Abstract

The invention relates to an insecticide for preventing and treating diseases and pests of narcissus. The insecticide is prepared by evenly mixing the following components in parts by weight: 50-100 parts of 1,000 times liquid of 50% carbendazim wettable powder, 30-50 parts of 0.2% formalin liquid, 50-100 parts of 0.2% urea water solution, 0.5-1 part of monopotassium phosphate, 2-5 parts of liquid menthol, 1-2 parts of calcium superphosphate, 0.5-1 part of ground phosphate rock, 1-2 parts of potassium chloride, 0.01-0.02 part of borax, 0.02-0.05 part of ferrous sulfate, 50-100 parts of a quisqualis indica extract solution, 50-80 parts of a stone-like omphalia extract solution and 0.1-0.2 part of glyceryl tristearate. Through an experiment, the insecticide for preventing and treating diseases and pests of narcissus, provided by the invention, has a significant curative effect on common diseases and pests of the narcissus, the effect is the same as that of a common insecticide in the market, the recovery rate on various diseases and pests can reach over 95%, and thus the insecticide is worthy of popularization and application.

Description

A kind of pest control chemicals of narcissus

Technical field

The invention belongs to flower planting field, and in particular to a kind of pest control chemicals of narcissus.

Background technology

Narcissus, is Amaryllidaceae herbaceos perennial, and property happiness is warm, moistening, draining are good.It is existing more than 1,000 years in China Cultivation history, is traditional ornamental flower, is one of Chinese ten big famous flowers.Narcissus main pest and disease damage foxiness disease, leaf blight, line Parasitosis etc., common on the market pest control chemicals single function and toxicity is stronger is also easy to produce serious consequence after eating by mistake.

The content of the invention

In order to solve the above problems, the invention provides a kind of pest control chemicals of narcissus, toxicity is lower, while energy The pest and disease damage of enough integrated control narcissuses.

The present invention is achieved through the following technical solutions：

A kind of pest control chemicals of narcissus, are uniformly mixed by the component of following mass fraction：The clear wettable of bacterium more than 50% 1000 times of liquid 50-100 parts of pulvis, 0.2% formalin solution 30-50 parts, 0.2% aqueous solution of urea 50-100 parts, potassium dihydrogen phosphate 0.5-1 parts, liquid menthol 2-5 parts, calcium superphosphate 1-2 parts, ground phosphate rock 0.5-1 parts, potassium chloride 1-2 parts, borax 0.01-0.02 Part, ferrous sulfate 0.02-0.05 parts, fruit of Rangoon creeper's extract 50-100 parts, stone-like omphalia extract 50-80 parts, glyceryl tristearate 0.1-0.2 parts.

Further, a kind of pest control chemicals of narcissus, are uniformly mixed by the component of following mass fraction： 1000 times of clear wettable powder, 80 parts of the liquid of bacterium more than 50%, 40 parts of 0.2% formalin solution, 80 parts of 0.2% aqueous solution of urea, di(2-ethylhexyl)phosphate 0.8 part of hydrogen potassium, 4 parts of liquid menthol, 1 part of calcium superphosphate, 0.6 part of ground phosphate rock, 1.5 parts of potassium chloride, 0.02 part of borax, sulfuric acid are sub- 0.03 part of iron, 100 parts of fruit of Rangoon creeper's extract, 80 parts of stone-like omphalia extract, 0.15 part of glyceryl tristearate.

Further, fruit of Rangoon creeper's extract, its preparation method is：By fruit of Rangoon creeper's seed in -20 DEG C of freezing processings 60 Minute, it is then slightly oily to seed coat surface is gone out using fiery grillING at once, 80 mesh are crushed to after its cooling, add 75% ethanol molten Liquid obtains final product the fruit of Rangoon creeper and carries in 30kV/m electric-field intensity, 180r/min concussions alcohol extracting 20 minutes, extraction fluid recovery ethanol Take liquid.

Further, the stone-like omphalia extract, its preparation method is：

（1）Stone-like omphalia is crushed to into 120 mesh, plus the water heating of 20 times of stone-like omphalia mass fractions is boiled, and is incubated after being cooled to 60-70 DEG C 45 minutes, filter to obtain filter residue and extract A；

（2）The filter residue is added into 80% ethanol solution of 10 times of filter residue mass fractions, 30 minutes is incubated after being heated to 80 DEG C, the phase Between with 90r/min shake alcohol extracting, extraction fluid reclaim ethanol obtain final product the stone-like omphalia extract.

Beneficial effects of the present invention：The pest control chemicals of a kind of narcissus that the present invention is provided, by commonly using chemical drugs Agent, Chinese medical extract, plant growth desired nutritional act synergistically mutually, effectively kill pathogenic germ and insect, improve narcissus certainly Body resists the ability of pest and disease damage, so as to reach good prevention effect；Simultaneously, it is to avoid use chemical agent completely, reduce The toxicity of medicament, it is more safe and reliable.Through experiment, a kind of plant disease and insect pest medicine of the narcissus provided using the inventive method Agent, has significant curative effect to the common disease and pest of narcissus, and the medicament that effect is commonly used with market is identical, and various pest and disease damage cure rates reach More than 95%, it is obtained and promotes the use of.
