Abstract

The invention discloses a fungicide for rice blast of rice. The fungicide is prepared from the following effective components: metominostrobin and a plant extract at the weight ratio of (0.1-0.5) to (6-12), wherein the plant extract is a mixture of a poke root extract, a garden burnet root and stem extract, a selfheal ear extract, a radix euphorbiae lantu root extract and a cortex lycii radicis root and skin extract; and the weight ratio of the poke root extract to the garden burnet root and stem extract to the selfheal ear extract to the radix euphorbiae lantu root extract to the cortex lycii radicis root and skin extract is (1-2) to (1-2) to (3-4) to (3-4) to (1-2). The metominostrobin and the plant extract are compounded, so that the condition that the activity of the composition is more significant than that of individually used metominostrobin is ensured; the fungicide is good in sterilization effect, fast to take effect, and relatively endurable in prevention and treatment; meanwhile, the fungicide is safe to crops, and stable and safe in chemical property; the damages to the environment caused by a chemical pesticide are reduced; and the residue of harmful components in the soil is reduced.

Description

A kind of bactericide for rice blast
Technical field
The invention belongs to bactericide technical field, be specifically related to a kind of bactericide for rice blast.
Background technology
For a long time, chemical pesticide control damage by disease and insect, because it is efficient, quick-acting, cheap and easy to use, is in monopolization in place in plant protection.Along with the people are to pay attention to day by day that is healthy and environmental problem, chemical pesticide enjoys people to query because of problems such as it is residual, environmental pollutions.Particularly directly affect the healthy food of people, " Green Trade Barrier " has been carried out in countries in the world, limits the residual quantity of chemical pesticide.Therefore, less with chemical pesticide and find alternative chemical pesticide and carry out disease control and become the emphasis studied in the future.
SSF 126 (Metominostrobin) is the systemic fungicide that a kind of New-type wide-spectrum, protection and therapeutic activity have concurrently.Control rice blast has special efficacy, not to infect or their early stage is used at rice blast.Prevent and treat that to produce the bacterial strain of resistance to 14-demethylation enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole effective, there is protection, treat, root out, permeate, systemic activity.
Rice blast also known as rice blast, burn pest, pest of kowtowing, be distributed in national Ge Dao district, mainly to cause harm blade, stem stalk, fringe portion, because period of causing harm, position difference are divided into seedling pest, leaf pest, joint pest, panicle blast, grain pest, seedling pest, before betiding three leaves, caused by seed-borne fungi, sick seedling base portion is greyish black, top browning, to crispatura and dead, when humidity is larger, disease portion produces the mould layer of a large amount of grey black, i.e. pathogen conidiophore and conidium, and rice blast is one of large disease of paddy rice four, time serious, cause that No kernels or seeds are gathered, as in a year of scarcity.For the placement of rice blast, prevent and treat with chemical pesticide for a long time, consumption is many always, and pedo relict is serious, harm Environmental Health.
Summary of the invention
For the defect existed in prior art, the object of this invention is to provide a kind of bactericide for rice blast.
Described a kind of bactericide for rice blast, it is characterized in that being made up of active ingredient SSF 126 and plant extracts, the weight ratio of described SSF 126 and plant extracts is 0.1-0.5:6-12, described plant extracts is the mixture of pokeberry root extract, garden burnet rhizome extract, selfheal raceme extract, chameajasme extract and root bark of Chinese wolf-berry root bark extract, described pokeberry root extract: garden burnet rhizome extract: selfheal raceme extract: chameajasme extract: the weight ratio of Cortex Lycii extract is 1-2:1-2:3-4:3-4:1-2.
Described a kind of bactericide for rice blast, is characterized in that the weight ratio of SSF 126 and plant extracts is 0.2-0.4:8-11.
Described a kind of bactericide for rice blast, is characterized in that the weight ratio of SSF 126 and plant extracts is 0.3:10.
Described a kind of bactericide for rice blast, is characterized in that described pokeberry root extract: garden burnet rhizome extract: selfheal raceme extract: chameajasme extract: the weight ratio of Cortex Lycii extract is 1.5:1:3:4:1.
Described a kind of bactericide for rice blast, is characterized in that described plant extracts adopts following methods preparation:
1) get pokeberry root, garden burnet rhizome, selfheal fruit ear, chameajasme, root bark of Chinese wolf-berry root skin dry after cleaning up respectively, dry to water content 10-15% under the temperature condition of 40-60 DEG C, cracker is pulverized, and crosses 40 mesh sieves, for subsequent use;
2) get the pokeberry root after pulverizing, acetone that garden burnet rhizome, selfheal fruit ear, chameajasme, root bark of Chinese wolf-berry root skin add 10-30 times amount respectively, be positioned on shaking table and carry out concussion extraction after 24 hours, filter, respectively an extract of obtained each plant;
3) by through step 2) each filter residue after process adds the acetone of 10-30 times amount respectively, and be positioned on shaking table and carry out concussion extraction after 24 hours, filter, obtain the secondary raffinate of each plant respectively;
4) corresponding for each plant extract and secondary raffinate are merged, be evaporated to the 5-10% of original volume, to the extract of deserved each plant.
The present invention is by being undertaken composite by SSF 126 and plant extracts, and guarantee that the specific activity of composition is used alone the activity of SSF 126 more remarkable, bactericidal effect is good, and instant effect, control are more lasting; Meanwhile, this bactericide is to crop safety, and stable chemical nature, safety, reduces the destruction that chemical pesticide brings to environment, and in minimizing soil, harmful components is residual.
