The abamectin.indoxacarb suspending agent has the advantages that the abamectin. indoxacarb suspending agent disclosed by the invention is lasting in drug effect and wide in insecticidal spectrum, the primary pharmacy gets twofold results with half the effort, the main treatment object refers to rice leaf folder, and multiple injurious insects such as striped rice borer, tryporyza incertulas, pink rice borer and plant hopper are simultaneously treated; the pesticide formulation adopts an environment-friendly suspending agent dosage form, the low-toxicity standard is met according to detection, and adverse effects on the body health of users and natural environment are avoided; and moreover, the preparation method of the pesticide formulation is simple and feasible, the cost per mu is low, and the suspending agent is popularized and used in the agriculture.
Description
Technical field
The present invention relates to a kind of insecticide, particularly relate to a kind of Avermectin indoxacarb suspending agent, belong to pesticide field.
Background technology
Rice leaf roller is one of the primary pest in rice in China producing region, is distributed widely in Ge Dao district; Except causing harm except paddy rice, it also can take food the weeds such as the crops such as barley, wheat, sugarcane, grain and barnyard grass, Leersia Sw, ditch millet, Paspalum distichum, lady's-grass, green foxtail, yard grass, cogongrass, reed.Meanwhile, striped rice borer, paddy stem borer, pink rice borer, plant hopper etc. are also the common insects in field.
At present, the pesticidal preparations of the insects such as control rice leaf roller is of a great variety, such as single dose Avermectin or single dose indoxacarb etc.; Wherein, single dose Avermectin high temperature easily decomposes, the lasting period is short, anti-heterodyne, and alone indoxacarb cost price is high, and a kind of single dose agricultural chemicals of Long-Time Service easily produces resistance, thus loses its drug effect value.In order to effectively and quickly prevent and treat, eliminate pest, it is composite that someone proposes that agricultural chemicals is carried out combination by active ingredient, such as make preparation with Avermectin formulation and indoxacarb agent for active ingredient is composite, but still there is following problem: the first, complex agent type is mostly missible oil type, a large amount of hazardous solvent is employed in missible oil, can have a negative impact to the health of natural environment and user, the needs of agricultural production can not be met simultaneously; The second, for the Recompounded pesticide of suspending agent (environmental protection formulation), the composition of its auxiliary agent and not good with active ingredient proportioning, so drug effect is also not satisfactory.
Therefore, above-mentioned technical barrier urgently to be resolved hurrily.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of strong drug action, residual low, saving of work and time, meet the Avermectin indoxacarb suspending agent of national environmental protection formulation especially.
Technical scheme: Avermectin indoxacarb suspending agent of the present invention, comprises following component: active ingredient by weight percentage: Avermectin 0.1-30% and indoxacarb 0.1-50%; Auxiliary agent: wetting dispersing agent 0.5-10%, thickener 0.1-6%, stabilizing agent 0.5-10%, antifreezing agent 1-10%, preservative 0.1-5%, surplus is water.
Wherein, the percentage by weight of described Avermectin is 1-25%, and the percentage by weight of indoxacarb is 0.5-45%.
Preferably, the percentage by weight of Avermectin is 1-20%, and the percentage by weight of indoxacarb is 1-20%.Further, the percentage by weight sum of Avermectin and indoxacarb is 25-50%.
Meanwhile, Avermectin and indoxacarb weight proportion are 1:0.5-2.
Described wetting dispersing agent is triphenoethyl benzene phenol polyethenoxy polyoxypropylene phosphate amine salt.
Described thickener is any one in xanthans, Magnesiumaluminumsilicate, gum Arabic, CMC, PVA, polyacrylic acid, polyvinyl pyrrolidone.
Described stabilizing agent is dolomol.
Described antifreezing agent is propane diols or ethylene glycol.
Described preservative is Kathon CG or Sodium Benzoate.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: first, Avermectin indoxacarb suspending agent lasting medicine of the present invention, insecticidal spectrum are wide, a drug gets twice the result with half the effort, cure mainly to as if rice leaf roller, simultaneously doublely control the various pests such as striped rice borer paddy stem borer, pink rice borer, plant hopper; Secondly, this pesticidal chemical adopts the suspending agent formulation of environmental protection, meets " low toxicity " standard after testing, can not cause harmful effect to the healthy of user and natural environment; 3rd, the preparation method of this pesticidal chemical is simple, and mu cost is low, is conducive to agriculturally applying.

With reference to " farm-chemical indoor determination test rule insecticide the 14th part: leaf dipping method " (NY/T1154.14-2008) and " farm-chemical indoor determination test rule insecticide the 7th part: the synergy mensuration of mixture " (NY/T1154.7-2006) assay method, carry out Avermectin and each proportioning of indoxacarb mixture to the toxicity test of rice leaf roller.
Electronic balance takes Avermectin, indoxacarb, Avermectin and indoxacarb each combo respectively, first uses acetone solution, then become 5 series concentration with the distilled water diluting being added with a small amount of surfactant (0.05% Tween-80).Choose fresh light green rice leaf, be cut into the leaf section that length is 5cm, manage in concentration liquid throughout and flood 30s, taking out dries in the culture dish being placed on and being lined with moisturizing filter paper, each culture dish accesses 10 rice leaf roller 3 instar larvaes, repeat 4 times, be treated to blank with the distilled water being added with a small amount of surfactant (0.05% Tween-80).Each process is placed on temperature 26 ± 1 DEG C, relative moisture 75%, raises under periodicity of illumination L:D=16h:8h condition, after process, 48h investigation examination worm death condition, calculates lethality.
4 data surveys and statistical analysis
4.1 investigation methods and grade scale
Investigation examination worm death condition, records total borer population and death toll.Worm alive and dead worm criterion touch polypide with writing brush, and examination worm can not the coordinated movement of various economic factors be death standard.
4.2 control times and number of times
After the process of examination worm, 48h investigates total borer population and dead borer population, investigates 1 time.
4.3 data statistic analysis
According to survey data, calculate the corrected mortality of each process, analyze by data handling system (DPS), calculate the LC of each medicament
50, b value, standard error and 95% confidence limit.And the co-toxicity coefficient (CTC value) of mixture is calculated according to the abundant method of Sun Yun.Result is see table 5.
The co-toxicity coefficient (CTC) >=120 of built agent shows as synergistic effect; CTC≤80 show as antagonism; 80 < CTC < 120 show as summation action.
Table 5 Avermectin and indoxacarb different ratio are to the toxicity test result of rice leaf roller
5 interpretations of result
As shown in Table 5, Avermectin, indoxacarb have higher virulence active to rice leaf roller, its LC
50be respectively 0.3921mg/L, 0.1408mg/L.Avermectin and indoxacarb are with 1:1, 2:3, 1:2, 2:1, the LC50 of 5 proportionings of 3:2 ratio mixture is 0.0988-0.1452mg/L, co-toxicity coefficient CTC is respectively 169.14, 191.64, 182.96, 160.03, 166.14, illustrate that Avermectin and indoxacarb mixture have higher virulence to rice leaf roller active, and have obvious synergistic effect, wherein with 2:3, the ratio mixed synergies of 1:2 is remarkable, simultaneously, we rationally can infer that Avermectin and indoxacarb weight proportion are that 1:0.5-2 all has higher virulence activity to rice leaf roller and other similar disease.
