Abstract

The name of the invention is a specifically effective formula for controlling Phyllotreta striolata. The invention belongs to the agricultural science in terms of disciplines, the agricultural field in terms of technologies, and the subfield of plant protection. The main components of the formula comprise pyridaben and acetamiprid. Then a certain amount of specifically effective penetrating spreading agent organosilicon is added, and the mixture is processed into a specific dosage form, either missible oil or a suspending agent. The missible oil is the easiest to process and has the most obvious effect. Mainly used to control Phyllotreta striolata, the formula of the patent has an ovicidal action on Phyllotreta striolata and also can kill the imagoes. One time of drug application can solve pests of various stages. The control duration period is effectively prolonged from 3-4 days of general pesticides to 15 days, thus greatly reducing labor cost and drug cost. The formula of the patent is characterized by simple preparation process and low cost, and is suitable for promotion and application.

Description

A kind of control phyllotreta striolata specific prescription

Technical field

Ambit is an agricultural science under this patent, and affiliated technical field is an agricultural, and the segmentation field is plant protection.

Background technology

Phyllotreta striolata belongs to coleoptera, Chrysomelidae insect, is commonly called as dog mite, flea, is called for short flea beetle, the leaf vegetables of often causing harm.Phyllotreta striolata have every year spring and summer and winter two peak periods of causing harm, normal because winter vegetable is more (special Cruciferae dish is more), foodstuff is abundant; Temp. and humidity is very suitable, and wildness causes harm: adult gnaws blade, causes blade hole, photosynthesis to reduce; Only surplus at last vein, in addition dead; Larva stings food root skin in soil, make root water uptake, and fertility descends.Cause the vegetable grower to spray medicine in a large number, cause residue of pesticide very serious, and usually can not receive desirable deinsectization effect.

Phyllotreta striolata becomes the long 1.8-2.4 millimeter of polypide, and it is long partly that pitch-dark look, flagellum are about body, a summary is respectively arranged like the vertical spot of the yellow of bow type on the elytrum, and the color spot middle part is slightly narrow and crooked.The metapedes leg section is flourishing especially.Ovum is oval, and is faint yellow.The mature larva body is about 4 millimeters, long tubular, and yellow-white, head and pronotary are filbert, and 3 pairs of pereiopoda are only arranged, the verruca that the equal tool of each body segment is not really outstanding.Exarate pupa is oval, and is faint yellow, is about 2 millimeters.

The annual generation 7-8 generation in the area, Guangzhou, generation overlap does not have and significantly survives the winter the phase, the whole year all desirable food and breeding, but to cause most serious harm the 3-5 month and the 9-11 month.Adult is kind to jump, especially with the most active after before midday, and tool phototaxis, responsive to black light lamp.Lay eggs in host's root or near table soil, loose and produce, the adult egg-laying period can continue 30-45 days, every female on average laying eggs about 200.In the time of 26 ℃, 4-9 days ovum phase; Larva hatches the back and is eaten to main root by fibrous root, and stripping food root skin focuses mostly in the native face 3-5 of distance centimetre depths, and larva is totally 3 ages, goes through phase 11-16 days; The end instar larvae is many pupates 11-13 days pupa time as the chamber in 3-7 centimetre of dark soil.

Annual serious to take place in spring, two seasons of autumn, especially to attach most importance to autumn; Cause harm and overweight the low field of vegetables of humidity in the vegetable plot that humidity is high.

Acetamiprid is the new high-efficiency nicotinic insecticide of Japanese Cao Da company exploitation, is to go up synthetic nicotimine insecticides on Nitromethylene (Imidacloprid) type basis, has the brand-new mechanism of action.Though it and Imidacloprid belong to a series of, its desinsection scope is wider than Imidacloprid, and is better to the control efficiency of insect.Superpowerly tag except that having, the stomach toxicity, strong osmosis, characteristics such as absorption is strong in also having, consumption is few, quick-acting good, the lasting period is long.Be mainly used in anti-eliminate aphis, homoptera pests such as leafhopper, aleyrodid, but be that effect is remarkable too for the control of the coleopteran pest led to longicorn and phyllotreta striolata.Acetamiprid belongs to medium pesticide, is super-active never poison of new generation.To skin and eyes nonirritant, animal experiment does not have mutagenesis.Its mechanism of action is nerve conduction effect in the interference insect, through combining with acetylcholinergic receptor, suppresses the activity of acetylcholinergic receptor.Because its unique mechanism of action, the insect that organic phosphors such as chlopyrifos, Aphox, pyrethroid, carbamate insecticide is produced resistance there is good result.

Pyridaben is wide spectrum, tagging property miticide, can be used for preventing and treating multiple food vegetalitas evil mite, has characteristics such as desinsection is fast, the lasting period long, control efficiency is good.The pyridaben insecticidal mechanism is unique, and the various fertility worm attitudes of crop evil mite (ovum, young mite, if mite, one-tenth mite) are all had good control efficiency.Security performance is good, does not pollute fruit surface behind the medicine, does not stimulate pericarp, does not all have cross resistance, resistance of rainwater washing against with miticide dicofol commonly used, organotin, pyrethroid etc.No matter temperature influence not under high temperature still is cryogenic conditions, uses pyridaben all to have same effect.

In general, it is the homoptera pest of representative that Acetamiprid is used for preventing and treating with aphid, trialeurodes vaporariorum, and pyridaben only is used for preventing and treating harmful mite; Up to the present, also not with pyridaben with Acetamiprid is composite prevents and treats the phyllotreta striolata related patent U.S. Patent No., but the author finds in process of the test; Pyridaben and Acetamiprid composite very good to the phyllotreta striolata effect; Can not only prevent and treat larva, and can prevent and treat adult, also possess certain ovicidal action.

Summary of the invention

The present invention is a main component with pyridaben and Acetamiprid, is aided with and efficiently sprawls the bleeding agent organosilicon, processes missible oil or suspending agent; Be used for preventing and treating phyllotreta striolata; The content of pyridaben is 5-15% (weight ratio), and the content of Acetamiprid is 5-15% (weight ratio), and organosilicon content is 3-6% (weight ratio); The ratio of pyridaben and Acetamiprid is 1: 1, and the mu dosage is a 5-10 gram (being converted to the former medicine of 100% content).
