Ointment for preventing and treating forestry pest aspen longhorn beetles

Abstract

The invention belongs to the field of pesticides and preparations of pesticides, and particularly relates to an ointment for preventing and treating forestry pest aspen longhorn beetles.The ointment is prepared by mixing, by weight, 10-45% of methylamino abamectin benzoate, 0.5-15% of 24-member-ring contraction phenolphthalein, 2-10% of a cosolvent, 5-10% of an adhesive and the balance powder filler.The ointment has the advantages that the effective ingredients, namely methylamino abamectin benzoate and 24-member-ring contraction phenolphthalein, of the ointment have high toxicity and have an obvious toxicity enhancing effect after being mixed at a specific proportion; the effective ingredients methylamino abamectin benzoate and 24-member-ring contraction phenolphthalein have the advantages of being highly toxic to aspen longhorn beetles and low in toxicity or nontoxic to human and livestock, and thus the harm to human, livestock and the natural environment is smaller than that of traditional high-toxicity zinc phosphide or organic phosphorous when the ointment is used in a large scale; the ointment is easy to prepare and can be prepared as long as al the raw materials are mixed evenly according to the specified weight proportions.

Description

technical field [0001] The invention belongs to the field of pesticides and preparations thereof, and in particular relates to an ointment for preventing and controlling forestry pests poplar longhorn beetle. Background technique [0002] Poplar longhorn beetle is a general term for the insects of the family Beetleidae that seriously damage poplar such as the bald beetle, the yellow-spotted longhorn beetle, the mulberry beetle and the cloud-spotted beetle. There are more than 100 kinds of poplar longhorn beetles that have been reported in my country so far. Poplar is the main afforestation species of broad-leaved trees in my country. It is mainly distributed in roads, river embankments, farmland forest networks and surrounding village forests. Most of them are large-scale artificial pure forests. Due to factors such as single tree species, large pure forest area and single biological community, It not only provides rich food for the poplar long beetle, so that its number can ...

Problems solved by technology

[0005] The above various control methods all have their advantages and disadvantages. Among them, the disadvantages of the commonly used chemical measures are that most of the highly toxic pesticides used contain zinc phosphide or organic phosphorus substances. Although the effect of poisoning longhorns is better, But also have great harm to human body and natural environment, should not be used on a large scale; In addition, the highly toxic pesticides used at present contain volatile organic solvents more, or in order to pursue the active ingredient of good fumigation effect pesticide itself has extremely strong volatilization ( Such as dichlorvos), the consequences of which are that after the solvent volatilizes, the pesticide cannot be conducted in the tree or the active ingredient of the pesticide volatilizes rapidly, resulting in short-term efficacy and poor killing effect
