In 1999, a 4.8 ha block of seedcane (var 1547) in Port Mayaca, FL was divided into 2 sections of 2.4 ha. The west side received one application of SUL-15 PLUS by air. The rate was 2 kg in 20 litres of water. Application was 5 days prior to cutting.
Treated cane was sprayed January 8th, cut January 12th and planted on January 14th, 1999. Untreated cane was cut January 12th and planted January 12th and 13th 1999.
Plant biomasses from treated and untreated sections were sampled on March 4th 1999 (Seven weeks after planting). Three 1.5 m by 3 m row cross sections of the field were tested in the south, middle and north portion of the field. All vegetation was cut down to the soil, counted, collected and weighed. A total of 60 rows were sampled.

The first application of 2.5 kg SUL-15 PLUS per hectare should be made at 6-8 weeks roughly from cutting - when the cane starts to grow vigorously; a follow up application of 2.5 kg per ha should be made after 6 weeks. It is recommended that at least 2 applications be applied.
SUL -15 PLUS on SUGAR CANE
In 1998 some 15 hectares of First Stubble, Variety 384 (regular planting) sugar cane were divided into 12 equal plots; 6 were treated and 6 remained untreated. All the plots had same basic soil conditions, production history and fertilizer programme. All treated and untreated plots were planted at the same time. The treated fields received aerial applications of 2.5 kg SUL-15 PLUS per hectare on the 20th June '98 and again on 27th July '98.
Treated plots produced significantly greater yields of sugar per hectare compared to untreated.

An increase of 1.26 tes sugar per ha @ $0.474/kg = $597 per ha.
$597 x 61% = $364.17 per hectare gross to grower.
$364.17 x 80% = $291.34 per hectare net to grower.
Product cost + cost of application @ $60/hectare $291.34 net profit per hectare ÷ $60/ha cost = 485% rate of return.
