Abstract
A synergistic composite insecticide for preventing and treating rice borer and beet noctuid contains iurfenuron, chlorpyrifos, assistant and excipient.
Description
Technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, especially a kind of is the Pesticidal combination and the application thereof of main active with Acarus tritici urea and chlopyrifos.
Background technology
Acarus tritici urea (Lufenuron), chemical name: N-[[[2,5-two chloro-4-(1,1,2,3,3,3-hexafluoro third oxygen) phenyl] amino] carboxyl]-2, the 6-difluorobenzamide.Be by the exploitation of Switzerland Syngenta Co.,Ltd, CAS:103055-07-8, its 5% missible oil commodity U.S.A by name removes.
The Acarus tritici urea belongs to benzoyl area kind and kills mite, insecticide, and a kind of insect growth regulator, IGR is a chitin synthesis inhibitor.Be mainly used in control beet armyworm, prodenia litura, tomato moth, diamond-back moth, cotton bollworm, lima bean pod borer, melon thin,tough silk snout moth's larva, oriental tobacco budworm, thrips, rust mite, citrus leaf-miner, plant hopper etc.Tool stomach toxicity and action of contace poison, the unique insecticidal mechanism of tool: suppress insect decortication, desinsection, to kill ovum effective, insect has eaten and has sprayed the crop that U.S.A removes and stopped to get food in 2 hours, enters dead worm peak in 2-3 days.Be characterized in 1. low toxicity, suitable non-polluted farm product production.2. desinsection kills ovum, kills large and small larva, 14 days lasting periods.3. permeability is strong, positive spray medicine, the dead worm in the back side, dead ovum.4. anti-rain washes away, and spraying rains after back 15 minutes does not influence drug effect.
In China, because Acarus tritici urea import price height, usable floor area is confined on the high part fruit and vegetables of economic value added, the application area is less, can not in the crop pests control, use widely, and the Acarus tritici urea is not seen the control of insect that field crops such as being used in paddy rice, wheat is arranged in the document at home and abroad.
Chlopyrifos belongs to neurovirulent fast-acting insecticide, and most of lepidoptera pest is had higher preventive effect, and is that toxicity is low, insecticidal spectrum is wide, have tag, stomach toxicity and fumigation action, the agricultural chemicals that has also has acaricidal action.It is the reasonable substitute of high malicious organophosphorous pesticide.But the organic phosphorous insecticide lasting period is short, and on the low side to the lepidopterous larvae insecticidal activity more than 2 ages.Thereby use single agent kind all can not reach best pest controling effect separately.
Lepidoptera pest as cabbage caterpillar, cotton bollworm, aphid, beet armyworm, the snout moth's larva of rice etc., increases gradually in present resistance, and the agent of agricultural chemicals list descends gradually to the effect of control of insect, and agriculture chemical compounding can obviously improve drug effect, and delays the generation of pest resistance.Still find no up to now and close Acarus tritici urea and organic phosphorous insecticide Pesticidal combination.
Summary of the invention
The purpose of this invention is to provide that a kind of what prevent and treat Lepidoptera, Homoptera and Acarina is the Pesticidal combination and the application thereof of main active with Acarus tritici urea and chlopyrifos.
Technical scheme of the present invention is:
A kind of Synergistic insecticidal compositions that contains Acarus tritici urea and chlopyrifos, it is characterized in that with Acarus tritici urea and chlopyrifos be the primary activity composition, auxiliary agent and the composite composition of excipients in addition, wherein the weight portion of each component is: 0.1～10 part of Acarus tritici urea, 5～50 parts of chlopyrifos, 3～10 parts of auxiliary agents, surplus are excipients.
Described auxiliary agent is the one or more combinations in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound or the polyoxyethylene nonylphenol ether, and excipients is dimethylbenzene or solvent naphtha or its combination.
The Synergistic insecticidal compositions that contains Acarus tritici urea and chlopyrifos of the present invention is that effective ingredient is present in the composition with the synergy effective dose.
Optimum weight part of Acarus tritici urea in the Synergistic insecticidal compositions that contains Acarus tritici urea and chlopyrifos of the present invention is 0.5～5 part, 10～40 parts of optimum weight parts of chlopyrifos.
Pesticidal combination of the present invention can be used for preventing and treating Lepidoptera, Homoptera, acarina pest.
Pesticidal combination of the present invention can be used for preventing and treating the snout moth's larva of rice and beet armyworm.
Beneficial effect of the present invention:
Pesticidal combination of the present invention compared with prior art produces following beneficial effect: (1) is compared with single agent, and said composition has notable synergistic to lepidoptera pest, has obviously improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (3) alternative high-toxic pesticide, and reduce the field dosage significantly, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the agent of Acarus tritici urea list, produce and the use cost reduction; (6) suppress the resistance enhancing of lepidoptera pest to agricultural chemicals; (7) reduction is to the toxicity of warm blooded animal.(8) especially can be used for preventing and treating the present serious snout moth's larva of rice of taking place at home: rice leaf roller, striped rice borer, paddy stem borer.
Embodiment
The present invention is further illustrated below in conjunction with embodiment.
Embodiments of the invention are the methods that adopt indoor bioassay and field trial to combine.Pass through indoor bioassay, the co-toxicity coefficient after clear and definite two kinds of medicaments are composite by a certain percentage earlier; On this basis, carry out field trial again.
Embodiment 1:
Take by weighing Acarus tritici urea 2 gram, chlopyrifos 30 grams, calcium dodecyl benzene sulfonate 5 grams, phenethyl phenol polyethenoxy ether 2 grams, surplus dimethylbenzene and add ad pond om 100 grams.The method that above raw material is prepared missible oil routinely drops in the mixing kettle mixes, and forms preparation 32% Acarus tritici urea chlorpyrifos ec.
Field control effectiveness test:
Embodiment is prevented and treated the field control effectiveness test of rice leaf roller, and the contrast medicine is that the result is as follows:
| Use multiple | Radix (head) | Preventive effect (%) | |||
| 2 days | 5 days | 10 days | |||
| Embodiment 1 | 1∶800 | 250 | 75.45 a | 77.32 a | 82.00 a |
