  • What pesticide gives good control results against corn borers?

    Which pesticides can control corn borers? Please introduce in detail. For corn borers, the following methods can be used for control: At the funnel stage of corn, broadcast Miral (isofenphos-methyl) into the funnel, at a rate of 1 kg/mu. During the ear stage of corn, the chemical irrigation control methods include: pouring chemical solution into the tassel: 25% bisultap aqueous solution at 500 times dilution...

  • When is the best time to control corn borers?

    When is the best time to control corn borers for the best results? Please give guidance. Corn is vulnerable to pests from emergence to maturity, and to achieve high quality and high yield of corn, proper pest control is very important. Especially for the damage caused by corn borers, one must not be careless. Corn borer, also called stalk borer, is a relatively...

  • How should corn borers be controlled? A detailed explanation of control methods

    How should corn borers be controlled properly? Please explain the methods. Corn borers can be controlled by referring to the following methods: Controlling corn borers at the corn whorl stage: for fields with a damaged-leaf rate of 10%, carry out full treatment at the end of the whorl stage; where the damaged-leaf rate is below 10%, selective treatment may be done as appropriate; where the damaged-leaf rate exceeds 20% or there are more than 30 egg masses per 100 plants, treat once at the mid-whorl stage and once at the end of the whorl stage respectively...

  • What are the causes of corn borer outbreaks?

    What are the causes of corn borer outbreaks? Please explain. The causes of corn borer outbreaks are as follows: (1) Insect population base: the size of the insect population base from the previous generation is an important factor affecting the severity of corn borer damage. A large insect population base, under suitable environmental conditions, often causes severe damage. ...

  • How to Control Weeds in Corn? A Detailed Guide to Practical Weed Control Methods

    How to prevent weed damage in corn? Please provide prevention methods. Weed damage is one of the factors restricting high and stable corn yields. The annual area affected by weeds in corn fields in China exceeds 350 million mu-times, causing about 9.5 billion kg in corn losses each year. In response to the weed species present and their damage characteristics, an integrated control strategy should be adopted that takes agricultural control as the foundation, ...

  • What are the control methods for the small brown planthopper on corn?

    How to control the small brown planthopper on corn? Please explain the methods. When the small brown planthopper breaks out in corn fields, frequent and heavy applications of pesticides are usually required to bring the population under control. In recent years, accidents of phytotoxicity to corn caused by improper pesticide use have occurred frequently in production. Therefore, safe pesticide use should be paid attention to when controlling the small brown planthopper....

  • What are the control methods for corn borers?

    How to control corn borers? Please explain the methods. Corn borers (corn borer) are a major pest of corn. In years with severe infestation, they can reduce corn yields by more than 20%. Their larvae bore into the main stalk and ears, which can break the main stalk of corn, causing reduced yield and quality. In the past, controlling corn borers mostly used methods such as pouring pesticide solution into the whorl, spraying, or applying poisoned soil into the whorl, which was labor-intensive and ineffective, and easily caused crop damage and human and livestock poisoning. Using granule formulations to control corn borers not only has low cost, saves labor, and is effective, but also is unlikely to cause human and livestock poisoning or crop damage. The following points should be mastered:

  • How to control weeds during summer corn cultivation?

    How to control weeds when planting summer corn? Please explain the methods. When planting summer corn, you can refer to the following two methods for weed control: The "seal-and-kill" weed control technique involves a "seal-and-kill" treatment before corn emergence after sowing, that is, using a soil-sealing herbicide in combination with a non-selective herbicide, so that a single application achieves both soil sealing and killing of visible weeds...

  • How can aphids in cornfields be controlled effectively?

    How to control aphids in cornfields? Please explain the methods. Corn aphids, commonly known as "greasy bugs" or "honey bugs", harm not only corn but also crops such as sorghum and barley. They pierce and suck plant sap. Aphid numbers are very low at the seedling stage, but surge during the ear stage, secreting large amounts of "honeydew", which forms a black mold-like layer on the leaves, affecting photo...

  • How to Prevent Corn Herbicide Damage to Watermelons

    Some readers have asked: some corn field herbicide products are labeled as not to be used on certain corn varieties. Is this because different corn varieties have different sensitivities to these herbicides, and what issues should be noted when using these herbicides in production? Different varieties of corn do indeed differ in their sensitivity to certain herbicides...
