Citrus Disease Treatment
1. Citrus Canker
Citrus canker is a citrus disease caused by the bacterium Xanthomonas axonopodis. While not harmful to humans, canker significantly affects the vitality of citrus trees, causing leaves and fruit to drop prematurely. A fruit infected with canker is safe to eat, but has reduced marketability as fresh fruit.
Symptoms:
Citrus canker causes lesions on citrus leaves, stems, and fruit. Characteristic lesions are raised and brown, have water-soaked margins, and usually have a yellow halo surrounding the lesion. Older lesions appear corky.

2. Citrus Anthracnose
Anthracnose cause by Glomerella cingulata (stonem) Spauld. et Schrenk. This pathogen is a primary colonizer of injured and senescent tissue. The organism grows on dead wood in the canopy, and it spreads short distances by rain splash, heavy dew, and overhead irrigation.
Symptoms:
Leaf - common symptoms are a more or less circular, flat area, light tan in color with a prominent purple margin that at a later phase of infection will show the fruiting bodies of the fungus (tiny dispersed black flecks). Tissues injured by various environmental factors (such as mesophyll collapse or heavy infestations of spider mites) are more susceptible to anthracnose colonization.
Fruit - anthracnose usually only occurs on fruit that have been injured by other agents, such as sunburn, chemical burn, pest damage, bruising, or extended storage periods. The lesions are brown to black spots of 1.5 mm or greater diameter. The decay is usually firm and dry but if deep enough can soften the fruit. If kept under humid conditions, the spore masses are pink to salmon, but if kept dry, the spores appear brown to black. On ethylene degreened fruit, lesions are flat and silver in color with a leathery texture. On degreened fruit, much of the rind is affected. The lesions will eventually become brown to grey black leading to soft rot.

3. Citrus Yellow Shoot
Citrus yellow shoot can be graft transmitted but transmission rates are variable because of irregular distribution of bacteria within the host plant. The most important method of disease spread occurs by the two species of psyllids that serve as vectors. Citrus yellow shoot is systemic and has an incubation period of three months to multiple years before symptoms are visible.
Symptoms:
Leaf - although symptoms differ according to citrus variety, common symptoms may be described. The most characteristic symptom of HLB is a blotchy mottle. This mottling is distinct from nutrient deficiency in that HLB induced mottling usually crosses the veins and is asymmetrically displayed on the leaf blade. Mottling is most frequently found on newly mature hardened-off leaves but fades with leaf age. The blotchy mottle will be visible on both sides of the leaf and have multiple hues of yellow and green.
Fruit - fruit may be small and lopsided. Cut fruit may have a curved axis and the vascular columella can be stained orange-brown.
Whole tree - the irregular distribution of symptoms on the tree corresponds with the irregular distribution of the bacteria in the tree. On severely infected trees, foliage may be sparse with the top third of the canopy being thin. Eventually the tree may go into a complete decline, collapse, and die. Trees with a prolonged infection appear stunted when compared to healthy trees.

Citrus Pest Control
1. Citrus Aphid
Aphids are tiny insects and nearly all individuals are egg-laying females that produce live young. Males are only needed to produce over-winter capable eggs, so hatching and growing Aphids can create rapid infestations. Because of this, Aphid populations can grow quickly and cause serious damage.
Symptoms:
Aphid outbreaks are especially fond of succulent new growth. Aphids attack the tree by sucking the sap from leaves. An affected citrus tree will quickly form curled leaves, leaf yellowing, colonies of aphids, and the attendant dripping honeydew will become visible. This can attract ants, as well as Sooty Mold. Eventually, leaves will die, and twigs will rot and fall off. Aphids can be controlled using insecticides and insecticidal soap on infected areas and treating both tops and undersides of leaves, and all branches and twigs.

2. Citrus Mites
Red Mites are tiny insects that feed on new growth and sometimes even fruit. The Citrus Bud Mite is red or purple and often inhabits the underside of mature leaves, or the delicate folds of emerging foliage.
Symptoms：
Severe infestations can cause leaf drop, low yields, and poor tree health.

Citrus Weeds Management
1. Annual Weeds
The annual weeds are mainly Barnyard grass, Knotgrass, Leptochloa chinensis, Crabgrass, Purslane, Asia minor bluegrass and so on.
