IPM Post Card #1 - If you don’t
look, you won’t know.
April 11, 2003
Black cutworm: Callaway Co. Trapping – No moths caught
this week.
Watch for updates.
Alfalfa
Weevil: Reports of hatching – watch for early damage. Small
green legless worms; black head - white strip down backs - feeding in alfalfa
tops.
Collect
10 alfalfa stems per survey site. Tap the stems inside a light colored bucket
and count weevils - inspect the tops for weevils. One or more AW per stem or 25%
feeding = economic threshold. Within 7 - 10 days of 1/10th bloom = harvest. If
treatment needed use: Baythroid, Dimethoate, Furadan, Imidan, Lorsban, Mustang,
Warrior T, or Warrior T + Zennon. Check label for rates and harvest intervals.
The scouting program was unable to get enough acres to continue. Thanks to everyone for their support in the past. Other IPM programs will be held this spring and summer. I will keep you informed. Jim Jarman, Agronomy Specialist

IPM Post Card #13 - If you don’t look, you won’t know. July 3, 2003
European corn borers: 0 moths caught in ECB trap this week. We should be between generations.
Grasshoppers: Small pockets of young hoppers seen across MO. Control now while young before they spread into crops. Economic infestation seen in Audrain County. Control while they are small and still where they hatched. Now they are easier to kill and are found in small areas that may be easier to spray. In a month they will have wings and can spread across fields.
Potato leafhopper: Continue to watch this pest. Reduces feed value and stunts alfalfa. Reports of PLH damaging newly planted and newly harvested fields. Four PLH in 3” tall alfalfa/20 sweeps is economic threshold. In gardens it will attack snap beans and, of course, potatoes.
Chinch bug: Will leave harvested wheat fields and migrate into adjacent milo and corn. Watch field margins.

Jim Jarman, Agronomy Specialist
IPM Post Card #14 - If you don’t look, you won’t know. July 18, 2003
European corn borers: First generation was light. Some seen in transgenic corn’s refuge fields of non-transgenic corn. Second generation attracted to tasseling/pollinating corn. Eggs laid at leaves, above and below the ear.
Grasshoppers: Continue to watch for small/wingless hoppers. They are easier to kill and are usually found in small areas outside of fields that may be easier to spray.
Potato leafhopper: High numbers continue to be seen. Injury reduces feed value and stunts alfalfa. Yellow alfalfa leaf tips called hopper burn. Four PLH in 3” tall alfalfa/20 sweeps is economic threshold.
Blister beetles: They are out and about. Watch alfalfa particularly if harvesting 2nd and 3rd cuttings for horses. Survey and spray if needed to keep blister beetles out of horse hay.
Soybean Cyst Nematode (SCN): Watch for damage and survey with soil samples to evaluate threat to soybean yields and need for SCN management in fields.

IPM Post Card #15 - If you don’t look, you won’t know. July 25, 2003
European corn borers: No ECB moths captured in Callaway or Boone Co. since First of July. First generation was light. Some seen in transgenic corn’s refuge fields of non-transgenic corn. Second generation attracted to tasseling/pollinating corn. Eggs laid at leaves, above and below the ear.
Grasshoppers: Continue to watch for small to medium sized wingless hoppers. They are easier to kill and are usually found in smaller areas outside of fields that may be easier to spray.
Potato leafhopper: Numbers down at this time. Injury reduces feed value and stunts alfalfa. Yellow alfalfa leaf tips called hopper burn. Damage will remain even if PLH are no longer in field. Must cut alfalfa to start regrowth.
Blister beetles: They are out and about. Watch alfalfa particularly if harvesting 3rd cuttings for horses hay. Survey and spray if needed to keep blister beetles out of horse hay. Turn conditioned windrows before leaves dry to shake dead blister beetles on to ground.
Soybean Aphid a.k.a. Chinese Soybean Aphid: First MO economic infestation since introduced in 2000. Ralls Co. field near New London infested. Usually, SA more likely to occur in fields with low potassium. Trace numbers seen in Callaway Co. earlier this season. It is the only aphid you will find infesting soybeans.

IPM Post Card #17 - If you don’t look, you won’t know. August 8, 2003
European corn borers: Second generation attracted to tasseling/pollinating corn. Eggs found around leaves, above below and at the ear. Look for worms in leaf axils. Economics of treatment tied to yield – if yield is reduced by drought,
Grasshoppers: Big yellow grasshoppers have wings. They may begin moving into corn and milo. Continue to watch for small - medium sized wingless hoppers. They are easier to kill and are usually found outside of fields in smaller areas that may be easier to spray. I saw a very late hatch last week. They may mature too late to seriously hurt forages and crops.
Potato leafhopper: Numbers continue to be high for this time of year. Continue to watch.
Blister beetles: Watch alfalfa particularly cuttings for horse hay. Survey and spray if needed to keep out blister beetles. BB and their “blood” can contaminate forage when conditioner rollers crush them.
Soybean Aphid: Two more MO fields found infested. SA more likely in low potassium (K) fields. Can cause yellowing, crinkled leaves and stunted plants. Take care in control. Some insecticides may increase problem. Warrior, Mustang and Lorsban are recommended.
Call me if you see or suspect pests or need survey & pesticide recommendations.

IPM Post Card #18 - If you don’t look, you won’t
know.
August 15, 2003
European corn borers: Look for worms in leaf axils. Economics of treatment tied to yield – if yield is reduced by drought, it takes a higher infestation for treatment.
Grasshoppers: Big yellow grasshoppers have wings. Smaller ones are still around. They may mature too late to seriously hurt forages and crops.
Potato leafhopper: Numbers high in alfalfa. Continue to watch.
Blister beetles: Watch alfalfa particularly cuttings for horse hay. Survey and spray if needed to keep out blister beetles. BB and their “blood” can contaminate forage when conditioner rollers crush them. Just turning windrows to shake out BB not enough to insure horse safe hay.
Soybean Aphid: SA more likely in low potassium (K) fields. High aphid numbers in soybean are SA. Take care in control. Some insecticides may increase problem – poor aphid killers and good beneficial killers. Warrior, Mustang and Lorsban are recommended.
Soybean Diseases: Charcoal Rot = drought + thin soils. Seen as yellowing areas.
Corn Diseases: Aflatoxin = drought + damaged grain, trashy grain or poorly stored grain.

August 22, 2003
Soybean Aphid: SA has blown across MO. Many fields seeing high numbers. More likely in low potassium (K) fields. Warrior, Mustang and Lorsban are recommended. Do not use Pounce. Economic threshold is 250 SA / plant or 25 / upper trifoliate. Variety sensitive – check all fields.
Spider Mites: Being found! Watch treatment that may stimulate soybean aphid. Survey yellow spots – can spread across field and cause 100% defoliation.
Grasshoppers: Big yellow grasshoppers have wings. Continue to watch.
Potato leafhopper: Numbers high in alfalfa. Can kill alfalfa right after cutting.
Blister beetles: Watch alfalfa particularly cuttings for horse hay. Survey and spray if needed.
Soybean Diseases: Charcoal Rot seen on thin soil as yellowing areas.

August 29, 2003
Soybean Aphid: SA has blown across MO. Most fields have some – watch numbers. Economic threshold is 250 SA / plant or 25 / upper trifoliate. Variety sensitive – check all fields. Numbers decline as plants dry or mature.
Spider Mites: Being found! Watch treatment that may stimulate soybean aphid. Survey yellow spots – can spread across field and cause 100% defoliation.
Grasshoppers: Big yellow grasshoppers and red-legged have wings. Continue to watch.
Potato leafhopper: Numbers may be high in alfalfa. Can kill alfalfa right after cutting. Number declining in some fields especially in northern MO.
Milo: Watch for sorghum webworm in heads. Also, corn earworm moths out – may infest heads since this may be the most attractive crop around now.
Soybean Diseases: Charcoal Rot seen on thin soil as yellowing areas.

IPM Post Card #21 - If you don’t look, you
won’t know. September 5, 2003
Soybean Aphid: Finding in most fields - watch numbers. Variety sensitive – numbers drop on maturing plants.
Spider Mites: Watch treatment that may stimulate soybean aphid. Rains did more than a spray.
Milo: Watch for sorghum webworm in heads. Also, corn earworm moths out – may infest heads since this may be the most attractive crop around now. Also grasshoppers.
Soybean Diseases: Charcoal Rot seen on thin soil as yellowing areas.
Corn Diseases: Aflatoxin = drought + damaged grain, trashy grain or poorly stored grain.
If grazing corn – shelling removes grain and aflatoxin but nitrates remain = test and watch cattle.
Harvest quickly: Drought damaged corn stalks are weak, prone to rots and lodge easily & quickly. Moldy stalks increase dust problems – protect your lungs!

Post Card #22 - If you don’t look, you won’t know.
September 12, 2003
Soybean Aphid & Spider Mites: Numbers dropping due to rains and maturing soybeans.
Milo: Watch for sorghum webworm in heads. Other worms may infest heads since grain sorghum is the most attractive crop around now. Also watch grasshoppers.
Soybean Diseases: Charcoal Rot seen on thin soil as yellowing areas.
Corn Diseases: Aflatoxin = drought + damaged grain, trashy grain or poorly stored grain.
If grazing corn – shelling removes grain and aflatoxin but nitrates remain = test and watch cattle.
Harvest quickly: Drought damaged corn stalks are weak, more rain will stimulate rots and stalks will lodge. Black Corn: It has been given a name. Moldy stalks increase dust problems – protect your lungs! We have recommendations for dust protection.
BE CAREFUL: Practice safety during harvest. A young girl almost drowned in corn last week in the NW corner of our region. Don’t let the harvest crunch, crunch you!

Milo: Watch for sorghum webworm and other worms in heads. Also watch grasshoppers.
Corn: If grazing corn stalks – test and watch cattle – nitrates may still be a problem.
Harvest quickly: Drought damaged corn stalks are weak, more rain will stimulate rots and stalks will lodge.
Black Corn: Moldy stalks increase dust problems – protect your lungs!
Estimating corn yield: (# ears per 1/1000 acre) X (Number of rows) X (Number of kernels per Row) / 90. 30-inch rows, 1/1000 of an acre is 17.4 feet. If 20 ears had 16 rows and 36 kernels per row, the estimated yield would be 166 bu./acre. (26 X 16 X 36 /90 = 166)
Wheat: Saved seed – clean and use seed treatment. We have recommendations.

Jim Jarman, Agronomy Specialist – University of Missouri Extension Programs are open to all. Theses post cards are available at: http://extension.missouri.edu/callaway/jarman-news/postcard%20from%20Jim..htm
ATTENTION: One of the post cards is a survey. Please fill
it out and just drop it in the mail.
Thank you for your participation in the 2003 IPM post card
season. A survey and the last IPM update card are included in this letter.
Please fill out the survey post card and just drop it into the mail. I welcome
any and all comments on the “post card” style of passing on pest management
information. I hope to make the mailings better for next year.
Economic restrictions on mailings have caught up with our
programs. The IPM post card system was started to give current, short and easy
to read information that was immediately useful. It is now, equally as
important, an economic as well as efficient method of communication.
As always, I am available and welcome any comments or
direct requests for information. Let me know if there are any topics needing
special attention. I welcome the opportunity to hold meetings or programs on
important issues
Sincerely yours
