Description

A kind of citrus control shoot microbicide compositions and preparation method thereof

Technical field

The present invention relates to technical field of pesticide, and in particular to a kind of citrus control shoot microbicide compositions and its preparation side Method.

Background technique

Citrus ulcer is a kind of worldwide disease, this disease originates from Asia, and the most universal in Asian countries's generation.Its It is also universal one of the disease in China's citrus producing region, in the citrus producing region such as Guangdong, Guangxi, Hunan, harm is particularly acute.The disease is A kind of bacterial disease forms the scab of crateriform, size 2-8mm on leaf, branch, fruit after citrus is aggrieved, the later period causes to fall Leaf, shedding, influence fruit yield and quality.This disease mostly occurred in annual early April to late November, the spring tip of mainly causing harm, Summer shoot and autumn growth, aggrieved the most serious with summer shoot, autumn growth, germ can infected group through stomata, hole skin and wound infection plant It is bred rapidly in knitting, stimulation host cell increases until dead after histocyte swelling rupture.Currently, the mostly useization in production Length of schooling agent is prevented and treated.Start to spray copper agent (such as bohr after 7 days or so and summer shoot, autumn growth rudiment generally after spring tip lamina More liquid, copper oxychloride, copper acetate etc.), the fungicide such as antibiotic (such as streptomycin sulphate, gold alloy hydride), sprayed one every 7-10 days It is secondary, it sprays 3 times altogether.

Anthracnose of orange is that one of universal, serious disease of harm, the main citrus of causing harm of the disease occur for China citrus producing region The organs such as blade, branch, flower and fruit, cause fallen leaves, spike top, fallen flowers, shedding and decayed fruit etc., tree vigo(u)r caused to fail, the underproduction Even have no harvest.The disease is the fungal disease as caused by anthrax-bacilus, through wind and rain or arthropod-borne, by stomata, hole skin, wound or It is directed through epidermis and infects plant tissue.In order to prevent and treat the disease, in production generally after fallen flowers and in fallen flowers the latter half a month It sprays after fallen flowers and in fallen flowers the latter half a month, is sprayed 1 time every 10d or so, continuously spray 2~3 times, spray 1 again between 7, August It is secondary, to prevent shedding.Medicament can be gone out 500 times of liquid of disease prestige with 40%, 65% 500 times of Zineb wettable powder liquid, 70% thiophanate methyl 800~1000 times of liquid of wettable powder, 50% 800 times of carbendazim liquid.

Blue mould of citrus and green mould are that universal, the serious disease of harm occurs with after adopting before citrus is adopted, and are mainly caused harm Fruit causes fruit mildew, rots.The disease is passed through mainly by Penicillium notatum or the microbial fungal disease of green mold by spore Wound invades citrus fruit.Currently, other than the condition for improving harvesting and storage, it is main or by chemical agent to fruit into Row processing: can with three octyl benzene sulphur salt 1000-2000 times of liquid+ten thousand of 40% wettable powder of biguanides it is sharp 1000-2000 times of liquid, 500 times of liquid of 70% thiophanate methyl wettable powder or 50% carbendazol wettable powder.

But excessively rely on chemical bactericide and disease is prevented and treated, it be easy to cause germ to develop drug resistance, agricultural product agriculture The series of negative such as residual exceeded, environmental pollution influence.And carrying out biological control using natural plant extract has to environment friend Good, safe low-residual not easily leads to the advantages that drug resistance generates.Existing research show garlic, ginger, China pink, eucalyptus leaves, Leaf of Lonicera hypoglauca Miq, purslane extract inhibition is all had to staphylococcus aureus, escherichia coli, bacillus subtilis etc. Effect, Activities of Some Plants extract even better than compare antibiotic to the inhibition efficiency for trying bacterium.Therefore, in mandarin orange planting production Use the composition of these plant extracts that also there is certain application prospect as fungicide.
