FLUDIOXONIL, a phenylpyrrole derivative, is a broad-spectrum fungicide for control of a range of diseases on fruit and vegetables. It may represent a health threat to consumers.

Fluridone, an herbicide that used for controlling invasive aquatic plants such as hydrilla in surface water bodies. It inhibits carotenoid synthesis in targeted plant species, preventing photosynthesis and ultimately causing mortality. This compound contains a 4(1H)-pyridone and a trifluoromethyl-benzene moiety, which are also present in molecules with analgesic and anti-inflammatory properties. Experiments on rodents have confirmed that fluridone could represent a new prototype of an anti-inflammatory drug.

Isoxaflutole is a selective herbicide approved for control of certain broadleaf and grass weeds in field corn and soybean. Isoxaflutole is the first member of a new structural class of herbicides called the isoxazoles. Isoxaflutole works by preventing the biosynthesis of carotenoid pigmentsin both broadleaf and grass weeds. Without carotenoid pigments, chlorophyll pigments are damaged by the sun, and the plant eventually dies. Isoxaflutole is effective against weeds resistant to other herbicide classes such as glyphosate and atrazine. Isoxaflutole was registered conditionally from 1998 to 2004 for weed control in field corn. Isoxaflutole exhibited low acute toxicity via oral, dermal, and inhalation routes of exposure and it is not a dermal sensitizer. In long-term studies via the oral route, isoxaflutole caused ocular toxicity in rats, hepatotoxicity (including liver tumor formation) and thyroid tumors in rats and mice, and hematotoxicity (toxicity to blood) in dogs and mice at high doses. The liver and ocular toxicities observed in rats were consistent with the mode of action of isoxaflutole in mammals (i.e., inhibition of the hepatic enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD)) that leads to a buildup of tyrosine in the blood and the eye.

Acetamiprid is a carboxamidine that is acetamidine in which the amino hydrogens are substituted by a (6-chloropyridin-3-yl)methyl and a methyl group while the hydrogen attached to the imino nitrogen is replaced by a cyano group. It has a role as a neonicotinoid insectide, an environmental contaminant and a xenobiotic. It is a monochloropyridine, a nitrile and a carboxamidine. It derives from a 2-chloropyridine. Acetamiprid is an insecticide that is currently approved for EU use. It is highly soluble in water and is volatile. Based on its chemical properties it would not be expected to leach to groundwater. It is not persistence in soil systems but may be very persistent in aquatic systems under certain conditions. It has a moderate mammalian toxicity and it has a high potential for bioaccumulation. Acetamiprid is a recognised irritant. It is highly toxic to birds and earthworms and moderately toxic to most aquatic organisms. Acetamiprid is a nicotinic agonist that reacts with nicotinic acetylcholine receptors (nACh-R). The activation of the nACh-R receptors causes hyperactivity and muscle spasms, and eventually death.

Tricyclazole is a systemic fungicide for control of Pyricularia oryzae on rice. Tricyclazole protects plants from infection by P. oryzae by preventing penetration of the epidermis by the fungus. The compound acts by inhibiting melanization within the appressorium, thus causing a lack of rigidity in the appressorial wall. Tricyclazole has no apparent effect on spore germination although sporulation is reduced. Tricyclazole is not curative but is protective in its activity. Tricyclazole can influence the pathogenic ability of aspergillus aculeatus by damaging the cell structure of hyphae and conidia, reducing the melanin production, and altering the expression of pathogenic-related gene. Tricyclazole toxin can impair testosterone secretion and the testicular structure in mice, leaving an adversely effect on sperm production system.

Triclopyr-butotyl is an ester form of selective systemic herbicide triclopyr. Prolonged or frequently repeated skin contact with triclopyr-butotyl may cause allergic skin reactions in some individuals. Animal and in-vitro genetic studies were negative for triclopyr-butotyl. Triclopyr-butotyl did not cause cancer in laboratory animals.
