Root-knot nematodes are very harmful:
Nematodes, also known as root-knot nematodes, are known to be vegetable-infested nematodes mainly include high arch root knot nematodes, peanut root knot nematodes (there are about 330 kinds of infested crops), northern root knot nematodes (about 550 kinds of infested crops), southern root knot nematodes, Java root knot nematodes and beet root knot nematodes, etc., which can damage more than 3,000 crops in 114 families.
Mainly harmful to the roots, pathogenic nematodes parasitize between the root bark and the middle column, so that the root tissue overgrows, resulting in the formation of rhizobia of different sizes.
Therefore, the root is nodular and enlarged, which is the main symptom of the disease. Most nodules occur on fine roots, and when the infection is severe, secondary nodules can appear, and a large number of small roots occur, so that the root system is coiled into clumps and forms a whisker root mass. Because the root system is damaged, affecting the normal function, making it difficult to transport water and nutrients, coupled with the rot of old mature rhizomas, the diseased root necrosis after ***
Difficulty in controlling nematodes:
1, the variety of reproduction speed is very fast: root knot nematode can be both sexual reproduction, can also be parthenogenetic reproduction, each egg sac has 300 ~ 800 eggs, a year can breed 5-10 generations, and generations overlap.
2, the egg survival is strong, not easy to kill: although a large number of chemical control agents kill the nematode adult, but the chemical agent can not kill the worm eggs, the eggs are only poisoned into the dormant period, in the appropriate temperature environment, and can resume growth, re-infect the harmful crops,.
3, the breeding environment expanded: there are many vegetables, orchards use unripe and complete organic fertilizer, especially chicken manure, containing a large number of nematode eggs, while greenhouses provide breeding places for nematodes.
4, the cultivation of varieties of resistance to the line is not strong: nematodes are harmful *** for the serious gourd family melon vegetable cucumber, watermelon, melon, loofah, bitter melon, etc., including grafted rootstock, there is no line resistance variety.
5, farmers have poor awareness of prevention and control: nematode disease focuses on prevention, not treatment. The initial symptoms of nematode disease are in the underground part, which is easily ignored by farmers, and when it is found, the symptoms are already more serious and it is difficult to prevent and control.
6. Chemical pesticides have developed resistance: the long-term use of chemical pesticides in the process of controlling root-knot nematodes has produced serious resistance and drug resistance. Because most of the nematode agents on the market are only paralyzing nematode nerves, and can not really kill nematodes, and Compson for the insect infestation characteristics and physical and chemical properties of insects, through the unremitting efforts of technicians, in a number of high-resistance areas of nematodes to repeatedly test, especially developed a plant essential oil product - perfect line, can completely and completely kill nematodes without rebound, there is no harm and residue to plants, is the ideal product for pollution-free vegetable planting.
Perfect Show Line - Compson
Essential oil of plants - nematodes
This product is a plant essential oil nematode preparation, the main ingredient is a variety of highland plant molecular extracts, after pressing distillation extraction of a variety of process combination or high-efficiency plant oil nematode preparation. With permeability, spreading and high adhesion, it mainly improves the soil environment through a variety of plant molecular extracts, breaks and changes the mechanism of action of the living environment of nematodes, and leads to nematodes that cannot adapt and die. This product is a plant extract that is environmentally friendly. In line with the development trend of green pollution-free.
