Pesticides are one of the commonly used products during rice cultivation. However, before and after rice heading, both early rice and late rice should be carefully used with some pesticide products to avoid unnecessary economic losses. Let's take a look at the following small series to learn about the use of pesticide products before and after rice heading: 1, triazolone Before rice heading, there are often rice blast and white leaf blight hazards, which are commonly used to control triadimefon (pust rust), but improper use can lead to short and severe heading of rice leaves. The mechanism of triazolone fungicides to control diseases is to inhibit the activity of monooxygenase in fungi, destroy the biosynthesis of ergosterol, and cause cell membrane damage and death. It can also inhibit the gibberellin biosynthesis in plants, so that the gibberellin which promotes cell elongation cannot be synthesized, so that the plants are dwarfed, and the leaves and fruits are short. 2, diniconazole In the early stage of late rice heading, pesticides such as diniconazole, such as 12% carbazole wettable powder, are used to control rice false smut. The amount of the drug is excessive, and it is prone to difficulty in heading the late rice, or the half of the stalk will stop. After using the diniconazole-containing pesticides such as Qujingxing and Heguoli in the rice break stage or the early stage of the heading, the rice in different areas showed different degrees of drug reaction, and the growth of the internodes of rice was affected. "Phenomenon, can not normally head. After the occurrence of phytotoxicity, early spraying of gibberellin has a certain detoxification effect, generally 2 grams of 920 per mu, and 50 kg of water. 3, arsenic preparation Improper use of arsenic preparations on rice can cause phytotoxicity to rice, which is not strong or the rate of seed setting is reduced. At present, tricyclic azole, indole, and prochloraz are generally used in the production to control rice blast, and it is preferable to use these agents alternately when using the drug repeatedly. 4, azole fungicide Precisely use imidazole fungicides before and after rice heading, use well, prevent disease increase; bad use, will affect heading grouting. The compounding agent of oxazolol and Jinggangmycin, such as Wensu, etc., propiconazole, diniconazole, thiofuramide single agent, such as enemy force, Heguoli, Manchu, etc., the effective period of these drugs can generally reach More than 15 days, it is effective for controlling rice sheath blight. It should be noted that azoles, oxazolol, oxazolol, propiconazole and other azole fungicides can inhibit the formation of gibberellin in rice, and use it in the upper part of rice for long-term use, especially when used in large quantities. It may inhibit the lengthening of the internodes, resulting in difficulty in heading and affecting rice filling and fruiting. 5, glyphosate It is a great hazard to spray glyphosate at the booting stage of rice. Misapplication of glyphosate into hybrid rice fields can cause large-scale damage to rice, and the rice fields cannot be harvested normally, and the yield loss is 80% to 100%. Glyphosate is a systemic endocytic herbicide . The differentiation site of young spikes is prone to phytotoxicity, causing symptoms such as dead heart and abnormal ear. In the rice field, after spraying the glyphosate, the appropriate amount of gibberellin and potassium dihydrogen phosphate can be sprayed in time to promote the growth and development of the young spikes. After 7 days, the appropriate amount of urea can be sprayed. Generally, the remedial effect is better in the stage of rice tillering and early stage of panicle differentiation; by the booting stage, especially in the late booting stage, the browning and necrosis of the base of the cob is poor, and the remedial effect is poor. More pesticide knowledge , please pay attention to China Pesticide Network Paintball is an equipment intensive sport and in order to safely conduct a game, every player requires a marker with propellant to fire the paint, a mask to protect the eyes and face, paintballs, and a loader to hold them. To ensure safety off the playing field, a barrel sock or plug for the marker is also compulsory. Paintball markers are powered by the expansion of gas stored in a compressed gas bottle.
