3. Improve insecticidal activity
Chitosan oligosaccharide has certain insecticidal activity towards Lepidoptera and Homoptera pests. The insecticidal activity to diamond back moth is higher than cotton bollworm. The insecticidal activity to different aphids is ranged from 60%~80%, utmost 99%.
4. Promote root growth
After application, root developed, increased the number of secondary roots, root hairs, fibrous roots. developed rhizosphere will enhance the absorption of fertilizer and water.
Enhance drought, lodging resistance, enhance immunity.
5. Improve crops quality,increase yield
Chitosan oligosaccharide can improve crop quality, increase yield, return crops’ natural taste, easy for storage and transportation, also reduce pesticide residue.
6. Be compounded to foliar fertilization
Mix Chitosan oligosaccharide with fertilizer, micro trace element and antiseptic etc., then dressing seed, it can promote rape growth, increase sound seedling rate, increase yield by 4.3%~9.7%
