Description
Technical field
The present invention relates to a kind of pesticidal preparations, be specifically related to the suspension agent composition that a kind of active ingredient comprises pyrrole aphid ketone
Background technology
For a long time, the peasant uses single medicament or non-science to use agricultural chemicals, causes the pesticide resistance of insect to strengthen year by year, and dosage also increases year by year, and is increasing to the harm of environment.
Pyrrole aphid ketone is that a kind of new and effective insecticide is the pyridine heterocycle insecticides, and efficient, low toxicity are environmentally friendly.This insecticide mode of action uniqueness is not knocked down activity, can not produce direct toxicity to insect, but in a single day insect touches this medicament, just stops to get food immediately.Even organic phosphor and carbamate insecticide have been produced resistance, pyrrole aphid ketone to sucking pest particularly aphid, trialeurodes vaporariorum, rice leafhopper still have unique control efficiency, can be used for the control of multiple resistant strain insect.Because of its high selectivity that has, to mammiferous hypotoxicity with to birds, fish, the arthropodan safety of non-target, in integrated control, demonstrate bright development prospect.But the disadvantage that this medicament exists is that quick-acting is poor, needs the long period after the dispenser, and insect is just dead.
In recent years, water baseization is the main direction of formulations of pesticide exploitation, suspending agent is one of most important formulation wherein, suspending agent is a kind of thermodynamic unstable system, as time passes, the variation of state can take place unavoidably finally, quality problems such as layering, the knot end appear, and the size of suspending agent particle diameter directly has influence on the quality of product, and particle diameter is big occurs quality problems such as layering, the knot end, suspensibility be low easily, thereby influences the performance of drug effect.At present general suspending agent 90% particle diameter is about 5 microns, and is even bigger.And the main factor that influences particle diameter is a surfactant, dispersant particularly, and dispersant does not choose, and particle diameter is difficult to levigate.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art,, provide a kind of particle diameter thinner, that suspensibility is higher, the hot storage suspension agent composition that contains pyrrole aphid ketone that performance is more stable, drug effect is better mainly by the selection of dispersant.
The present invention can be achieved through the following technical solutions:
A kind of suspension agent composition that contains pyrrole aphid ketone is characterized in that, this suspending agent content meter by weight comprises following component:
Pyrrole aphid ketone 5-30%
Active ingredient B 0.5-50%
Wetting agent 1-3%
Dispersant 2-5%
Antifreeze 3-6%
Defoamer 0.1-2%
Thickener 0.1-2%
Water supplies 100%
Described active ingredient B is any one in Mobucin, Nitenpyram, Imidacloprid, Avermectin, Buprofezin, thiophene worm quinoline, the Acetamiprid.
Described wetting agent can be selected one or more among the condensation product OP-10 of phenethyl phenol polyethenoxy ether, extraordinary polyether-modified polysiloxane, isopropyl naphthalene sodium sulfonate MorwetIP, alkyl phenol and oxirane for use.
Described dispersant can be selected one or more in MODIFIED LIGNOSULPHONATE, alkyl naphthalene sulfonic acid condensation product MorwetD-425, polycarboxylate Tersperse 2500, poly-naphthaldehyde sulfonate sodium, the sodium methylene bis-naphthalene sulfonate for use.
Described antifreeze can be selected one or more in ethylene glycol, propane diols, glycerine, the urea for use.
Described defoamer can be selected one or more in dimethyl silicone polymer, the isooctanol for use.
Described thickener can be selected one or more in gum Arabic, xanthans, sodium alginate, the aluminium-magnesium silicate for use.
The present invention is achieved the selection that depends on dispersant, and compared with prior art, the suspension agent composition that contains pyrrole aphid ketone of the present invention is that a kind of particle diameter is thinner, suspensibility is higher, the more stable suspension agent composition of heat storage performance.
