The invention discloses a c DNA (Complementary Desoxvribose Nucleic Acid) of a cotton bollworm COPI Beta gene and an application of the c DNA. A COPI Beta si (Small Interfering) RNA of a cotton bollworm is designed and synthesized, so that the expression of the COPI Beta gene is blocked after the COPI Beta si RNA is fed to the cotton bollworm, thus the death rate of the cotton bollworm is improved. Therefore, the biological prevention and control of the cotton bollworm is realized.

The invention discloses helicoverpa armigera V-ATPase A gene cDNA and application thereof. Helicoverpa armigera V-ATPase A siRNA is designed and synthesized, after helicoverpa armigera takes V-ATPase A siRNA in, expression of V-ATPase A gene is blocked, growth and metabolism of helicoverpa armigera are inhibited, the mortality is raised, and therefore helicoverpa armigera V-ATPase A gene cDNA is applicable to biological control of helicoverpa armigera.

The invention relates to a composition for controlling a diamondback moth of a brassicaceous vegetable and a preparation and application thereof. The composition contains two active components of chlorfenapyr(4-brombutyl-2-(4-chlorphenyl)-1-(ethoxymethyl)-5-(trichloromethyl)pyrrole-3-nitrile) and pyriproxyfen(4-phenoxylphenyl(RS)-2-(2-pyridyloxy)propyl ether), and the weight ratio of chlorfenapyr and pyriproxyfen is between 1:4 and 4:1. The composition preparation can be prepared from the composition with effective dosage, solid or liquid carriers, an auxiliary agent and other additives by a conventional method and used for processing the diamondback moth or a habitat thereof of the brassicaceous vegetable. The composition overcomes the defects of the prior art, expresses obvious synergy, can show optimal contact killing performance, stomach poisoning performance and ovicidal effect by processing the diamondback moth of the brassicaceous vegetable through applying smaller dosage, has long effect duration and simultaneously strengthens the rapid killing activity on the diamondback moth.

The invention discloses myzuspersicae hunchback gene cDNA and an application thereof; the cDNA of a key gene of hunchback (Mphb) for myzuspersicae embryonic development is transferred to a plant so as to obtain a transgenic plant which expresses Mphb dsRNA and inhibits myzuspersicae reproduction; when a myzuspersicae takes the transgenic tobacco, the expression of Mphb is inhibited; the embryonic development of the myzuspersicae is blocked; the daily mean myzuspersicae producing number is decreased; the reproductive capacity is reduced; and thus the myzuspersicae hunchback gene cDNA can be used for myzuspersicae biological control.

The invention discloses a pesticide composition containing pyrazosulfuron-ethyl and difenoconazole and belongs to the technical field of pesticide. The pesticide composition is compounded and prepared from the following effective ingredients: abamectin, pyrazosulfuron-ethyl, fluorine silicon iodine, sodium humate, 1,2-dibenzoyl-1-tert-butylhydrazine, trifloxysulfuron sodium, ethirimol, coumaphos, merida, a benzenesulfonic acid emulsifier and a benzene solvent. When a finished product of the pesticide composition is prepared, following auxiliary agents of the pesticide composition containing the pyrazosulfuron-ethyl and the difenoconazole, a dispersing agent, an additive, simethicone and water are needed, and a weight ratio of the abamectin to the pyrazosulfuron-ethyl to the 1,2-dibenzoyl-1-tert-butylhydrazine is 10 to 4 to 1. According to the pesticide composition, the two kinds of pesticides with completely different action mechanisms are mixed to achieve combined action on pests from multiple aspects to achieve the purpose of effectively preventing the pests; meanwhile, a use amount of the pesticides in fields is reduced, economical cost is saved, pollution of the pesticides to environment is reduced, and risk that the pests generate resistance to the pesticides is also reduced.

The invention relates to the field of pesticide preparations, and provides a bactericide, in particular to a sterilizing composition. The sterilizing composition comprises the following active ingredients of nikkomycin and dioctyl divinyltriamino glycine according to the mass ratio of (1 to 30) to (3 to 1), wherein the total mass of the two components is equal to 2 to 60% of the composition. Compared with single agent, the bactericide has the advantages that the number of action mechanism and dots is more, the synergism function is obvious, the generation and development of drug resistance of pathogenic bacteria are effectively delayed, the absolute usage amount of pesticide is reduced, the cost is reduced, and the pollution to environment is reduced.

The invention relates to a composition of pyriproxyfen and nitenpyram. The composition contains two active components of the pyriproxyfen and the nitenpyram, and the pyriproxyfen and the nitenpyram are blended with a solid or liquid carrier and auxiliary agents to prepare a composition preparation thereof for controlling rice planthoppers. The composition of the pyriproxyfen and the nitenpyram has obvious synergistic activity, and the compounding of the pyriproxyfen and the nitenpyram can furthest perform respective drug effects, reduce the occurrences of resistance risk of the rice planthoppers, reduce the dosage and save the cost.

Prophylaxis and treatment of estrogen-independent hyperproliferation of cells in animals or humans by means of a pharmaceutical or nutritional composition comprising a) two or more inhibitors of the G1/S phase of the cell cycle and b) two or more inhibitors of the G2/M phase of the cell cycle; and c) at least three components of the two or more protein tyrosine kinase inhibitors. In particular, component a) includes two or more compounds selected from flavonoids, carotenoids, and isoflavones; component b) includes compounds selected from flavonoids, hydroxylated stilbenes, isogenistein, and celery Two or more compounds of aglycone; component c) includes two or more compounds selected from flavonoids and isoflavones.

The invention relates to a herbicide composition, and especially relates to a herbicide composition used for controlling paddy field weed, wherein amides, clomazone, and (E)-pyriminobac-methyl are taken as the active components of the herbicide composition at a preferable weight ratio of (15-66): (1-7): (0.5-3), and the amount of the active components in the herbicide composition ranges from 22.5 to 85% preferably. The combination of the herbicide composition is reasonable; weed control spectrum is widened; controlling effect on worst weed is improved; the using amount of single-component herbicide is reduced; herbicide application times are reduced; intervals are prolonged; prevention cost is reduced; generation of drug resistance of weed on the three active components is delayed; the herbicide is safe for paddy rice, and is an ideal herbicide.
