For best results, apply Sil-MATRIX on a preventive schedule for disease control. Begin applications when environmental conditions are conducive to disease development. Repeat applications no sooner than every seven days. When conditions are ideal for rapid development of disease, it is recommended that Sil-MATRIX be used in a rotational program with other registered fungicides.

For mite and insect control, begin applications when pests first appear and repeat applications as necessary to maintain control (but no sooner than every seven days).

For best results, apply Sil-MATRIX before leaf hardening.

For maximum results, use a high analysis non-ionic surfactant at recommended label rates.

For fruit, nut, vine and vegetable crops, apply 0.5 to 1% solution (2-4 quarts Sil-MATRIX/100 gal.) in 50 to 250 gallons (vegetables, 20 gallons) of finished spray per acre.

Apply up to the day of harvest (0 day PHI).

Do not apply more than 10 quarts (vegetables, 4 quarts) per acre per application.
