The Special Mango tree is very sturdy, with a high canopy and large, sparse flowers. The fruit is extra-large, with a thin heart, sweet and refreshing, juicy, fiberless, and resistant to storage and transportation.
I. Thrips
Thrips in the early flowering of mango that damage, the most serious damage in full bloom. With the arrival of the small fruiting period, the insect population decreases significantly. The damage will be more serious if warm and dry weather is encountered when mangoes are growing, flowering and fruiting.
Prevention methods:
1. First, strictly control the germination of winter tips and bend some new tips to reduce the food source of thrips.
2. Usually pay attention to the field more watering, increase the humidity of the orchard. Remember to water evenly, not more or less, as this can lead to fruit cracking and dropping at a later stage.
3. Yellow or blue sticky insect panels can be hung in the field to trap insects. According to experimental statistics, the trapping effect of basket boards is better than that of yellow boards. This method can remove a large number of adults.
4. Pay attention to field orchard management, timely removal of weeds; stay away from melons and vegetables, try not to plant with vegetables; it can be garnished with mint, rosemary, lavender, sage and other insect-repellent plants; reasonable dense planting and scientific pruning, keep the orchard ventilated and transparent.
5. Chemical control, as thrips are prone to drug resistance, fruit growers are advised to use a variety of chemicals alternately.
II. Horizontal leaf tail moth
1. Artificial control, brush lime water on the trunk to create an environment unfavorable to the pupation of larvae; in the orchard with serious infestation, the trunk can be wrapped in plastic film with coco coir, straw or rice straw to lure mature larvae into the pupa, and then taken out regularly to be incinerated.2. Chemical control, according to the characteristics of the infestation, the prevention and control should be carried out in the egg stage of larvae and the juvenile age period. In general, spraying should be carried out when the mango branches and flower spikes are 3-4 centimeters long, so that the young branches can be protected from the horizontal tail leaf moth.
III. Leaf Gall Midge
Leaf gall midge bites the epidermis of young leaves and burrows into the leaf flesh to feed on it. Injured leaves develop brown spots and leaf curling after white spots, perforations and ruptures are seen. In severe cases, the leaves wilt and fall off, causing the shoots to wilt.
Prevention methods: 1. Leaf gall mosquitoes like warm and humid climate and shady environment, attention should be paid to removing weeds and dead leaves in the orchard, pruning the canopy, maintaining orchard ventilation and light penetration. 2. Focus on extracting new shoots and young leaves of 3~5cm and back spraying before and after the expansion of the young leaves to protect them, preventing adults from ovipositing and killing the newly hatched larvae. Spray every 7~10 days, spray 2~3 times in a row.
