Benomyl
Physical-chemical properties: 1) Appearance: white crystalloid. 2) Melting point: 140oC (decomp.). 3) V.p.: <5.0 x 10-3 mPa (25oC). 4) KOW: logP=l.37. 5) S.g./density: bulk density 0.38. 6) Solubility: a) In water 3.6 (pH5), 2.9 (pH7), 1.9 (pH9) (all in μg/L, room temperature) ; b) In chloroform 94, acetone 18, dimethylformamide 53, xylene 10, ethanol 4, heptane 0.4 (all in g/kg. 25oC). 7) Stability: a) Decomposed by strong acids and strong alkalis ; b) Stable to light ; c) Stable under dry conditions ; d) Easily decomposed into carbendazim in water or plant media. Technical specifications: 1) Benomyl 95% tech. 2) Appearance: white fiber laxity powder. 3) a.i. content: 95.0% (minimum). 4) Moisture content: 0.1 % (maximum). 5) pH value: 5 - 7 Applications: 1) Action: systemic fungicide with protective and curative actions. 2) Uses: effective against a wide range of Ascomycetes, Fungi Imperfecti and some Basidiomycetes in cereals, grapes, pome and stone fruit, rice and vegetables. It is also effective against mites, primarily as an ovicide. Also used as pre-harvest spray or dip for the control of storage rots of fruit and vegetables. 3) Typical rates: a) On field and vegetable crops: 140 - 550 g a.i./ha ; b) On tree crops: 550 - 1100 g/ha ; c) For post-harvest use: 25 - 200 g/hl |

Cinosulfuron
1) Appearance: colorless crystalline powder. 2) Melting point: 127.0 - 135.2oC (pure). 3) V.p.: <0.01mPa (25oC). 4) KOWlogP: 2.04 (pH 2. 1, 25oC). 5) S.g./density: 1.47 (20oC). 6) Solubility: a) In water: 120 (pH 5.0), 4000 (pH 6.7), 19000 (pH 8.1) (all in mg/L, 25oC) ; b) In acetone: 36000, ethanol 1900, toluene 540, n-octanol 260, n-hexane <1 (all in mg/L, 25oC). 7) Stability: a) Decomposes above the melting point ; b) No significant hydrolysis at pH 7 - 10; considerable hydrolysis at pH 3 - 5. Applications: 1) Biochemistry: branched chain amino acid synthesis (acetolactate synthase or ALS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. 2) Action: absorbed primarily by shoots and roots, and translocated to actively growing meristematic tissue. 3) Uses: applied post-emergence to control many weeds, including Alisma, Annaal Cyperus Eleocharis, Marsilea, Potmnogeton and Sagittarla spp., Monochoria vaginalis and Sphenoclea zeylanica in transplanted, directly seeded, wet-sown, water-sown, and dry-sown rice crops, at 20 - 80g/ha. Also used in tropical plantation crops. For full weed spectrum, may need to be combined with a grass herbicide in tank-mix or sequential treatment. Product Group: Cinosulfuron |

Carbendazim
Physical-chemical properties: 1) Appearance: white crystalline powder. 2) M.p.: 302 - 307oC (decomp.). 3) V.p.: 0.09mPa (20oC). 4) KOW: logP=1.38 (pH5), 1.51 (pH7), 1.49 (pH9). 5) S.g./density: 1.45 (20oC). 6) Solubility: a) In water at 24oC, 29 mg/L (pH4), 8mg/L (pH7) ; b) In dimethylformamide 5, acetone 0.3, ethanol 0.3, chloroform 0.1, ethyl acetate 0.135, dichloromethane 0.068, benzene 0.036, cyclohexane <0.01, diethyl ether <0.01, hexane 0.0005 (all in g/L, 24oC). 7) Stability: a) Decomposes at m.p.; stable for at least 2y below 50oC ; b) Slowly decomposes in alkaline solution (22oC) ; c) Stable in acids, forming water-soluble salts. Technical specifications: 1) Appearance: white powder. 2) a.i.content: >=98%. 3) Water: <=0.25%. 4) O-PDA: <=0.2%. 5) Acidity (H2SO4): <=0.2%. Applications: 1) Action: systemic fungicide with protective and curative actions. 2) Uses: control of a wide range of diseases on cereals, fruits, grape, oilseed rape, sugar beet, ornamentals and vegetables. Application rates vary from 120 - 600g/ha depending on crop. A seed treatment (0.6 - 0.8g/kg) will control Tilletia, Ustilago, Fusarium and Septoria in cereals and Rhizoctonia in cotton. Also shows activity against storage diseases of fruit as a dip (0.3 - 0.5g/L). In addition, it can be used as a mildew-proofing agent in textiles, papermaking, leather and paint.
