Description

A kind of oil tea seedling stage sooty mould prevention and controls
Technical field
The present invention relates to a kind of oil tea seedling stage sooty mould prevention and controls, belong to agriculture field.
Background technology
Oil tea sooty mould is also known as sooty mould or Sooty mould.The aggrieved light influence tea oil tree growth of tea woods, and cause fruit drop, The yield and quality of tea seed is reduced, the branch dead leaf of weight falls, withered to complete stool eventually.Black coal dust shape is produced on aggrieved oil tea tree branches and leaves Lawn.Lawn is initially often produced in face of blade along master pulse on leaf, then progressively extends to full leaf down to the back side of leaf, and gradually Thicken, thickness is up to 0.5 millimeter.Lawn rough surface, or in flannelette blanket shape.The hair stage is contained in germ pycnidia, it is seen that close Raw hair on the neck microvillus is high up to 1 millimeter.Under conditions of nutrition or environment discomfort is lacked, lawn shrinks dry and cracked, can be from leaf Peel off in face.Lawn homomorphosis on sprig.The lawn of some sooty moulds, just in leaf front in the circular mildew of black, after be extended to Irregular shape, or converge the whole blade face of covering mutually.
Influence oil tea sooty mould main cause be sooty moulds be plant leaf surface saprophage, due to hinder plant light Cooperation is used and makes hazard of plant.They are main using the secretion of the insects such as a red-spotted lizard class, aphid, aleyrodid as source of nutrition, also may be used sometimes Utilize the secretion of plant in itself.Therefore, in the standing forest that these insects are caused harm, sooty mould often occurs simultaneously.
The content of the invention
It is an object of the present invention to provide a kind of oil tea seedling stage sooty mould prevention and controls, 2,3,4,9, October sprays and effectively kills Worm agent, 5,6,11, December spray effective sterilizing and kill, by desinsection and sterilizing combination, to prevent and control sooty mould, reduction Morbidity risk rate, it is ensured that the healthy growth of oil tea seedling.
The solution of the present invention for example Xias a kind of oil tea seedling stage sooty mould prevention and controls of ︰, and Bao includes Bu Zhou ︰ under Yi
（1）Annual 2,3,4,9, October, weekly to oil tea seedling spray an insecticide；
Described insecticide is by following methods get ︰ by water 56-60kg, Amitraz-Spanon-fluorobenzene urea compound 2-3kg, the moon Then osmanthus acyl glutamic acid 0.5-0.6 kg are sufficiently stirred for, up to being completely dissolved, adding sodium alginate 0.4-0.6 kg stirrings equal It is even, produce.
（2）Annual 5,6,11, December, weekly to tea shoot spray a bactericidal agent；
Described bactericidal agent by following methods get ︰ by water 70-80kg, Difenoconazole-triphenyl tin hydroxide-benzene thiophene it is clear-fluorobenzene Urea compound 3-4kg, lauroyl glutamate 1.2-18kg, polysorbate60 0.6-0.9kg mix, stirred, and produce；
（3）The local branches and leaves for just starting morbidity are removed early.
Further, described insecticide by following methods get ︰ by 58kg, Amitraz-Spanon-fluorobenzene urea compound Then 2.6kg, the kg of AESA 0.53 are sufficiently stirred for, up to being completely dissolved, adding sodium alginate 0.48 kg stirs, and produces.
Further, described bactericidal agent by following methods get ︰ by water 76kg, Difenoconazole-triphenyl tin hydroxide-benzene thiophene Clearly-fluorobenzene urea compound 3.4kg, lauroyl glutamate 1.5kg, polysorbate60 0.8kg mix, stirred, and produce；
Further, described Amitraz-Spanon-fluorobenzene urea compound mass ratio is the ︰ 0.4-0.6 of 0.25-0.28 ︰ 1.
Further, described Amitraz-Spanon-fluorobenzene urea compound mass ratio is the ︰ 0.5 of 0.26 ︰ 1.
Further, described Difenoconazole-triphenyl tin hydroxide-benzene thiophene it is clear-fluorobenzene urea compound mass ratio is 0.6- The ︰ 0.13-0.18 of 0.7 ︰ 0.32-0.36 ︰ 1.
Further, described Difenoconazole-triphenyl tin hydroxide-benzene thiophene it is clear-fluorobenzene urea compound mass ratio is 0.64 ︰ The ︰ 0.15 of 0.33 ︰ 1.
Annual March to June and 9 to November are that oil tea sooty mould is fallen ill peak period, thus select 2,3,4,9, October Spray effective insecticide.The effective ingredient of insecticide of the present invention is Amitraz-Spanon-fluorobenzene urea compound, its optimal proportion For the ︰ 0.5 of 0.26 ︰ 1.Sooty mould germ is survived the winter with mycelium, conidium, ascospore in sick portion and disease fallen leaves, next year spore Son is propagated by wind and rain, insect etc..It is retained on the secretion and excreta of the insects such as aphid, scale insect on plant.Influence is photosynthetic Act on, point secrete nectar dew insect generation such as high temperature and humidity, improper ventilation, aphid, scale insect is more, aggravates to fall ill.Pass through the present invention Insecticide can be killed effectively except above-mentioned insect, reduce morbidity risk rate.
5th, 6,11, spray effective sterilizing and kill December.The effective ingredient of bactericide of the present invention is Difenoconazole-triphenyl hydrogen-oxygen Change tin-benzene thiophene it is clear-fluorobenzene urea compound, the present invention excessively can effectively eliminate sooty mould bacterium, oil tea seedling is grown up healthy and sound.
The present invention passes through desinsection and the combination of sterilizing, on the one hand, desinsection, reduces morbidity risk rate, on the other hand, eliminates coal dirty Germ, so as to ensure the healthy growth of oil tea seedling.
