Cold protection for seedlings and rice care

This spring crop, the Northern and North Central provinces are directed to plant 90% of late spring rice, the crop time frame can last until the end of February but it is best to finish direct sowing and planting before February 25.

Localities need to immediately prepare a reserve amount of seeds for sowing or direct sowing in time if severe cold and frost persist. Focus on solutions to protect seedlings from cold and care for spring rice to help the plants grow well, have strong roots, and produce early and concentrated tillers, which are prerequisites for a successful spring rice crop. The things that need to be done immediately are:

- For areas where seedlings have been sown, continue to take measures to keep warm such as covering with plastic (do not use plastic or dark-colored tarpaulin), do not add nitrogen fertilizer and can add phosphate fertilizer, sprinkle decomposed wood ash to keep warm or spray foliar fertilizers containing trace elements such as zinc (Zn), molybdenum (Mo), copper (Cu), Boron (B) ... with the effect of synthesizing nutrients and growth regulators to help seedlings increase resistance to unfavorable weather, but do not treat when the average daily temperature is below 15 degrees Celsius. When the weather warms up, wait for the seedlings to grow new roots before transplanting.

- Choose absolutely safe herbicides for transplanted rice and direct-sown rice.

+ For transplanted rice, use Fenrim 18.5WP (15 gr/Northern sao package), spray or sprinkle 3-7 days after transplanting, keep the surface of the shallow field watered regularly.

+ For direct sowing rice, use Prefit 300EC or NewHeco 600EC (100 ml bottle divided equally into 2 - 3 bottles for 2 - 3 Northern sao, spray to kill weeds 1 - 3 days after direct sowing).

+ Besides the above time, if farmers cannot spray herbicides, 15-20 days after planting, use post-emergence herbicide Pitagor 550WP (25 gr/Northern sao package).

+ Use StarPumper 800WP and Boxer 15GR golden apple snail insecticide when snails appear and cause damage according to the manufacturer's recommendations.

- For newly planted and directly sown rice fields, it is necessary to maintain a shallow water layer on the surface of the field regularly (2 - 3 cm), and not let the field dry out. There is a folk saying "spring rice uses water as a coat", because when the rice is newly planted, the roots have not yet penetrated deep into the ground. If the field is dry on the surface, the rice roots will be easily affected by cold weather, even killing the rice.

Do not apply nitrogen fertilizer on days when the temperature is below 15 degrees Celsius. Regularly check the fields and take care of them when the weather warms up. Take advantage of pruning and early fertilization with synthetic, easily digestible fertilizers, specifically designed to help the rice take root, recover, and tiller easily.

- Spray foliar fertilizer products selectively, prioritizing products rich in trace elements to supplement nutrition and increase resistance to cold and drought for rice plants through leaves such as high-quality foliar fertilizer product Polyfeed 19 - 19 - 19 (5 swallows) combined with concentrated root stimulant, growth stimulant, and tillering stimulant Kithita 1.4SL (DD) to help rice plants quickly grow new, white, healthy roots, and absorb fertilizer early through the roots, helping rice plants to recover, grow healthy, balanced, and tiller early and concentrated.

Polyfeed 5 swallow high-grade foliar fertilizer produced by Israel by Central Plant Protection Joint Stock Company 1, in addition to supplementing 3 macronutrients: nitrogen, phosphorus, potassium for plants, also has 6 trace elements that are indispensable in the growth and development of plants: iron (Fe), manganese (Mn), molybdenum (Mo), Boron (B), zinc (Zn) and copper (Cu) which help rice plants recover quickly after cold weather, synthesize nutrients and form growth regulators to help rice plants stay healthy, withstand adverse conditions such as drought, cold, stimulate root growth, quickly take root, recover green, favorable for rice plants to tiller early and very concentrated.

Using Polyfeed 5 swallows and Kithita 1.4SL (DD) is an effective solution to save rice in cold spring crops, creating the premise for high yield spring crops.
