Description

A kind of Pesticidal combination containing spiral shell worm ethyl ester
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination containing spiral shell worm ethyl ester.
Background technology
Spiral shell worm ethyl ester (spirotetramat) chemical name: 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2,5-xylyl)-1-azaspiro [4, the 5]-last of the ten Heavenly stems-3-alkene-2-ketone, molecular formula: C 21h 27nO 5, new pesticides spiral shell worm ethyl ester is tetronic acid compounds, belongs to similar compound with insecticidal/acaricidal agent spiral shell mite ester (spirodiclofen) of Bayer company and Spiromesifen (spiromesifen).Spiral shell worm ethyl ester has unique function Characteristics, is the modern pesticides uniquely so far with two-way Uptake and translocation performance.This compound upwards can move down in whole plant corpus, arrives at blade face and bark, thus control is as on romaine lettuce and Chinese cabbage internal lobe, and the corticole insect of fruit.The interior absorption of this uniqueness can protect newborn stem, leaf and root, prevents ovum and the larval growth of insect.Its another feature is that the lasting period is long, can provide the effective control reaching 8 weeks.
Methoxyfenozide (methoxyfenozide); chemical name: the N-tert-butyl group-N'-(3-methyl-2-toluyl groups)-3; 5-dimethylbenzohydrazide; for the one of insect growth regulator, IGR; mainly the normal growth of interference insect is grown; even if insect molting and dead, and can suppress to ingest.This product water controlling object selectivity is strong, has special efficacy to lepidopterous larvae.
Worm hydrazides (tebufenozide), chemical name: 1-(1,1-dimethyl ethyl)-1-(4-ethylamino benzonitrile acyl group)-3,5 ,-dimethylbenzohydrazide, chemical molecular formula: C 22h 23n 2o 2, worm hydrazides is on-steroidal Novel insect growth regulator, is the insect hormone insecticides of up-to-date research and development.Tebufenozide pesticide activity is high, and selectivity is strong, and all effective to all lepidopterous larvaes, antagonism insect cotton bollworm, cabbage caterpillar, diamond-back moth, beet armyworm etc. have special efficacy.And have extremely strong ovicidal activity, safer to non-target organism.Worm hydrazides is to eyes and no skin irritation, to higher mammal without teratogenesis, carcinogenic, mutagenesis, all fool proof to mammal, birds, natural enemy.
In the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.Find through inventor's lot of experiments, after spiral shell worm ethyl ester and worm hydrazides, methoxyfenozide are composite, synergistic effect is remarkable, and Environmental compatibility is fabulous, considerably reduces pesticide usage amount.

The embodiment of the present invention is the method adopting 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 during test, is placed in beaker respectively for subsequent use.Adopt the method connecing worm after first soaking leaf, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid configured, naturally dry, put into insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination borer population used is 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 then 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, and calculate the value of often kind of medicament thus with method of least squares.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (with spiral shell worm ethyl ester for standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=spiral shell worm ethyl ester of M spiral shell worm ethyl estertI × the P of+active component B active component B
In formula: M is the mixture of different ratio;
P active component Bfor the ratio that active component B is shared in the composition;
P spiral shell worm ethyl esterfor the ratio that spiral shell worm ethyl ester is shared in the composition.
Note: active component B is arbitrary a kind of in worm hydrazides, methoxyfenozide.
Application Example two:
For examination insect: trialeurodes vaporariorum.
