Description
The application is divisional application; original application is the patent application " a kind of Pesticidal combination containing furan tebufenozide and carbamates " of Shaanxi Welch Crop Protection Co., Ltd.; the application number of original application is ︰ 201110135533.7, and original application day is 2011.05.26.
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination containing furan tebufenozide and carbamates.
Background technology
Furan tebufenozide is the insecticide that China has independent intellectual property right; chemical name: N-(2; 3-7-hydrogen-2; 7-dimethyl. benzofuran .6-formoxyl)-N '-tertiary butyl .N '. (3; 5 dimethylbenzoyls) hydrazine; furan tebufenozide, as the N-tertiary butyl bishydrazide compounds that contains benzofuran ring, has the moulting hormone regulating and controlling effect that bishydrazide compounds generally has.The Main Ingredients and Appearance of insect moulting hormones is steroid hormone 20-hydroxyl ecdysone, and this is peculiar a kind of somatotropin in arthropods body.In the time that 20-hydroxyl ecdysone concentration raises, larva enters the stage of casting off a skin, now larva stops feed, epidermal cell is recombinated, by combining closely with ecdysone receptor albumen, activated receptor albumen, the ecdysial fluid that contains multiple protein hydrolase enters the space of casting off a skin, it is synthetic that epidermal cell increases protein, generates new epicuticle and cuticula.In the time that 20-hydroxyl ecdysone concentration reduces, insect grows and enters next stage, comprises activation, the digestion of procuticle and the absorbing again of ecdysial fluid of enzyme in ecdysial fluid.Along with the further reduction of its concentration, complete needed other hormone of the process of casting off a skin and be released, insect recovers feed thereupon.
Indoxacarb (indoxacarb) chemical name: 7-is chloro-2,3,4a, 5-tetrahydrochysene-2-[methoxycarbonyl (4-Trifluoromethoxyphen-l) carbamoyl] indeno [1,2-e] [1,3,4-] oxadiazines-4a-carboxylate methyl ester, molecular formula: C

The embodiment of the present invention is the method that adopts Toxicity Determination and field trial to combine.First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is synergistic effect, on this basis, then carry out field trial.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration when test, is placed in respectively beaker for subsequent use.Adopt and first soak the method that connects worm after leaf, after the blade of the same size that does not contact any medicament is soaked to 5s in the liquid configuring, take out, naturally dry, put into insect box, then connect for examination larva, under 25 DEG C of conditions, raise, every processing repeats for 3 times, every to repeat examination borer population used be 50, establishes blank simultaneously, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50value.If contrast lethality is greater than 10%, be considered as invalid test.Computing formula is as follows:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates thus the value of every kind of medicament.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (taking furan tebufenozide as standard medicament, its toxicity index is 100):
TI × the P of theoretical toxicity index (TTI)=furan tebufenozide of M
furan tebufenozidetI × P of+effective active composition B
