phytotoxicity

Simazine (Tafazine) is a chlorotriazine herbicide and pesticide. Simazine may lead to testicular degeneration, neuroendocrine disruption, mammary cancer, and fetal developmental delays.

Tulipalin A (α-methylene-γ-butyrolactone) (2-Methylenebutyrolactone) which has some phytotoxicity is a natural compound extracted from Tulipa gesneriana.

Hydrolyzed Fumonisin B2 (HFB2) is a hydrolysis product of fumonisins (HF) that retains biological activity and exhibits phytotoxicity.

Fludioxonil is employed to manage the growth of axillary buds (suckers) following the topping of tobacco plants. Its mode of action includes a localized systemic effect, contact action, and phytotoxicity.

Destruxin B2 is a cyclic hexadepsipeptide mycotoxin that has been found in M. anisopliae and has antiviral, insecticidal, and phytotoxic activities.1,2,3 It inhibits secretion of hepatitis B virus surface antigen (HBsAg) by Hep3B cells expressing hepatitis B virus (HBV) DNA (IC50 = 1.3 μM).1 Destruxin B2 is toxic to Sf9 insect cells in an electric cell-substrate impedance sensing (ECIS) test with a 50% inhibitory concentration (ECIS50) value of 92 μM.4 It is also phytotoxic to B. napus leaves.3 |1.
