Question

sugar cane leaf hopper can be effectively controlled by the use of?​

Answer 1

Answer:

Host plants / species affected

Carex (sedges)

Coffea arabica (arabica coffee)

Oryza sativa (rice)

Paspalum

Saccharum officinarum (sugarcane)

Zea mays (maize)

List of symptoms/signs

Leaves  -  internal feeding

Whole plant  -  distortion; rosetting

Whole plant  -  dwarfing

Symptoms

Direct damage by P. saccharicida includes laceration of tissue by the ovipositor and feeding damage by the nymphs and adults. This damaged tissue is then often infected by red-hot fungus (Glomerella tucumanensis), a condition described as 'hopper-burn'.

P. saccharicida is a vector for sugarcane Fiji disease fijivirus and the symptoms of this virus disease can be found in the corresponding data sheet. The distribution and description of insect vectors of sugarcane Fiji disease fijivirus have been reported (Antoine, 1967; Pemberton, 1935; Pemberton and Charpentier, 1969; Hutchinson and Francki, 1973).

Answer 2

Answer:

There have been reports of more than 1,500 species of insect pests feeding on sugar cane. Sugarcane insect pest control measures are based primarily on IPM programs. Developing P. saccharicida programs may combine different control strategies to suppress this pest's population. Cultural methods, biological control, host plant resistance, and chemical control are the strategies included. Early planting, fertilizer application and cleaning of wilted sheaths of sugarcane are introduced in China. Burning mature canes in Malaysia can decrease the population of insects before and after harvesting. Fiji disease control is currently based on techniques other than vector control. Methods include harvesting and burning, using resistant varieties, rouging seed cane, using virus-free seed cane and not planting near infected fields.
