Description
Technical field
The invention belongs to field of pesticide preparation, and in particular to be a kind of to contain Tolfenpyrad and emamectin benzoate benzene
The agricultural chemicals suspension agent of formates and its application.
Background technology
Suspending agent（Aqueous suspension concentrate, abbreviation SC）Refer to water-insoluble solid effectively into
Divide the sticky suspension formulation for forming high degree of dispersion in water with related auxiliaries, used after being diluted with water.Suspending agent is modern
In one of the highly important environment affinity type formulations of pesticide, generally with preferable bioactivity, and with preferably research and development before
Scape, at present, some of transnational agrochemical enterprise development relatively have feature and come into Chinese market and be widely recognized and make
Pesticide activity component, it is processed, and formulation is more based on suspending agent, and suspending agent turns into outside missible oil and wettable powder
Basic formulation, it is increasingly becoming the excellent formulation for substituting powderous preparations.As thermodynamic unstable system, the stability of suspending agent
Problem, especially long term physical stability problem, suppression are to influence the key of quality of the pharmaceutical preparations lifting.Therefore, it is necessary to for outstanding
Problem present in floating agent prescription development, production and use, so as to reach the purpose of General Promotion agricultural chemicals suspension agent quality.
Tolfenpyrad is former Mitsubishi chemical company（Its agricultural chemicals part now belongs to Japanese agricultural chemicals company）That develops is new
Pyrazole heterocycle class insecticidal/acaricidal agent, its main mechanism are to prevent the oxidative phosphorylation of insect, also with ovicidal, suppression
Food, suppress spawning and bactericidal action；Tolfenpyrad insecticidal spectrum is wide, to each Lepidopterous, Thysanoptera, coleoptera, Homoptera, dipteron
The insects such as mesh, Semiptera and snail class have special efficacy, especially have preferably to lepidopterous larvae diamondback moth, Thysanoptera thrips
Prevention effect, the medicament lasting period length, to insect whole breeding time, all there is higher activity, antagonism from ovum to adult
Insect is also effective.In addition, the medicament is also wide using crop scope, it can be applied to crops, vegetables, fruit tree, flowers, tealeaves
Etc. the control of insect of various crop.
Emamectin-benzoate be it is a kind of synthesized by tunning AVERMECTIN B1 it is efficient semi-synthetic anti-
Raw plain agricultural chemicals.Its ultra high efficiency, noresidue, pollution-free and hypotoxicity (and almost non-toxic preparation can be configured to).By first ammonia
The biological characteristics of base abamectin benzoate and other avermectin pesticides such as Ah bar's rhzomorph (abamectin), Doramectin
Plain (doramectin), ivermectin (ivermectin) are compared, its high 1-3 order of magnitude of insecticidal activity.It passes through
Stomach toxicity and contact poison provide the strong work of confrontation lepidopterous larvae (Lepidoptera pole larvae) and many other insects
Property.It has no adverse effects effectively and to beneficial insect under low-down dosage (0.084-2 grams/ha), and this causes it to be controlled to comprehensive
It is favourable for pest and disease damage processed.In addition, it expands insecticidal spectrum, and reduce the toxicity to people and animals.
In order to further develop new pesticide species and its stably, environmental protection preparation, present inventor is to Tolfenpyrad
Complex composition is carried out with AVM, and research is optimized to its formulation.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to providing one kind contains Tolfenpyrad and methylamino Avermectin
The water-based pesticide suspending agent of plain benzoate.
Another object of the present invention is to provide the application of the suspending agent, the suspending agent, which is particularly suitable for use in, prevents and treats fruit
The insect of tree, cotton, vegetables, flowers, gramineous crop etc., as tea lesser leafhopper, scale insect, pear sucker, planthopper, thrips,
Aphid, diamondback moth etc., especially, the suspending agent, which is particularly suitable for use in, prevents and treats tea lesser leafhopper.
In order to achieve the above object, the present invention adopts the following technical scheme that：
