Molluscicide

Abstract

The invention provides a molluscicide. The molluscicide takes an iron phosphate chelate as an effective component, the iron phosphate chelate is formed by chelating iron phosphate and a chelating agent, and the chelating agent comprises one or a combination of more than two of L-glutamic acid-N,N- tetrasodium diacid, methylglycine diacetic acid and tetrasodium iminodisuccinate. According to the invention, a novel molluscicide is created by chelating a natural substance iron phosphate existing in the nature with a biological strong chelating agent GLDA and the like, and the solubility of iron phosphate in soil is improved through the complexing action of the chelating agent, so that iron phosphate is absorbed by crops as a phosphate fertilizer, the problem of degradation residue of iron phosphate in soil is solved, and nutrients are provided for crops. The molluscicide is ensured to be harmless to the ecological environment and safe, and the problems that most molluscicide products arepoisonous and harmful to aquatic organisms such as fishes and wild animals, high in residue, poor in soil degradation and the like and cause ecological pollution to the environment are solved.

Description

technical field [0001] The invention relates to a molluscicide and belongs to the technical field of pesticides. Background technique [0002] The molluscs that harm crops mainly include snails (commonly known as buffaloes, dry snails), slugs, field snails (commonly known as snails), apple snails and snails. [0003] The occurrence of molluscs is large. The snails are hermaphrodites. They can lay eggs up to 300 at a time, and 300-2000 eggs a year; the apple snails are dioecious, and each female snail can lay eggs at a time. It can mature and reproduce, and can appear in the field. Snails and snails are greedy eaters, and bite young shoots, young leaves, and tender stems of crops, and can cause a large number of wounds on roots, stems, and leaves, which is conducive to the invasion of pathogenic bacteria such as fungi, bacteria, and viruses, and aggravates the damage to crops. [0004] Molluscs are widely distributed in humid and warm regions of the world, seriously endange...

But sodium pentachlorophenate has the irritating odor of unpleasant stench, can irritate skin, eyes, cause injury, threaten the health of human body

After sodium pentachlorophenate enters the soil, it will remain in the soil, which will affect the growth of subsequent crops, cause poor growth of subsequent crops, and infiltrate into groundwater, polluting groundwater sources
