Yellow apple snail appears in high density and damages summer-autumn rice. Mr. Le Xuan Tu, Director of the Sub-Department of Cultivation and Plant Protection said that the yellow apple snail harms the newly sown rice stage, greatly affecting the growth and development of rice plants, if high density can make 100% loss of trees in the field. In order to minimize the damage caused by yellow apple snail, farmers need to apply a combination of manual measures and chemical measures to increase the effectiveness of killing snails. When the density of snails is high, snails are small, in order to thoroughly limit harmful yellow apple snails, people use drugs with active ingredients, such as Metaldehyde, Niclosamide to eradicate. Dosage according to the manufacturer’s instructions on the packaging. People should note that when using the drug, it is necessary to maintain the water level from 3-5cm to prevent high efficiency; Spray in the early morning or late afternoon because this is the time when snails are most active. Pesticides to prevent snails are often toxic to aquatic animals, so they should only be used when the snail density is high, avoiding use in rice and fish fields. In addition, other objects are causing harm with an increasing trend, such as: rats harming 71.2 hectares, leaf rollers 60 hectares, acacia caterpillars 50.2 hectares, thrips 36 hectares…. The Sub-department recommends that farmers keep a close eye on the fields, closely monitor the situation of harmful effects, proactively implement timely and effective prevention measures.

The apology was made by Prime Minister Prayuth after the Thai public expressed displeasure over the slow implementation of the vaccination campaign. Prime Minister Prayuth said that despite ordering a large number of vaccines, the Thai government has only received a small amount of the vaccine. Vaccines are now concentrated in large vaccination points, with faster vaccination rates, where almost all of the vaccines they are distributed are used up. Although Thailand has been transferred technology, the production of a vaccine takes a long time, not to mention the quality control procedures, which every country has to face, Prime Minister Prayuth said.

In addition, vaccination is currently focused on the most vulnerable populations in high-risk outbreak areas in the Thai capital, in order to prevent the disease from spreading, as well as to maintain the operation of health facilities. factory. This affects those who have already signed up for vaccinations, Prime Minister Prayuth acknowledged. In addition, Prayuth also said that the vaccination campaign involved many organizations, and the lack of harmony in the coordination process also affected the speed of vaccination deployment. The Thai government has ordered 100 million doses of the Covid-19 vaccine, with plans to vaccinate 50 million people, or 70% of the population, this year. Prime Minister Prayuth said Thailand’s goal is to buy enough vaccines to raise vaccination rates to 80-90%.

When the car has generated the smell of rotten eggs (H2S), the main cause usually comes from a malfunctioning car exhaust converter. Because then, sulfur gas will be spilled into gasoline and create extremely toxic H2S (at concentrations above 25 ppm can be fatal). But due to a problem with the flue gas converter at that time, re-filtering the H2S was completely impossible, leading to the vehicle’s exhaust emitting the smell of rotten eggs.

The smell of burning oil

The smell of burning oil is often caused by a direct leak from the combustion chamber, which makes the combustion not optimal. From there, it will make users feel an unpleasant smell like burning oil or more smoke.

Smell of diesel engine

This is a typical case of diesel engine vehicles. Since the burning of a diesel engine as well as the engine power of a diesel-fueled vehicle is usually higher than that of a gasoline, you will feel a stronger diesel smell when you drive on gasoline.

The smell of gasoline in the exhaust gas

If there is a smell of raw gasoline in the smoke, it means there is a problem in the car’s carburetor. At that time, more gasoline will enter the carburetor than usual, leading to the fact that gasoline and oxygen do not follow a predetermined ratio and causing the combustion in the chamber to not go as planned. From there, in the exhaust of the car, there will be a stagnant smell of gasoline because the combustion is not completely efficient.
