Basamid Granular1

Environmental Conditions

 The conversion of the active ingredient dazomet to methylisothiocyanate (MITC) in

Basamid Granular is dependent on several factors. Soil moisture and temperature are the

primary factors influencing this conversion. The recommendation for field preparation suggests

that soil moisture be at 50% of field capacity for 5 to 14 days prior to treatment of the soil. Soil

moisture enables the weed seeds to germinate, and therefore are more susceptible to the

treatment. Soil temperatures should be above 430 F at and during the time of treatment.

Optimum temperatures are between 54- 640 F. However, if temperatures fall below 43" F at

time of application, the gas may sink into the ground and may later diffuse back into the upper

soil profile after planting, and result in crop damage. If the temperatures are too high, the gas

may escape to the atmosphere prior to accumulation in the soil, thus reducing control.

 For increased control of nematodes, crop residues from prior plantings should be allowed

to decompose.


Methods of Application

 The application of Basamid Granular can be achieved by the use of (a) shaker, (b)

scoop, or (c) in larger areas, drop-type spreader. Immediately after application, it is important

to uniformly incorporate Basamid Granular into the soil. It is strongly recommended to seal the

surface which can be achieved in several ways (a) using a roller, (b) application of water to form

a crust, or (c) tarping the treated area. After 5 to 7 days, the soil can then be loosened with a
