SAIPORA SUPER 350SC FUNGICIDE FIGHTING AGAINST  SHEATHBLIGHT ON RICE 15/06/2022

Rice is the main and important crop to serve domestic demand and export. However, once intensive farming to increase yield and quality, many pests often emerge. Sheathblight is one of the most dangerous pests, which greatly affects the yield and quality of rice, if we do not prevent it in time.

Sheath blight is caused by the fungus Rhizoctonia solani. The fungus can attack on stems, leaves, spike and rice seeds. However, the disease is most common in the stem and sheath of rice near the water surface. The fungus can also attack the panicle collar and, causing the entire panicles or spikes to be affected. Lesions are patchy, streaky, with a grayish-white color. When the disease is severe, many diseases link together to make the leaves dry, can also make the whole plant dry and the grains are half , completely unfilled.

In rainy, hot and humid weather conditions, the disease thrives. The disease also often causes severe damage in fields using infected rice varieties, sowing thickly, applying fertilizer unbalanced, having excess nitrogen...

In order to manage sheathblight disease, we need to apply many measures such as:

- Use disease-resistant or low-infection varieties for planting and seed treatment. Cleaning the field, clearing the remnants of the previous crop…

- Sow with appropriate density, apply fertilizer in a reasonable balance, avoid excess nitrogen.

- When the weather is suitable for the disease to develop, take proactive precautions such as limiting the use of nitrogen fertilizers, increasing potassium fertilizers...

- Regular monitoring of the field, especially during the period when rice plants are susceptible to the disease from young  to  booting stages. When diseases appear early in the field, stop using nitrogen fertilizers...

However, when the disease has broken out in the field, especially in the field, which is sown with infected seeds and is fertilized with excess nitrogen, we need to use products to timely manage and limit the harm.

To prevent, in addition to plowing and burying weed seeds, collecting weed stalks and stumps left after tilling the land to burn, not letting weeds produce seeds in production fields, etc., the use of chemical products is still a measure. optimal because of its ability to thoroughly kill weeds, reduce labor and take advantage of more time than manual weeding.To prepare for the coming Summer-Autumn rice crop, we would like to introduce to you a very new product of Saigon Plant Protection Joint Stock Company, which is Butoxim 5GR. This is a granular product used for spreading by Saigon Plant Protection Joint Stock Company in research, production and distribution.

 

 Miner has the scientific name Phyllocnistis citrella Staint., family Phyllocnistidae, order Lepidoptera. The  miner occurs in many countries in the tropics and subtropics. The main host of the miner is the citrus family - Rutaceae. In addition, the miner also attacks mangosteen and some other plants.

 

Adult is a small planthopper, with a body 2-3 mm long, the whole body is ash gray, slightly greenish, the wings are opaque with many small brown spots.Eggs are oval, 0.3 mm long, have a pointed end and are attached directly to the leaf surface, leaf axils.Larvae are very small, oval in shape, newly hatched are bright yellow. Age 2 and age 3 are in green. Age 4 and age 5 are golden brown and 2 small wing sprouts.

 

Green bugs specialize in the fruit of citrus groups (oranges, tangerines, lemons, grapefruits, kumquats...), some people call them orange bugs, or orange suckers. Their scientific name is Rhynchocoris poseidon or Rhynchocoris humeralis.

 In Vietnam, yellow leaf curl disease is very common on papaya trees, especially the disease is often severe in areas of high and continuous planting, areas with hot and arid climates. The disease has significantly reduced the yield and quality of papaya. Gardens that are infected early when the plants are young may not yield. However, up to now, many gardeners still do not know the cause and how to fix it.

 

 Spider mites are common pests on citrus trees, especially in hot and dry climates that are suitable for spiders to grow and cause severe damage.The group of harmful spiders is usually very small in size, unlike the natural enemy spiders.Spiders have a very short life cycle, high reproductive ability, create many generations in a year, so it is easy to break out into epidemics in a short time.

 

 This group includes species that are generally very small in size, causing damage by sucking plant sap (on leaves, fruits, branches, stems).

There are many species of mealybugs present on the group of Oranges,Tangerines,Grapefruits and Lemons (Citrus), which can be divided into 2 groups:

+ Group of sticky mealybugs with common varieties such as Lepidosaphes, Aonidiella, Coccus and Saissetia.

+ Group of flower mealybugs with common genera and species such as Pseudococcus, Planococcus and Icerya purchasi.

Dry branches and berries disease often appear to be common damage on coffee gardens during the rainy season. The disease causes death of branchs, dry fruit, severely affects the canopy structure and coffee yield if not paid attention to prevention.

  

 Pink disease commonly causes diseases on rubber plantations in the rainy season, especially on garden from 4-8 years old. This year, rubber has to go through a period of severe drought, weakening the tree, so now in tnshe rainy season it is easy to get infected. Therefore, it is necessary to pay attention to good management to avoid affecting the garden.

In recent years, the area of citrus has been expanded because it is a fruit tree with high economic efficiency. However, in order to sell at a high price, not only in quality but consumers also require the external beauty of the fruit, so pest management on citrus is a matter of great concern to farmers. The hot season is a favorable condition for thrips to develop and cause damage, affecting the commercial value of fruit.
