Description
Technical field
The present invention relates to a kind of composition pesticide and application thereof, be specially a kind of complex insecticidal composition and the application of said composition on control crop lepidoptera pest that contains methoxyfenozide.
Background technology
In the real process of agricultural production, chemical control is a kind of important means of agricultural production insect pests.In chemical control, the problem that is easy to generate most is the generation and the development of germ and pest resistance to insecticide.
Beet armyworm is one of important pests of whole world vegetables, melon and fruit production, and it is wide to distribute, and feeding habits are assorted, and each breeding amount is big, and its larva exocuticle smooth surface, is being difficult for medicine.Its pesticide resistance in the whole nation in addition the whole world a lot of reports are all arranged.In China, beet armyworm all has obvious pesticide resistance to all organic phosphors, chrysanthemum ester and carbamate medicament.People such as the Liu Yong outstanding person of Agricultural University Of Nanjing report, Shenzhen, Hunan, Shanghai, Changshu and Nanjing population 3 instar larvaes to 5 kinds of insecticides resistance, the result shows: the highest to the beta-cypermethrin resistance, belong to high horizontal resistance (172.1～408.7 times); Secondly be cyfluthrin (42.7～109.8 times) and chlopyrifos (21.0～50.3 times), belong to medium～high-level resistance.And Tai'an, Shandong resistant population to the resistance of cyhalothrin up to 2445.5 times.
Prodenia litura also is a kind of worldwide insect, it is wide to distribute, endanger 99 sections, 209 plant species, because of its breeding amount big, breeding is fast, generation overlap is obvious, since the sixties in 20th century, in Taiwan of India, Egypt, Japan, Turkey and China, ground such as Shanghai successively has prodenia litura multiple insecticide all to be produced the report of resistance.People such as the Wu Shichang of plant protection research institute of Shanghai Academy of Agricultural Sciences also road prodenia litura are respectively 43.9,90.5 and 171.9 times to the resistance of cypermethrin, decis and sumicidin; Resistance to dichlorvos, orthene is respectively 29.7 and 33.6 times.
Easily produce the lepidoptera pest of resistance for control prodenia litura and this class of beet armyworm, one of way of chemical control is to release the new component that new and existing kind do not have cross resistance.But, the development cost height of new active ingredient, the construction cycle is long, and all is unable to catch up with the speed that insect produces resistance forever.Other method such as crop allocation adjustment, different agricultural chemicals are rotated etc., in the process of practical operation, are difficult to really play obvious effects.Therefore, the medicament that can prevent and treat resistant diagonal noctuid and beet armyworm at present extremely lacks.
Different farm chemical ingredients carry out composite after, be synergy, addition or antagonism, unpredictable.And, have only compound synergic well to fill a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, could delay the generation of pest resistance to insecticide greatly.
Emamectin-benzoate (being called for short first dimension salt), English name Emamectin Benzoate, it is a kind of new and effective semisynthetic antibiotics insecticide that begins to synthesize from fermented product Avermectin B1, it has super-high-efficient, low toxicity (preparation is closely nontoxic), noresidue, the nuisanceless characteristics that wait biopesticide, active high to the larva of lepidopterous insects and other many insects and mite class, the double again action of contace poison of existing stomach poison function, under low-down dosage, have good effect, and in the process of pest control, beneficial insect is not injured, help integrated control insect.This medicament and Avermectin belong to medicament of the same type, and higher cross resistance risk is arranged, and use separately easily to produce resistance.
There is Cao of Southwestern University to keep the development of report of good news road 7.1% methoxyfenozide first dimension salt missible oil at present, content relates generally to the method for production of missible oil, wherein also mention an effective ingredient proportioning (methoxyfenozide: first dimension salt is 70: 1), but just determine according to individual research needs and agricultural chemicals bulletin, do not pass through the research of proportioning aspect, also undeclared two composite reagents have synergistic effect and disclose any related data.
