Description
Technical field
The invention belongs to the field of killing of river snail, particularly relate to the application of a kind of macleaya cordata infusion in killing river snail.
Background technology
River snail (Cipangopaludina chinensis Gray), be commonly called as spiral shell, Tanaka's spiral shell, Neptunea cumingi, Mollusca, Gastropoda, Mesogastropoda, Viviparidae, each freshwater of China all has distribution, moving in the silt in lake, river, marsh, pond and paddy field, creep on the bottom or water plants with roomy foot at ordinary times, is main foodstuff with leaf juice and the algae of water plants.Be distributed in Korea, North America etc. abroad.
River snail is because of delicious, fragrant, sharp and clear, good and cheap, and be rich in rich in protein, vitamin etc., be of high nutritive value, once be loved by the people, but because of blindness, a large amount of artificial feedings and mismanagement, river snail is diffused into the field rapidly, become a kind of new agriculture pest in some places, except that get the food rice shoot in the rice field, cause outside the rice underproduction, also get the food asparagus lettuce, Chinese cabbage, cowpea, kidney bean, cucumber, the seedling of vegetables such as a variety of Chinese cabbage, cause disconnected seedling to lack nest, also get the edible oil dish, corn, wheat, clover, broad bean, tender leaf of plants such as pea and true leaf cause production loss.As between 2007 7, August, only the paddy field in cross road mountain village, town, Yinhai District Pingyang, the North Sea, Guangxi has just suffered large-area river snail evil, and many rice roots have been gnawed disconnected lodging by river snail, and river snail hazard rice field area is about 300 mu.In recent years, along with the quick breeding of river snail, the harm that causes is increasing, and therefore being badly in need of a kind of effective and safe drug controls its harm.
The invertebrate poison of current use is divided into inorganic and organic invertebrate poison 2 classes by the material classification.The representative kind of inorganic invertebrate poison has copper sulphate and calcium arsenate, and is now inactive.Organic invertebrate poison has 10 kinds, is divided into following a few class by chemical constitution: 1. phenols, and as penta sodium pentachlorophenate (PCP-Na, sodium pentachlorophenol), niclosamide (clonitralide, hundred spiral shells kill, niclosamide), B-2.2. morpholine class is as trifenorph (trifenmorph, trifenmorph).3. organic tin is as Butinox (biomet, bis oxide tributyltin), fentin acetate (hundred spiral shells enemy).4. neires toxin is as thiocyclam (thiocyclam, SAN-155I, kill thiophene ring, first sulphur ring), desinsection fourth (sulphur cyclohexane monohydrochloride hydrochlorate).5. other, as the methaldehyde (metaldehyde, closely reach, Halizan, metaldehyde), methiocarb (methiocarb, non-irrigated spiral shell goes out), sulfuric acid nicotinanilide (nicotinanilidesulphate).What the last use of production at present was maximum is 3 organic invertebrate poisons such as niclosamide, the methaldehyde, methiocarb.Though it is fast that these chemosynthesis molluscicides kill the spiral shell time, can cause environmental pollution, also can cause poisoning to crop, causes residue of pesticide, therefore, necessary to work out a kind of killing effect good, and to the bio-pharmaceutical of crop and environmental nonpollution.
Since Archibald R.G in 1933 had reported the fruit that utilizes a kind of Oak Tree Balanites aegyptiace first and carries out snail killing test, people constantly sought the new spiral shell plant resources that goes out.Up to now, plant species is used to the activity against snails test surplus in the of approximately existing 1000, and filters out some mollusk is had strong toxic action and its procreation is had inhibiting plant.That studied both at home and abroad has the plant of killing effect to mainly contain Theaceae, Phytolaccaceae, Mimosaceae, polygonaceae, Verenaceae, Caesalpiniaceae, Euphorbiaceae to spiral shell, Theaceae oil tea wherein, its fruit is rich in Tea Saponin, good to the river snail killing effect, but it is big to fish and other non-target bio-toxicity, thereby has limited development and the application of these plants.
