| Crops | Disease | Dosage |
| Rice | Rice Blast | The amount of hectares 450-600 grams, when tillering field sporadic acute lesions and diseased center, the timely pesticide control leaf blast; prevention panicle blast to prevention, to various facilities in the late booting stage and heading stage drug once. Use as a foliar spray. |
| Potato | Late Blight | The amount of hectares 400-550 grams, which is about to be foliage spray or onset sporadic lesion in the field continuously sprayed 2-3 times at an interval of 7-10 days of medication. |
| Cotton | Cyanosis | Soaking seed than 1:400 drug formulation 600 g / hectares, spray the stem base and leaves in the early stages. Spraying liquid 50 ml per plant. 7 days after spraying once. |
100Billion live spores / g Bacillus subtilis WP is bacterial genus Bacillus, for rice blast has a good preventive effect.
Mechanism of action:
Bacillus subtilis bacteria belonging to the genus Bacillus, for rice blast has a good preventive effect. The agents can inhibit the growth of pathogenic bacteria secrete antimicrobial substances, and to hyphae fracture, disintegration and dissolution of the cell wall of the pathogen to perforation, deformities, etc., so that pathogens lose scalability.
(1) Rinse or wash field with water or alkaline water in time.
(2) Timely trim the drug damage part of the crops in time, and remove the part of the drug damage.
(3) Spray Fertilizer to improve crop resistance and recover crop growth.
Tomato yellow leaf curl virus (TYLCV) causes one of the most devastating emerging diseases of tomato worldwide (Czosnek, 2007). The virus (genus Begomovirus, family Geminiviridae) is transmitted by the whitefly Bemisia tabaci. From the early 1960s, TYLCV has quickly spread from the Eastern Mediterranean Basin to the entire Middle East, CentralAsia, North and West Africa, southeastern Europe, the Caribbean islands, southeastern USA, Mexico,the Southern Indian Ocean islands and Japan (Lefeuvre et al.,2010).In severely affected regions, crops may be totally lost (Picó et al., 1996).The tremendous economic impact of TYLCV and the swift spread of TYLCV disease worldwide have triggered a large body of research tackling many aspects of the viral disease over the last 30 years: molecular biology, plant–virus–vector relationship, epidemiology, disease management and breeding for resistance.
The rapid spread of the viral disease is caused by whitefly pressure and by high transmission efficacy. A single whitefly is able to inoculate a plant following a 15-min acquisition period and a 15-min inoculation period. In the field, inoculation can occur immediately after transplantation. Infected seedlings will remain stunted and will not yield fruits. Apart from whiteflies,TYLCV can be transmitted by grafting, by agroinoculation and by DNA-coated particle bombardment. It is not seed transmitted. The relationships between begomoviruses and whiteflies are complex. TYLCV is transmitted by B. tabaci in a circulative manner.
TYLCV and some related viruses influence several features of insect pathogens: they affect B. tabaci longevity and fertility and are sometimes transovarially transmitted; they affect the whitefly transcriptome, activating the expression of genes related to the whitefly immune response (Luan et al., 2011)

TOMATO SPOTTED WILT VIRUS (TSWV)
The first description of the ‘spotted wilt’ disease of tomato occurred in 1915 in Australia (Brittlebank, 1915). The disease was later shown to be transmitted by thrips (Pittman, 1927) and caused by a virus, which was named Tomato spotted wilt virus (TSWV) (Samuel et al., 1930). Although the virus was soon reported in many other countries, the more recent worldwide dispersal of Western flower thrips (Frankliniella occidentalis), the major vector of TSWV, led to the re-emergence of TSWV as a major agricultural pest in the 1980s with worldwide losses estimated to be in excess of US$1 billion annually by 1994 (Goldbach and Peters, 1994).
The continuing economic importance of TSWV is a result of: (i) its worldwide distribution and wide host range (>800 plant species), including tomato, pepper, lettuce, peanut and chrysanthemum; (ii) the significant crop losses resulting from infection; and (iii) the difficulty in managing the thrip vectors, and hence the virus (reviewed in Adkins, 2000; Pappu et al., 2009). TSWV causes variable symptoms, including necrotic/chlorotic rings and flecking on leaves, stems and fruits, with early infections leading to one-sided growth, drooping leaves reminiscent of vascular wilt, stunting or death . Later infections produce unmarketable fruit with striking chlorotic/necrotic ringspots that often appear only when the fruit reaches full colour (reviewed in Chiemsombat and Adkins, 2006). Novel integrated management strategies have been developed for TSWV because the complex vector–virus relationship and the rapidity of transmission limit the effectiveness of insecticides (reviewed in Funderburk, 2009).

control plant virus with Lin chemical Lentinan
In the prevention and control of virus diseases,
1.choose the right product for control virus disease.
2.we should pay attention to killing insects, such as aphids and other small insects that transmit virus diseases.
3.combining fertilizers to improve plant immunity.
Lentinan from Lin Chemical a product for controlling virus disease containing nutrients. Which helps you control virus in plant effectively.
A majority of plant viruses are dependent on vectors for their transmission and survival. Insects, mites, nematodes and protists all mediate the transmission of plant viruses. Insects are the most common of the vectors and, among these, aphids account for the transmission of 50% of the insect-vectored viruses (Brunt et al., 1996; Nault, 1997).
Aphids are exquisitely designed for their roles as vector. Piercing–sucking mouthparts facilitate the delivery of virions into plant cells without causing irrevocable damage. With the option of asexual reproduction, aphid populations can increase at extraordinarily high rates, thereby potentiating disease epidemics and furthering the short- and long-distance spread of viruses.
Additionally, aphids are globally distributed and there are more than 200 vector species identified, a number that is most likely a gross underestimate (Brunt et al., 1996; Eastop, 1983; Hull, 2002; Nault, 1997).
