Problems solved by technology

However, the chemical nematicides currently used have many problems such as high toxicity and serious environmental pollution.
The application of chemical nematicides is increasingly limited with the increasing public awareness of environmental protection and the increase of nematode resistance
There is no report on the control of root-knot nematode incognita

Embodiment 1

[0022] Embodiment 1 Different concentrations of calcium formate solution are to the influence of incognita incognita (Meloidogyne incognita) egg hatch inhibition rate

[0023] 1. Materials: Calcium formate is made into solutions with concentrations of 0.50mM, 1.00mM, 2.00mM, 4.00mM, 8.00mM and 10.00mM, and neutralized with potassium hydroxide to obtain 0.50mM calcium formate solution (insecticide 1 ), 1.00mM calcium formate solution (insecticide 2), 2.00mM calcium formate solution (insecticide 3), 4.00mM calcium formate solution (insecticide 4), 8.00mM calcium formate solution (insecticide 5) and 10.00 mM calcium formate solution (insecticide 6). Store in -20°C refrigerator for later use.

Abstract

The present invention provides new uses of calcium formate in prevention and control of Meloidogyne incognita, particularly new uses of calcium formate in preparation of a Meloidogyne incognita insecticide, wherein calcium formate can be separately used as an active component, and can further be compatible with other active components capable of preventing and controlling Meloidogyne incognita so as to be co-used as an active component, the Meloidogyne incognita insecticide is a calcium formate solution, the advantages of safety, no toxicity and effectiveness can be provided by using the calcium formate solution to prevent and control Meloidogyne incognita, the Meloidogyne incognita egg hatching inhibition rate can achieve 90% when the concentration of the calcium formate solution is 8.00-10.00 mM / L, and the Meloidogyne incognita second instar larva fatality rate is 30-40% when the concentration of the calcium formate solution is 8.00-10.00 mM / L.

Description

technical field [0001] The invention relates to the field of antiparasitic drugs, in particular to the new application of calcium formate for preventing and treating root-knot nematode incognita. Background technique [0002] Nematodes (Nematodes) are a class of low-level invertebrates with a wide variety, some live freely in oceans, lakes, rivers / swamps, some live in soil, some parasitize humans and animals, and some parasitic in plants. Plant parasitic nematodes are called plant parasitic nematodes. At present, there are more than 90 kinds of root-knot nematodes reported in the world, and Meloidogyne incognita, Meloidogyne javanica, Meloidogyne arenaria and Meloidogyne hapla It accounts for 95% of the whole root-knot nematodes, among which root-knot nematode incognita and root-knot nematode javana are more common. Meloidogyne incognita J2 larvae have the ability to infect plants, they sense the signal molecules of the host secretion in the soil, and migrate towards the ...
