Description
Technical field
The invention belongs to technical field of pesticide, and in particular to the medicament and its system of a kind of killing underground injurious insect and Plant nematode
Preparation Method.
Background technology
Subterranean pest-insect refers to all one's life or some stage lives in harm foot end, seed, children in soil in life
The omnivorous insect of seedling or nearly native table stem, mainly there is the native stinkbug of mole cricket, grub, wireworm, cutworm, root maggot, root, root aphid and white
Ant etc..
At present, preventing and treating subterranean pest-insect is mainly by mixing the methods such as fertilizer, seed dressing, pouring root, mostly using organophosphors such as phoxims
Preparation.
Plant nematode can cause many important plant nematode diseases, such as soybean cyst nematode, peanut root-knot nematode
Disease, sweep stem nematode and aphelenchoides besseyi disease etc..The wound that the puncture of nematode is sucked and caused in tissue, has to plant
Certain influence, but nematode plant failure is acted on it is maximum be esophageal gland secretion, cell division can be stimulated into struma
With the deformity such as the excessive branch of root, the division for suppressing rhizome apical meristem cell, dissolving mesoglea make cell sepn and
Dissolve cell membrane and destruction cell.
At present, the chemicals of preventing and treating Plant nematode mainly has gram line pellet, fosthiazate etc..
Chinese patent CN201210205932.0 discloses a kind of simultaneous compound medicine for controlling subterranean pest-insect and plant pathogeny line insect
Agent, the medicament is compounded by cadusafos and chlopyrifos, phoxim etc., and the medicament can be prevented and treated simultaneously, prevention effect
Preferably；But usage amount is big, and substantial amounts of chemical agent can cause the accumulation in plant and residual, cause pollution by pesticides etc. to ask
Topic, as the important threat to health.
