Problems solved by technology

[0005] At present, the control methods of mangrove sooty disease basically follow the control method of terrestrial plant sooty disease, either the effect is not good, or it has a great impact on the marine environment where the mangrove is located; and few of them are specifically aimed at mangrove. The tidal environment has developed a soot control method suitable for mangroves

Embodiment 1

[0024] A method for preventing and treating mangrove soot, comprising the following steps:

[0025] (1) Collecting snails: In mangrove areas free of sooty snails, collect snails and snails that live on the leaves of mangroves. The collected snails are packaged with gauze and used within 24 hours after collection.

[0026] (2) release snails: in the ebb tide period in the morning and evening, put the snails collected on the mangroves in the mangrove area where sooty fouling occurs, and for the mangroves with a smaller diseased area, each plant is controlled. Evenly move 20-30 shore snails into the diseased tree, and place the shore snails at the intersection of the petioles of the top leaves during transfer; for mangroves with a large diseased area, use the method of sprinkling, directly throwing the shore snails to the canopy of the mangroves, Sprinkle 20-30 snails per square meter.

[0027] (3) Spraying agents: 8 days after the release of the snails, the mangroves were spray...

Embodiment 2

[0031] A method for preventing and treating mangrove soot, comprising the following steps:

[0032] (1) Collecting snails: In mangrove areas free of sooty snails, collect snails and snails that live on the leaves of mangroves. The collected snails are packaged with gauze and used within 24 hours after collection.

[0033] (2) release snails: in the ebb tide period in the morning and evening, put the snails collected on the mangroves in the mangrove area where sooty fouling occurs, and for the mangroves with a smaller diseased area, each plant is controlled. Evenly move 20-30 shore snails into the diseased tree, and place the shore snails at the intersection of the petioles of the top leaves during transfer; for mangroves with a large diseased area, use the method of sprinkling, directly throwing the shore snails to the canopy of the mangroves, Sprinkle 20-30 snails per square meter.

Embodiment 3

[0038] A method for preventing and treating mangrove soot, comprising the following steps:

[0039] (1) Collecting snails: In mangrove areas free of sooty snails, collect snails that live on the leaves of mangroves. The collected snails are packaged with gauze and used within 24 hours after collection.

[0040] (2) release snails: in the ebb tide period in the morning and evening, put the snails collected on the mangroves in the mangrove area where sooty fouling occurs, and for the mangroves with a smaller diseased area, each plant is controlled. Evenly move 20-30 shore snails into the diseased tree, and place the shore snails at the intersection of the petioles of the top leaves during transfer; for mangroves with a large diseased area, use the method of sprinkling, directly throwing the shore snails to the canopy of the mangroves, Sprinkle 20-30 snails per square meter.

[0041] (3) Spraying agents: 7 days after the release of the snails, the mangroves were sprayed with 10 ...

Abstract

The invention discloses a method for controlling sooty mould of mangrove.The invention utilizes the preference characteristics of littorina for bacteria and algae.The littorina is first released for controlling sooty mould of mangrove; the mangrove is sprayed with a plant-derived agent consisting of sophocarpidine, table salt, chitin, a cinnamon extract and an eucalyptus leaf extract to control the sooty mould of mangrove; finally a small number of littorina is released again to prevent the sooty mould of mangrove.The method of the invention is simple, easy to operate, easy in obtaining raw materials, and low in cost; the removal rate of the sooty mould of mangrove is 99.8% or higher, and the sooty mould is not liable to recur; the method has good economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of biological control of plant protection, and in particular relates to a method for preventing and controlling mangrove soot. Background technique [0002] Soot is a fungal disease that grows on the surface of plants and is suitable for growing in a warm and humid environment. Mangrove soot is caused by complex flora, among which the sooty of tung tree in Leizhou Peninsula is caused by Cladosporium sphaerospermum, Leptoxyphium fumago, Acremonium rutilum and Zasmidium citrigriseum; Guangxi coastal tung tree coal pollution is mainly caused by Capnodium anona, Asterina maesae, Fumagovagans, shield shell Caused by Coniothyrium sp.; Hong Kong GOH isolated three pathogens of Trimmatostroma sarcinifome, Trimmatostromabotyoforme and Trimmatostroma variabile from tung tree soot spots on Tingjiao Road on the north shore of Tolo Harbor in Hong Kong . [0003] Sooty rot is a combination of bacteria and algae, which ...
