1. Occurrence and harm
Sugarcane termites are important pests of sugarcane on wet and dry slopes in Yunnan. The Yunnan sugarcane areas mainly include black-winged soil termites and yellow-winged termites. The whole growing period of sugarcane can be endangered by termites, so that the most serious damage occurs after sowing. The harmful sugarcane species invade from both ends of the incision and feed the tissues in the stem so that the seedlings can not germinate. The new land is more serious than the victim. Severe sugarcane area hazard rate as high as 30% to 60%, resulting in a large area of ​​lack of seedlings off ridge, or even all lost; in the middle and later stages of the ingestion by the root cane, hollow stems, leaves yellow or dry shoots, the whole plant withered.
2. Control methods
(1) Deep ploughing and soil improvement before planting, destroying the ant nest, and destroying termites before sugarcane planting.
(2) When soaking the seed for 1 minute or 15% per acre, use 15% of Le Sibu granules 1 to 1.2 in a 300 to 400 times solution of 48% of Le Siben EC, 50% of phoxim EC, 5% of Ruijin EC, etc. Kg or 3% methyl isofluosaphos, 3% carbofuran, 5% butyl thiocarbamate and other granules 3 to 5 kg, and 40 kg of dry fine soil or chemical fertilizer mixed evenly in the planting cane trench cover, soil conservation time can be About 2 months.
(3) Using termites to eat plants such as pine twigs, twigs of twigs, sugarcane residues, etc. to set traps, when a large number of termites are trapped in the pits, chemical agents such as mirex, thosban, phoxim, etc. can be used to spray. .
