Pestic Sci 23 149–156, Wyss P, Bolsinger M (1997) Translocation of pymetrozine in plants. This is illustrated by feeding inhibition, as in aphids, but also by unique intoxication symptoms (Kaufmann et al., 2004). Pymetrozine (CGA 215′944) is a new insecticide, highly active and specific against sucking insect pests (Flückiger et al. 0000001456 00000 n Active Ingredients: Pymetrozine 50.0% Insecticide Mode of Action: 9BInsecticide Class: Pyridine Azomethine Derivatives EPA Signal Word: CAUTION / PRECAUCIONApplication Rate Range: (see label) Container Size(s): 6 x 2.5 Oz. In: Minks AK, Harrewijn P (eds.) 0000092762 00000 n Mode of action. Insecticides plays a pivotal role in pest management, Mode of action of insecticides is very important toxicological aspects to be clearly understood to develop a strategic plan against pests. Uses Control of aphids and whitefly in vegetables, potatoes, ornamentals, cotton, deciduous and citrus fruit, tobacco, hops; both juvenile and adult stages are susceptible. - Mechanism of Action & Protocol. The compound appears to have great promise in integrated pest management (IPM) programs due to its high degree of selectivity, low mammalian toxicity, and safety to birds, fish, and nontarget arthropods. This service is more advanced with JavaScript available, Insecticides with Novel Modes of Action Instead, pymetrozine strongly suppresses reproduction of these pests by perturbing oviposition, and its insecticidal effect is measured by counting the number of offspring (Tsujimoto et al., 2016). Pymetrozine Uses Control of Aphids and Whitefly in vegetables, potatoes, ornamentals, cotton, deciduous and citrus fruit, tobacco and hops; both juvenile and adult stages are susceptible. Harrewijn P, Kayser H (1997) Pymetrozine, a fast acting and selective inhibitor of aphid feeding. 0000003004 00000 n The mode of action of pesticides is extremely fascinating because the subject covers so many fields of biology and chemistry and has many practical implications. Mechanism of action. Proc 1992 Brighton Crop Prot Conf—Pests and diseases, vol 1, pp 43–50, Flückiger CR, Senn R, Buholzer H (1992b) CGA 215–944-opportunities for use in vegetables. 1992a,b). The applicant states that the mode of action of Afidopyropen may be similar to another insecticide, pymetrozine (see Substance summary below), which is in Schedule 5 of the Poisons Standard as follows: Schedule 5; PYMETROZINE. Pesticide properties for Pymetrozine, including approvals, environmental fate, eco-toxicity and human health issues ... Mode of action: Selective, neural inhibition of feeding behavior that eventually starves insect.

Afidopyropen is not currently scheduled and has not been previously considered for scheduling. Morita et al. This process is experimental and the keywords may be updated as the learning algorithm improves. 89 0 obj << /Linearized 1 /O 91 /H [ 861 595 ] /L 205968 /E 93491 /N 22 /T 204070 >> endobj xref 89 21 0000000016 00000 n Fulfill11 Insecticide (EPA Reg.

On rice, applied at 15-75 g/ha (foliar), 75-100 g/ha (dust) or 300-400 g/ha (soil treatment). EPA has assigned a cancer classification of “likely” to pymetrozine and calculated a Q1* value. Uses Control of aphids and whitefly in vegetables, potatoes, ornamentals, cotton, deciduous and citrus fruit, tobacco, hops; both juvenile and adult stages are susceptible. Pymetrozine Technical (EPA Reg No. (2007)) also described flonicamid as having a mode of action distinct from pymetrozine, since treated insects did not display contractions of the foregut characteristic of pymetrozine (Kaufmann et al., 2004), but exposed aphids did display staggered walking, with their legs extended at the femur/tibia and tibia/tarsus joints.
