Carbendazim APPLICATIONS
Biochemistry Reported to inhibit beta-tubulin synthesis. Mode of action Systemic fungicide with protective and curative action. Absorbed through the roots and green tissues, with translocation acropetally. Acts by inhibiting development of the germ tubes, the formation of appressoria, and the growth of mycelia. Uses Control of Septoria, Fusarium, Erysiphe and Pseudocercosporella in cereals; Sclerotinia, Alternaria and Cylindrosporium in oilseed rape; Cercospora and Erysiphe in sugar beet; Uncinula and Botrytis in grapes; Cladosporium and Botrytis in tomatoes; Venturia and Podosphaera in pome fruit and Monilia and Sclerotinia in stone fruit. Application rates vary from 120-600 g/ha, depending on crop. A seed treatment (0.6-0.8 g/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 (0.3-0.5 g/l). Formulation types OP; SC; SL; WG; WP; Seed treatment. Compatibility Incompatible with alkaline materials.

Carbendazim ANALYSIS
Product analysis by titration against perchloric acid in acetic acid or by u.v. spectrophotometry. Residues in crops determined using methods for benomyl, hplc (J. J. Kirkland et al., J. Agric. Food Chem., 1973, 21, 368; Pestic. Anal. Man., 1979, II; J. E. Farrow et al., Analyst (London), 1977, 102, 752) or fluorimetry or colorimetry of derivatives (H. L. Pease & J. A. Gardiner, J. Agric. Food Chem., 1969, 17, 267; N. Aharonson & A. Ben-Aziz, J. Assoc. Off. Anal. Chem., 1973, 56, 1330).
