Abstract
The invention discloses a new method for controlling mulberry pests. In the technical scheme, the method comprises the following steps of: mixing 2 percent bitter general ginseng alkali and water in a volume ratio of 1:(600-2,500), spraying 45 and 55 kilograms of the mixture to leaf surfaces of mulberry in each 667 square meters of soil, and after applying for 4 hours to 5 days, picking leaves normally to feed silkworm. A pesticide prepared by the method is easy to prepare, wide in source of raw materials, low in price, non-toxic to human and livestock, pollution-free and convenient to use, and can be sprayed on the leaf surfaces of the mulberry directly, residues are avoided, mulberry leaves can be picked to be fed to the silkworm after several hours, and the mulberry leaves which are sprayed by the pesticide diluted by 2,000 times can be picked after 4 hours to be fed to the silkworm. Experiments indicate that the control effect on mulberry looper, euproctis similis, white tiger moth, large dagger moth, ascotis selenara dlanera hubner, pseudodendrothrips mori and red spider is 90 percent, and the control effect on mulberry pyralid moths and wild silkworm is poor (only 10 percent). The method is popularized and applied to about 3 hectares of mulberry fields in the Teyong town of Sheyang county and the Xinfeng town of Dafeng city of Jiangsu province, and the satisfied control effect is achieved.
Description
Technical field
Patent of the present invention relates to a kind of new method of preventing and treating of preventing and treating the mulberry tree insect, particularly a kind of also operable, environmentally safe in the season of breeding silkworms, to the new method of the preventing and treating person poultry safety, that several hrs can picking leaves be fed silkworm after the dispenser.
Background technology
Along with the use of high-toxic pesticide and the variation of environmental condition, variation has taken place in the pesticide resistance of most of mulberry tree insect, adopts traditional method of preventing and treating, and has been difficult to control it effectively and has caused harm.Constantly saw all parts of the country arranged the report of " outburst of mulberry tree insect is caused harm, and mulberry leaf are eaten up back no mulberry leaf hello silkworm " in recent years.Can buy, obtain national Ministry of Agriculture registration card on the current market, be used to prevent and treat the chemical pesticide commonly used of mulberry tree insect, the enemy enemy as 80% feeds 1500 times of 1500 times, 50% phoxim etc.; Drug effect is single, has only the control efficiency about 30～70%, in addition to the high poison of people and animals; High residue; Particularly summer the mulberry field height of tree, day heat, strongly fragrantly cover, stuffy, careless slightly, people and animals and silkworm intoxication accident very easily take place.
Summary of the invention
For overcoming the weak point of prior art, the present invention provides a kind of raw material sources wide, cheap; Control efficiency is good, short to the silkworm residual hazard phase; Prepare simple,, noresidue, pollution-free nontoxic to people and animals, easy to use, can directly spray on the blade face of mulberry tree; Can pluck after several hours and feed silkworm, utilize the new method of preventing and treating of plant source pesticides total alkaloids of sophora flavescens control mulberry tree insect.
The technical solution adopted for the present invention to solve the technical problems is: this medicine comprises Banlangen and water, and the volume ratio of 2% ginseng total alkali and water is 1: 600～2500.This medicine sprays on the blade face of mulberry tree with the consumption of per 667 square metres of (mu) 45～55 kilograms of dilutions, uses after 4 hours～5 days normally picking leaves and feeds silkworm.
Water described in the above-mentioned medicament is the water of neutrality or meta-alkalescence, and the pH value is 7.0～7.5.
2% Banlangen that the present invention adopts be the approval of the national Ministry of Agriculture to people and animals' low toxicity, less-persistent pesticide, be used for the control of the common insects of large crops such as vegetables, fruit tree, paddy rice, soybean.2000 times of dilutions are 90.32～95.18% to mulberry geometrid (Hemerophila atrilineata), cotton big bridging worm control efficiency; Control efficiency to mulberry tussock moth, white tiger moth is 89.73～91.22%; Control efficiency to mulberry thrips, two spotted spider mite is 89.89～93.87%, and its control efficiency is significantly higher than conventional contrast agricultural chemicals.But the control efficiency to diaphania, wild silkworm is merely: 3.13～19.22%, extremely significantly be lower than the contrast agricultural chemicals.After 2000 times, 1500 times, 1000 times dilutions spray mulberry tree, the safety interval of silkworm was respectively 4 hours, 8 hours and 32 hours.Pluck the mulberry leaf of personal distance after date and feed silkworm, major physiological index and the economic indicator of silkworm had no adverse effects.
The botanical pesticide of control mulberry tree insect of the present invention, the control efficiency of its laboratory test (seeing table 1).
