Sugarcane has a new way to control pests.
First, it is mainly composed of 18% insect killer (Chongan) with high efficiency, low toxicity, low residue and low cost, together with broad-spectrum, low-toxic and long-acting bio-pesticide pesticides avermectin and Bacillus thuringiensis (Bt). Spray with 18% insect killer 300-400 ml per mu, add abesu 50 grams, add 45-60 kg of water; or use 18% insect killer 300-400 ml, add 1.8% avermectin 30-40 ml, spray 45-60 kg of water; use 18% insect killer 300-400 ml, add 0.5% carvedilate 30-40 g, spray 45-60 kg water per mu. Second, use the pesticide with a reasonable proportion. The mu is sprayed with 55% special killing borer 75-100 g, 45-60 kg of water, or 30% Awei (30% Awei) 120-160 ml, 45-60 kg of water. Third, farmers who like to use quick-acting and long-acting pesticides can choose Jingong 4% methylvitamin salt with 1000-1500 times high chlorine, or Centrino 4.2% methyl vitamin salt with 1200-1500 times high chlorine.

Control measures of sugarcane heart borer
Sugarcane heart borer is mainly sugarcane Chilo suppressalis and Chilo suppressalis. These two kinds of borers have 3-4 generations a year, the first generation generally occurs from the first and middle of May to the first and middle of June, and the second-third generation occurs from late June to September. Sugarcane will be damaged by these two kinds of borer from seedling stage to pre-harvest, among which the occurrence of the first-second generation is more harmful.

First, the characteristics of sugarcane fertilizer requirement. As far as a large number of elements are concerned, the fertilizer requirement of sugarcane is that the absorption of potassium is greater than that of nitrogen, and that of nitrogen is greater than that of phosphorus. Among them, nitrogen fertilizer should be applied less in the early stage, re-applied in the growing period, and applied appropriately in the later stage. Due to the concentration of phosphate fertilizer in the early growth stage of sugarcane, it has a great influence on the growth of hairy root and seedling, so it is suitable to be used as base fertilizer.
