Description
Technical field
The invention belongs to field of pesticide preparation, specifically design a kind of chrysomelid insecticide of rice root.
Background technique
Rice root is chrysomelid also known as rice root leaf beetle, in Guangdong some areas occurring and damage rice.Larva concentrates on rice root
Fibrous root is bitten, is killed rice strain slow growth, roots blacking, the jaundice of rice leaf, effective tillering and fringe grain substantially reduce, full when serious
Strain is withered, and the strain of aggrieved rice, which is gently pulled out, to be risen, while can find a large amount of larvas and pupa invests on rice root.Rice root is chrysomelid except rice of causing harm
Outside, also can a variety of water plants such as feeding barnyard grass, trip grass, lotus, the rhizoma alismatis that comes into leaves, short arrowhead, Monochoria vaginalis and bog pondweed, wherein bog pondweed
Even more its important wild host.
Present invention discover that xanthoxlin has the anti-chrysomelid effect of rice root, and combined with the methaldehyde, it is chrysomelid that anti-rice root can be enhanced
Effect, pollution-free, green pesticide.
Summary of the invention
The present invention is intended to provide a kind of green, the free of contamination chrysomelid insecticide of rice root.
For achieving the above object, a kind of chrysomelid insecticide of rice root of the present invention, the specific scheme is that
A kind of chrysomelid insecticide of rice root of the present invention, active constituent are made of xanthoxlin and the methaldehyde, and xanthoxlin and four gathers
The mass ratio of acetaldehyde is 0.02: 1-5: 1.
A kind of chrysomelid insecticide of rice root of the present invention, the suitable dosage form have emulsion, wettable powder, water-dispersible grain
Agent, suspension, oil-suspending agent, ultra low volume liquids, electrostatic oil agent or dry suspensoid agent, carrier.
A kind of chrysomelid insecticide of rice root of the present invention, the dosage form are dry suspensoid agent.
A kind of chrysomelid insecticide of rice root of the present invention, the dry suspensoid agent formulation weight percentages are as follows: xanthoxlin 10-
40%, methaldehyde 10-35%, suspending agent 1-50%, adhesive 1-30%, wetting agent 1-10%, lubricant 1-10%.
A kind of chrysomelid insecticide of rice root of the present invention, the dry suspensoid agent formulation weight percentages are as follows: xanthoxlin 15-
30%, methaldehyde 15-30%, suspending agent 10-30%, adhesive 10-30%, wetting agent 1-10%, lubricant 1-10%.
A kind of chrysomelid insecticide of rice root of the present invention, the dry suspensoid agent formulation weight percentages are as follows: xanthoxlin
25%, the methaldehyde 15%, suspending agent 25%, adhesive 20%, wetting agent 10%, lubricant 5%.
A kind of chrysomelid insecticide of rice root of the present invention, the dry suspensoid agent preparation process: by the xanthoxlin of recipe quantity and
The methaldehyde, suspending agent, adhesive be uniformly mixed, add suitable wetting agent and mix lubricant uniformly to get.
A kind of chrysomelid insecticide of rice root of the present invention, the suspending agent are hydroxypropyl methyl cellulose, carboxymethyl cellulose
The one or more combinations of plain sodium, Arabic gum, sodium alginate, xanthan gum；Described adhesive is starch, lactose, mannitol one kind
Or multiple combinations；The wetting agent is glycerol, propylene glycol, the one or more combinations of polyethylene glycol.
A kind of chrysomelid insecticide of rice root of the chrysomelid insecticide preparation method preparation of rice root of the present invention.
Application of the chrysomelid insecticide of rice root of the present invention in prevention and treatment rice root is chrysomelid；Specially xanthoxlin and the methaldehyde
Application of the composition in prevention and treatment rice root is chrysomelid.
The advantages and beneficial effects of the present invention are:
(1) it is undesirable to overcome single formulation effect due to using xanthoxlin and methaldehyde compound formulation for product of the present invention
Disadvantage combines two kinds of drugs of xanthoxlin and the methaldehyde, has apparent synergistic effect, to pests such as rice root class Diabroticas
Toxicity is stronger, can greatly improve insecticidal effect, significant to shorten onset time.
(2) xanthoxlin and the methaldehyde are prepared into dry suspensoid agent, it is more stable, it is more convenient transport, is converted when implementing desinsection
The soluble easy dispersion of water.
(3) xanthoxlin, methaldehyde low toxicity, environmentally protective, not containing benezene, in the production and use process to operator and
Environmental security.
