It is used for the control of three wheat scab, cereal smut, cotton seedling disease, rape sclerotinia, rice sheath blight, rice blast, sugar beet brown spot, etc. Carbendazim can be absorbed by plants and transferred to other parts by conduction, interfering with the mitosis of bacterial cells and inhibiting their growth. It has a wide bactericidal spectrum and is usually processed into powder, wettable powder and suspending agent for seed treatment or foliar spraying, and is used to prevent and control various fungal diseases of grain, cotton, oil, fruit, vegetables, and flowers. Can be used for fruit preservation.3,4-Methylenedioxyphenylpropan-2-one or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via oxidation using the Wacker oxidation or peroxyacid oxidation methods. MDP2P is unstable at room temperature and must be kept in the freezer in order to be preserved properly. MDP2P is a precursor in the chemical synthesis of the methylenedioxyphenethylamine (MDxx) class of compounds, the classic example of which is 3,4-methylenedioxy-N-methylamphetamine (MDMA), and is also an intermediate between the MDxx family and their slightly more distant precursor safrole or isosafrole.
