Abstract

A kind of compounding process of pesticide for scale insects is with polysulfide, resin soap and oil emu 1: 1 by volume: the proportioning of 0.1-10, in stainless steel or enamel container made, mix, and add the flolimat of 5-15% (volume ratio) again.Be the spray solution of 0.5-10% with agent material dilution for concentration when using.After using this agent 1-2 hour, kill ratio can reach more than 90%, and the residual quantity on the plant is below 1 ‰.

Description

Compounding process of pesticide for scale insects

The present invention relates to plant and use insecticide.

The people is known, and the mustard shell worm kind of occurring in nature is a lot, and they are very strong for the harmfulness of plants such as some crops, flowers, fruit tree, gently then makes plant withered, and the rotten and underproduction is heavy then cause plant death.In the prior art; someone adopts common agricultural chemicals (as flolimat, furans pellet etc.) spraying, mobile jib injection or root to bury method control mustard shell insect pests such as medicine; but effect is all undesirable; because said method is only obvious to mustard shell worm incubation period effect, yet their incubation period is extremely lacked (only 1-2 days); people are difficult to grasp; incubation period one mistake, the back of mustard shell worm can grow a kind of cured shell, and this cured shell can be protected polypide.At present, also there is not a kind of cured shell of mustard shell worm that can destroy effectively to reach the medicament of eliminating mustard shell worm purpose both at home and abroad.

The objective of the invention is to provide a kind of and can effectively destroy the cured shell of mustard shell worm at above-mentioned situation, thus the medicament that kills mustard shell worm.

This pesticide for scale insects is by polysulfide, resin soap and oil emu 1: 1 by volume: the proportioning of 0.1-10, in stainless steel or enamel container made, mix, yet, will add flolimat in the mixture, adding proportion (by volume) is: mixture: flolimat=1: 5-15%.Detailed process flow figure is as shown in drawings:

The concrete synthesis technique of its polysulfide is: solubility alkalescence oxide and sulfur content are mixed with water at the elemental sulfur more than 98%, in stainless steel or enamel reaction still, concentrate, its ratio (by weight) is: basic anhydride: elemental sulfur: water=1: 25: 10-15, its thickening temperature is 80～100 ℃, its concentration time is the 50-120 branch, and the concentration of concentrate reaches 20-30 ° of Be.

The synthesis technique of its resin soap is: will contain alkaline solution that fatty acid that carbon number is 10-20 and concentration is 5-20% and heat 50-105 ℃ and concentrate, the time is 10-30 minute, and being concentrated into concentration is 10-25 ° of Be.

The synthesis technique of its oil emu is: select that to contain carbon number be the fluid oil of 22-44 and to contain carbon number be that the saturated of 10-22 or unsaturated fat salt add water and carries out emulsification for use, this fluid oil fat salt: water (by weight)=1: 0.1-0.5: 1-3, emulsifying temperature is 60-90 ℃, the time with whole emulsifications till.

The method of using this pesticide for scale insects is with the spray solution of agent material dilute with water as concentration 0.5-10%, biweekly can reach the effect of killing more than 90%, and the residual quantity on the plant is below 1%.Trample observation factually, spray this agent 1-2 hour after, the cured shell of mustard shell worm begins dissolving, progressively attenuation is pulled open, and exposes behind the shinny polypide dead.Use this insecticide not to be subjected to time restriction, find that at any time insect pest can use at any time, it also has certain preventive and therapeutic effect to other common germ property insect pest, and its natural enemy is then murdered not quite, and this medicament technology is simple, and is easily synthetic, with low cost.

Claims
