Description
Technical field
The present invention relates to technical field of pesticide, particularly a kind of pesticidal preparations of preventing and treating vegetable-crop pest-insects such as diamond-back moth.
Background technology
Diamond-back moth (Plutella xylostella) is one of primary pest of brassicaceous vegetable.Its cross resistance spectrum is wide, resistance level is high, reproduction speed is fast, vegetables is produced caused very big threat.At present to organic phosphates, carbamates, pyrethroid, Bt, Avermectin, insect growth regulator, IGR class, even plant insecticide etc. all produced resistance in various degree, is one of the most serious insect of development of drug resistance.In recent years, the chemical agent of some mechanism of action novelties and biopesticide are developed in succession and are used to prevent and treat diamond-back moth, as capillary, butyl ether urea, Avermectin etc.; But various medicaments still lack comparison to the control efficiency of diamondback moth larvae.In order to control causing harm of diamond-back moth better, filter out the best method of control diamond-back moth.
Flubendiamide (flubendiamide) is the novel pesticide that Japanese agricultural chemicals company and Bayer are developed jointly, and is mainly used in vegetables, fruit, paddy rice and cotton control lepidoptera pest; Not only adult and larva are all had good activity, and speed of action is fast, the lasting period is long.Because therefore mechanism of action uniqueness does not have cross resistance with conventional pesticides; To segmental appendage class beneficial insect safety, be suitable for the insect comprehensive regulation and pest resistance treatment.Flubendiamide is different from conventional pesticides, is the ryania receptor activators.After using Flubendiamide, the classical symptom of lepidopterous larvae is health atrophy gradually, and similar symptom can be seen on one's body the insect after handling through ryania, and ryania is a calcium ion release channel adjuster; The calcium ion release channel serves as crucial effect in contraction of muscle, this shows and relates to the responsive like this calcium ion release channel mechanism of ryania that resembles in the insecticide Flubendiamide mechanism.Flubendiamide has good active to diamond-back moth 3 instar larvaes that cinerins, benzoyl area kind, organic phosphates, carbamates have produced resistance.Flubendiamide is to the EC of diamond-back moth adult
50Value is for 0.21mga.i./L, and is suitable with cyhalothrin; Activity to 2 instar larvaes is the highest, EC
50Value is 0.004mga.i./L, is 60 times of cyhalothrin, but to the ovum non-activity.Active testing result to 3 different instar larvaes of prodenia litura shows that Flubendiamide is the most effective to 1 instar larvae, and 3 ages and 5 instar larvaes take second place.Flubendiamide is compared with cyhalothrin, Methomyl, Profenofos, pleocidin, even 5 instar larvaes have also been shown very high activity.
Rotenone (rotenone) is a kind of plant insecticide that exploitation is worth that has very much.Alternative nerve fiber and the muscular tissue of suppressing, absorption in not having, have strong tag, stomach toxicity has certain repellent, food refusal and the inhibition effect of growing concurrently.Its insecticidal action is slow, but insecticidal action is more lasting, can keep about 10 days.Rotenone insecticidal activity height, insecticidal spectrum is wide, and known its has preventive effect to 137 section's 800 various pests of 15 orders at present, is mainly Lepidoptera, Homoptera, diptera, coleoptera, Hymenoptera.Rotenone is classified as 21 century by State Development Planning Commission and the Department of Science and Technology and is first developed industry, is confessed in the world environment friendly agricultural.Especially use on directly edible economic crops such as vegetables, fruit tree, tealeaves, more apparent its advantage can not only be produced quality-assured vegetables, relieved fruit, relieved tea, and can also improve crop quality, improves mouthfeel, is the desirable medication in green agricultural product base.
Rotenone has the strong performance of tagging to insect, and 800 various pests are had biologically active preferably, and is especially remarkably productive to the aphid mite pest, be anti-eliminate aphis, the special effect agent of diamond-back moth, imported cabbageworm and citrus red mite.Rotenone is classified as 21 century by State Development Planning Commission and the Department of Science and Technology and is first developed industry, is confessed in the world environment friendly agricultural.。
But the unitary agent of above rotenone preparation and Flubendiamide has run into serial problem in actual use.As rotenone preparation rotenone in use in the field photodissociation, hydrolysis etc. take place easily in natural environment easily, make drug effect, the lasting effect of rotenone be subjected to influence, the control efficiency of insect has been subjected to certain influence.Flubendiamide has the better prevention effect to vegetable-crop pest-insect at present as a kind of chemical pesticide, but in order to improve the control efficiency of medicament to insect, the peasant constantly improves the using dosage of medicament, has increased the weight of insect to the drug-fast generation of medicament.
Summary of the invention
