New application of potassium formate for preventing and curing southern root knot nematode

Abstract

The invention provides new application of potassium formate for preventing and curing southern root knot nematode. The new application is that the potassium formate is used for preparing a southern root knot nematode pesticide; in the pesticide, the potassium formate can be taken as an active ingredient alone and can also be compatible with other ingredients for preventing and curing the southern root knot nematode together as an active ingredient. The pesticide is a potassium formate solution which is safe, non-toxic and efficient when used for preventing and curing the southern root knot nematode, and the egg incubation inhibition rate of the southern root knot nematode can reach 60%-90% or above when the concentration of the potassium formate solution is 4.00-10.00 mM / L; the second instar larvae fatality rate range of the southern root knot nematode is 10%-30% when the concentration of the potassium formate solution is 4.00-10.00 mM / L.

Description

technical field [0001] The invention relates to the field of antiparasitic drugs, in particular to the new application of potassium diformate for preventing and treating root-knot nematode incognita. Background technique [0002] Incognito root-knot nematode (Meloidogyne incognita) is one of the most important pathogenic organisms in the world, and it has brought serious economic losses to the world's agricultural production. Meloidogyne incognita has a wide host range, totaling more than 1700 plant species. Its life cycle length is mainly affected by temperature, humidity and host species. The soil temperature is 20-30°C, the relative humidity is 40%-70%, and the pH is 4-8, which is most conducive to the growth and reproduction of nematodes. Meloidogyne incognita only needs 30-60 days to complete a life cycle under normal temperature and humidity. In recent years, the rapid development of vegetable greenhouses in my country has provided a suitable temperature for the rep...
